Hello all,

I really like what the last DT firmware update brought to us but I've found it rather difficult to actually access all these new functions. When I look around on this forum then it seems like I'm not alone with this problem. MIDIOX is a great MIDI debug and testing tool but I don't think it is really suited as a device editor. I've found it especially cumbersome and cryptic to use with my DT25. So I created a small editor for my amp.

<a target=new href=" class="jive-image" src=""/>

The">">The project page can be found here.

The editor is still in alpha stage and some functions are still missing but it runs quite stable here on both Windows and Linux.  It would be great if someone could test the latest release and give some feedback.

Kudos Rollo69. What a great piece of work. If only I had a PC ??? Hopefully someone will find a way to compile it for OSX?

It is a complete enigma to me why Line 6 released this update for the DT amps without an editor?

Re: DT Editor
by talwilkins on 2012-11-20 12:27:04.0420

Looks fantasic! I will try it and let you know my findings!

Thanks, you rock!

Re: DT Editor
by rollo69 on 2012-11-20 13:02:42.4790

That would be great.

Re: DT Editor
by rollo69 on 2012-11-20 13:06:23.6810

Exactly my thoughts.

I'm not going to buy a Mac but it may be possible to install OSX into a virtual machine and then compile a Mac version there. I'll try this when the Windows version has reached a stable state.

Norton keeps deleting setup, saying it's a security risk. Any idea what's up???

Re: DT Editor
by lowellhall on 2012-11-20 13:24:40.8400

This looks awesome, thank you can't wait to try it. Line 6 should be paying you for doing their job lol

Re: DT Editor
by Rowbi on 2012-11-20 13:32:37.8500

looks very good.

I'm going to watch this thread, so when you release new versions please let us know by posting here so we can get hold of it.

I will try this out when I have a spare couple of hours and let you know any issues.


Re: DT Editor
by rollo69 on 2012-11-20 13:37:13.8120

Hmm, I have no idea what's going on. I think we have a Norton machine somewhere at the office. Maybe I can get a chance to test the setup there.

In the meantime I've uploaded a plain zip file with the exe. Just unpack this one and run the contained executable.

Re: DT Editor
by evilmikehoo on 2012-11-20 14:02:44.9540

Okay, that did the trick. Now just to mess around with it. By the way, a desktop shortcut doesn't seem to work, but it loads from documents.

Re: DT Editor
by evilmikehoo on 2012-11-20 14:55:31.0870

Just got done messin' around. I don't know much at all, but I know what works for me and this works a lot better than MidiOx. Well, MidiOx works, but this is so much quicker & easier!!! Can't wait 'til ya get it all workin'! Thanks Man! Really appreciate what you've done!

Re: DT Editor
by BigChas52 on 2012-11-20 15:08:32.1360

Absolutely brilliant Rolf!!  Works great with DT25 in Windows 8 64 bit with Midi-Sport UNO 

I love that it polls the amp and shows current settings.  That's the biggest downfall of the iPAD/TouchOSC app.

Nice work!!

Re: DT Editor

Very good indeed.

I'm testing here and this wonderful.

Now I can finally retire my HD 500.

Re: DT Editor
by kisuco007 on 2012-11-20 16:15:46.2480

Congratulations inventor friend.

The Line6 have to pay you for this work.

Where about 70% of PC users use and did not.

I was very pleased with his work.

Re: DT Editor
by geppert on 2012-11-20 17:16:44.4570

Hey Rolf,

If Line 6 had the smarts they should offer to buy or licence this from you.

Re: DT Editor
by jc_anderton on 2012-11-20 23:51:17.4100

Amazing work - So much easier than using Midiox!  You do realise you are going to get  feature requests now

A Save/Load patch function would be great!

Re: DT Editor
by rollo69 on 2012-11-21 01:07:10.1700

I've feared that this would happen.

Loading works already but saving is a bit tricky. I have to put some more brain power into that.

Re: DT Editor
by jc_anderton on 2012-11-21 02:51:28.5430

Obviously we'll need :

Web upload/download of custom tones

some nice amp style skins

VST plug-in with audio routing

built in coffee maker

Any time this week, no rush

Re: DT Editor
by evilmikehoo on 2012-11-21 06:55:16.1610

Quick question - How are the pots set up? Are they 0 to 10 and same mark positions as on the DT50? Or are they percentages or clock positions? Since the knobs spin completely around, markings might be a bit helpful. Oh, and by the way, the shortcut IS working. I'm having a blast!

Re: DT Editor
by kisuco007 on 2012-11-21 11:14:23.7640

Hello, I was now moving in the amp, and it stopped working. I looked at the fuse input saw it was burned.

Is it just buy another and put fuvivel and it works properly again.

Where can I encontar, and which model the subistituir burned.

Thank you.

Re: DT Editor
by frankrodler on 2012-11-22 03:49:26.6570

Really a great progamm.

Line6 should give you a DT25 AND a DT50 for free that you bring this tool to a final version (V1.0)

Also it should be linked from the download area.

I'm quite shure that this tool brings Line6 a lot of new (additional) customers.

Which tube guitar amp can be fully controlled by a computer, not so many I think.

I'm looking forward to the next releases.

Re: DT Editor
by rollo69 on 2012-11-24 06:39:59.2300

Do you have any idea what you did when you burned the fuse? I literally flooded my DT with a wild mixture of MIDI messages over hours but I've never seen something like that.

Re: DT Editor
by rollo69 on 2012-11-24 07:08:11.8380

Thank you all for your kind words.

I've just uploaded a new version. This version includes a much better knob behaviour and overall enhanced stabillity. Loading and saving works partly here but it is disabled until  I get some informations from Line6.

Re: DT Editor
by evilmikehoo on 2012-11-24 07:58:47.4740

Re: DT Editor

Re: DT Editor

Glad you got it working.

Does Norton have a log file, report or something like that? I'd really like to understand what is going on here.

Re: DT Editor

Re: DT Editor
by geebake on 2012-11-27 13:24:40.9060


I'm a .Net developer myself. I went on a vacation over Thanksgiving thinking that I would write an editor when I got back. You beat me to it and probably did a nicer job than I would have! Very, very nice. I have about a hundred feature requests! Again, really, really nice.


Re: DT Editor
by therightclique on 2012-11-27 18:08:08.3290

Awesome. It was so frustrating that Line 6 released an update that basically nobody could use. Why their engineers couldn't have released the update WITH an editor is beyond me. MidiOX did nothing but send a stream of nonsense to my amp, causing a ticking sound and flickering lights. Totally unusable for human beings.

I have a Mobilizer II on the way, but am used to using a PC. Can't wait to try this when I get home from work.

I've only had my DT50 for a few weeks. Sounds so great with my HD500. If only I hadn't broken the pathetically weak preset knob on the HD500, making it unusable without a computer.

Re: DT Editor
by Stueyd on 2012-11-28 06:12:30.1040


Now all we need is an electronics whizz to build a floorboard so we can switch between saved settings on stage.

Yeah, that's what I thought i'd bought my HD500 for too :-)

Re: DT Editor
by MartinDorr on 2012-11-29 09:19:34.6790

Looks really good. Too bad I can't use it yet (MAC user).

I have a few questions:

  1. The project page screen shot shows Volume dial in the Master section. Does this really work? I did not see any MIDI control documented for it.
  2. Are the I,II,III,IV selection in the Preamp A and B sections select the program slot, i.e., the channel/voicing combo's 0-7 as Line 6 labeled them?
  3. Are the I,II,III,IV selection in the Poweramp A and B sections select the voicings used when this channel is selected? If yes, maybe Voicings (as Line 6 calls them) would be a better label?

Great contribution like many said before. I looking forward to using it in the future.


Re: DT Editor
by rollo69 on 2012-11-29 10:34:15.7040

Hi Martin,

the master does indeed work, but only in one direction. If you move the master knob on the amp then the knob on the screen will follow. But it looks like it's not possible to control the master knob on the amp over MIDI. I guess this is disabled for security reasons as you could accidently fry your ears just by sending the wrong MIDI message. The CC number for the knob is 20 btw.

The numbered switches in the preamp and poweramp sections control two different things.

The ones in the preamp area switch between the "presets" of the channel just like the real I-II-III-IV switch on the amp.

The four switches in the poweramp area represent four different feedback modes of the poweramp. The manual calls this setting "Topology / Negative Feedback Loop" and the four possible values are called "I - Tight", "II - Loose", "III - Zero Negative Feedback" and "IV - Resonant". I don't know what actually happens inside the poweramp but there is some switching going on and the settings sound different too.

Re: DT Editor
by Kupsik on 2012-12-01 09:08:34.7540

Today I've tried DT Edit and I really like it, it saved me from some quality time with MIDI-OX I hope you've going to implement loading and saving in near future so we can share our favorite amp settings with other DT users!

Re: DT Editor
by Stueyd on 2012-12-30 17:35:04.2590

Once again thanks for this!

I finally got chance to play with this some more today, main reason was that I wanted to see what it would report back about the "out of the box" settings (as i'm still having trouble getting my HD500 to nail the sounds I can get from the standalone amp so was looking for clues).

What I saw was:

I - Blackface Double Norm.

II - Brit P-75 Bright

III - Class A-30

IV - Treadplate

What suprised me was that I was expecting to see no cab models, but the A-30 and Treadplate used a 2x12 Silver Bell and4x12 Tread V-30 respectively.

Is this what other people have seen?


Re: DT Editor
by rollo69 on 2013-01-03 15:34:07.8940

Hi all,

and thanks for all the kind words.

I had some time in the last few days and so I updated the editor with a new user interface. Now it it looks a lot more pleasing to the eyes and not like an office application anymore.

<a target=new href=" class="jive-image" src=""/>

There is not much new functionality in this release as I've still haven't heard anything from Line6. But I've changed the installer to a different system to get rid of the false alarms that some virus programs created. I've never found out what they didn't like but with the new system it shouldn't happen anymore.

Re: DT Editor
by TheRealZap on 2013-01-03 15:36:32.9430

Re: DT Editor
by DropTheSun on 2013-01-03 23:30:37.3330


This is exactly, what i was wondering! I dialed a great Rectifier sound to my DT50 and wanted to make it as my main tone for Pod Hd500 and add some pedals to it too. After little tweaking, i manage to get that sound. But i had to enable Cab sim to achive the same sound. The amp settings are same in pod hd500 as they were in DT50.

I think this is how DT50 has it amps setup as default.

Re: DT Editor
by talwilkins on 2013-01-04 03:48:46.3760

Great Job! Looks really professional.

Hope you get the last missing info from line6 soon so you can finnish it.

Great value as it is right now! Thanks.

Re: DT Editor
by Kupsik on 2013-01-05 00:37:50.1660

Great look! Just one question - How does it look with loading and saving settings? It would be really nice to has this available so we can share our tones like on CustomTone ;-)

Re: DT Editor
by rollo69 on 2013-01-06 15:15:07.3150

I agree that tis would be great. Saving and loading is still in the woks but I'm having trouble to retrieve the current values from the DT reliable. So saving would currently be a hit and miss thing and this is not good.

But I'm into something. I've been experimenting with sending SysEx data to the DT lately and I've managed to get a response from my amp. I was not able to trigger a SysEx dump  yet but I''m not giving up - if the function is in there then I will find it.

Re: DT Editor

Nothing for Mac? Not your fault of course (nice application), but man, am I ever feeling like a rube...

I bought a DT25 based on how Line 6 made it sound easy to expand the capabilities. 8 amps, 4 voicings per channel with two channels - all withot having a menu on my amp. Perfect. But...not only do they not inform their dealers about which USB to MIDI interfaces work (I had to run out to buy one after the one that I ordered with the amp wouldn't work), but the 2.0 firmware, in and of itself, buys you nothing but the chance to spend more money on Line 6 hardware.

This quote from the 2.0 firmware page:

"You can also control your amp’s enhanced MIDI functionality via a Mac® or PC computer with a USB-to-MIDI interface and compatible software capable of sending MIDI CC information."

makes it seem like this is a snap. In reality, you either buy the iPhone/iPad hardware, you buy an HD500, or you have to be a MIDI expert. Or you're screwed, stuck with a 4-voicing amp that isn't versatile enough (IMO) to be worth it.

This one's probably going back. I really, REALLY don't want to do that, but my sense of basic dignity tells me I should.

Well, as a Linux user I know exactly how you are feeling. I experience the same every time I browse sites like Line6' POD HD section where people talk about HD edit and so on.

Install Windows in a virtual machine and use the edit software from there. That's the usual way the way things work if you use a OS with a negliable market share. Just get over it.

Re: DT Editor
by ivylotus on 2013-01-08 07:49:12.6650

I'm not going to. Line 6 sells the DT25 firmware V2 as though it is a simple thing to take advantage of. But it's not. And they don't provide that Windows software, so someone developing it for them in their spare time, IMO, only serves to shame them.

Re: DT Editor
by ivylotus on 2013-01-08 09:10:19.9820

Deamding everything in life is easy? Oh, come on. It's called a business arrangement. As a customer, I decide what I want to buy. They advertised the V2 firmware. I bought at DT25 based on capabilities portrayed as being easy to use, which are not (both assessments by Line 6 Tech support, who are more sympathetic than you). It's not that "I can't be bothered." It's that I purchased based on the protrayal that *they* had bothered.

I don't owe it to Line 6 to work extra hard to make their product work for me. This isn't public service. It's a product for sale. I bought it based on Line 6's website claims, which Line 6's own staff say were misleading in making it seem simpler than it is.

They can't be bothered to put in the effort that a volunteer did to make their product actually deliver their claims in a reasonably user-friendly fashion. Your fan-boy rationalization and bizarre inference that I want everything easy in life (as opposed to wanting the company I paid to deliver the ease of use they implied with the V2 release) doesn't change that.

I've worked my backside off at everything in life, from education to work to personal relationships. I'm not going to be judged lazy because I want what Line 6 *admits* they led me to believe I'd paid for.

Re: DT Editor
by evilmikehoo on 2013-01-08 09:22:32.1820

The DT's were advertized and sold for what they are BEFORE the firmware update. Awesome amps for a good price. That's what you paid for. The firmware update is just an added - free - bonus. It's for those who want to pursue, learn and use - or for those who already have the capability and ability. It's not that difficult at all. I knew absolutely nothing and was able to do it. The additional equipment needed is not very expensive and has uses other that the DT. An Uno midi / usb adapter and the Line 6 Midi mobilizer (if you don't run Windows) is all you need and both have multiple, fun, uses. The DTEdit is much better, but ya gotta find a way around Windows (still need the Uno midi/usb adapter). Good Luck - make the investment and enjoy!

Re: DT Editor
by ivylotus on 2013-01-08 09:30:13.9380

I bought after the update, which is loudly featured on the product page now. If they'd been up front and 1) Actually stated which USB/MIDI interfaces work - I had to return one, and left me already annoyed and 2) Just cut to the chase and said "this only works if you are a MIDI guy or you buy more hardware," I would have either passed or known what I was getting into. It's an annoying buzz kill the way it happened, and it makes me feel like I am geting suckered into the MIDI Mobilizer.

Re: DT Editor
by evilmikehoo on 2013-01-08 09:49:21.8720

Okay. Take a deep breath, calm down and rationalize. I can understand why you're upset, but think about the whole scenario. You got a great amp for what it is. Get the Uno Midi Sport. Do what rollo suggested. Then, download that great DTEdit program. You don't have to know ANYTHING about midi - it's extremely easy to use. Easier than most pedals, actually. As you expand your knowledege and abilities, you'll find many more uses for the UNO. Right now, you're upset and feeling burned - so yer not thinking clearly - and, like I said before, I can't really blame you. But...don't let that stop you from enjoying what ya have!!! 

Re: DT Editor

There's an absolutely wealth of help and knowledge here. I think ya just came off a li'l strong 'cuz yer upset. You want friends here.

Re: DT Editor
by ivylotus on 2013-01-08 12:09:02.0530

And you have a point about me coming on strong. But man, does Line 6 ever know how to be a huge buzz kill.

Digital modeling amps face a lot of challenges in the first place. There's the tube snobs. There's the fear that the product line is based on planned obsolescence. There are worried about reliability. And then there's unplanned but potentially inevitable obsolescence. Who would blame Line 6 for the fact that the original POD can't use the HD models? But it's a worry, because old fashioned amps are good for 50 years if well maintained. Digital has the connotation of temporary. And I don't hang them with any of this.

But why they have to - again in the words of their own tech support people - make things seem easier than they are, then bait you into buying new hardware, I just don't know.

I like to play guitar. Been playing for two decades. I work at it very hard, but I want it to be fun, not an annoying string of pointless hassles, easily avoided by just giving people reasonable information up front.

Re: DT Editor
by rollo69 on 2013-01-08 12:27:38.7340

You may try Wine. This is a kind of Windows emulator that doesn't require a Windows license. I know there is an OSX version out there.

The DT editor doesn't use any fancy Windows stuff and it doesn't need huge libraries like .NET or java. It is totally self contained. In theory it should even work out of the box with Win98 (I haven't tested this). So it should run fine with Wine as well (at least it does with Linux + Wine).

Re: DT Editor
by pauliusmm on 2013-01-08 14:09:49.6110

Maybe its a little of topic, but can someone answer: does the cab selection affects the sound that comes through speaker or only the speaker simulated output?

Also Is there any info on which feedback topology should be used for amp sims?

Re: DT Editor
by ivylotus on 2013-01-08 14:13:40.6420

I believe both, but I could be wrong.

Re: DT Editor
by pauliusmm on 2013-01-08 14:45:28.7850

If you change something in editor it is automatically saved on the amp?

So you get 8 preamps in total , but you have to pair them with only 2 poweramps right? Poweramp settings are not stored together with these presets?

Re: DT Editor
by Rowbi on 2013-01-08 15:10:36.5500

About the cab sims, here's what I know.

The default 4 amp models from the v1 DT50 all had cab sims enabled. 

Think of it like using a POD HD Pre amp model with a cab sim, and using output mode combo or stack power amp, running into the power amp input of a combo or stack. That's how the Dt amp models work.

That's often the error people make when they try to make a POD HD through a DT sound the same as the DT stand alone.... They forget to enable cab sims.

So for all the v2 amp models in the DT amps that you can enable with default settings, the cab sims are on just as the original 4 models in v1 firmware.

The cabs sims affect the whole sound, through the speaker and the direct output.

On the topic of feedback mode (and cabs too) one tip I have is to take a look at the midi info that line 6 have released with the DT v2 firmware, as I think there are settings to enable the amp model with all its defaults (inc cab model and feedback mode).  When you send that midi info to the amp it will select the default cab for that amp model (that's obvious and can be worked out which they are without needing to do this though), but for some models the feedback mode won't be obvious, so this method will help work it out.



Re: DT Editor
by TheRealZap on 2013-01-08 17:06:49.0750

all settings are "sticky" meaning yes they will be remembered... and you the power amps change as well...

select your channel and your topology... tweak to taste.... then select next... topo/channel and it will recall the previous as you left it.

Got it running under a VM. Really great software. Line 6 should have made it first. Very grateful, Rolf. Now I can see if I can get myself to like this thing despite my Line 6 anger.

I have written a Mac configuration tool. It's no way near as pretty as rollo69's dtEdit. It's my first Mac application, and it hasn't been tested extensively.

But it can configure all of the DT50 settings, and it seems to work well on my DT50 112.

As long as there is interest, I plan to give it to this group when I figure out how to package it to Apple's satisfaction.  This should be in a day or so.

So, what's the general consensus? Does anyone want it?

This would be great. With this application we will have all three major platforms covered.

Awesome. Cool that individual developers can do what Line 6 neglectd to. It really is a great amp if yiu can use it to its full potential. They owe you too a hearty thank you.

Keep up the great work. I use an HD500 and this gets me considering the 4 cable method . Great contribution to the community!

Re: DT Editor

OK, I think it's ready for release. It's my first Mac app, but I think it works pretty well. And it's a great tool to explore the DT50.  Here is what it looks like...


You can check out and modify the amp's settings, and the app keeps a copy that you can save later use.  You can even save the knob settings, if you find a combination you like.  But, you'll have to explicitly store these.

You can also generate a report that shows all the settings.  It looks like this...


The report is in Word XML format. So, you can print it with a version of Word that can read this format. Most PC versions can do this easily. But, I have had trouble doing it on a Mac. If any Mac users know how to read a Word XML format file, please let me know.

You can download the app in a zip file at this link...

EDIT: new version...

Please let me know if you find this app useful, and/or you would like to see some features added.

Can anyone confirm what the default factory cab settings are for the DT25 ?

As I posted earlier in this thread, when I used DTEditor to interrogate my amp it reported it reported cab sims on the Class A & Treadplate but not on Blackface & P75 (I actually was expecting no cab sims at all).

Check my post earlier in this discussion, as it was in response to your earlier posting.

The default settings on the DT25 and DT50, are cab sims on, and the default cab sim is the default for the amp model you pick.  So for the recto, it uses the recto cab (treadplate).  for the Park75, it uses the park cab, for the AC30, the AC30 cab, and the same for the fender.  the amp model uses its stock cab, just like when you select it on a POD HD.

You're forgetting that the peramp is modelled in DSP, and it's using the POD HD preamp models, put through a real analog tube amp (in the DT) that's reconfigured to be similar to the original amp.  If you then had cab sims off it wouldn't sound like the original, so L6 picked a speaker that worked well when using the cab sims on, but voiced for a combo or a stack cab.  i.e. the same as the output modes in a POD, combo and stack power amp output mode.  BUT if you prefer with the cab sims off, then that's cool too.  Especially if you want to use a non DT cab, and you have another cab of your own, sure the cab sims will work through anything, but if you're after a greenback sound, and you've got a nice 1970's Marshall 4x12 with original greenbacks in it... why use a cab sim of a 4x12 with greenbacks, you can turn it off and use the real thing :-)

Hopw that helps you to understand a bit more.

I have DT25, but when i hit Boost( only for DT50) on the editor- the sound changes. Why is that?

Re: DT Editor
by bmoyer on 2013-01-14 19:14:51.1120

I have noticed this too with my DT-25 but I am grateful for whatever reason the boost works.  It goes a long way towards giving the clean models some extra oomph to compete with the inherent levels of the higher gain amps.  Don't change a thang!

Re: DT Editor
by Inerzia on 2013-01-14 20:54:23.4480

Interesting... do the other supposedly-DT50-exclusive features also work for the DT25?

Re: DT Editor
by bmoyer on 2013-01-15 10:57:38.7660

Boost is the only one of the three "DT-50" features that works with a DT-25 in DT Edit  At least that's what my ears hear..

Re: DT Editor
by Steep on 2013-01-18 11:59:49.1910

Great info Rowbi!

Correct me if I'm wrong, but when using HD500 with the DT25, the preamp modelling is only in the HD500 and not through the tube preamp stage in the DT?

The only way to use the tube preamp in the DT is to connect the guitar in the input of the DT?

That's not what I anticipated from the "Dream Rig"....

Re: DT Editor
by spaceatl on 2013-01-18 12:52:47.0530

The DT amplifiers do NOT have a tube preamp stage...The 12AX7s are 100% part of the power amp...The preamp is an HD digital modeler in ALL DT amplifiers...

Re: DT Editor
by Rowbi on 2013-01-18 13:32:10.4470


Space is right, the 12ax7 in the dt25 and one of them in the dt50 are the phase inverter, which is part of the power amp.  The other 12ax7 in the dt50 adds boost for some models i think, but the main Pre amp sim is in DSP.  I assume that boost is modelled in the dt25 and POD for the models that need it, but not 100% sure.

I also am certain the boost in the dt50 isn't used when a pod is connected.  But again, I assume its not needed as any model that needs that can use DSP for it.

Re: DT Editor
by bmoyer on 2013-01-18 14:20:12.5390

I'm not understanding the fact that all settings are sticky.  In my experience, amp model, cab, class (A/B, A) boost and topology are all sticky.  But I'm finding that the drive, bass, mid, treble, presence, volume and reverb settings are not sticky.  For example if I change the drive setting on topology I and then switch to top II, the drive knob changes, but if I then go back to top I the previous drive setting I changed it to didn't stick.  At least when it comes to the setting shown in DT Edit.   Am I not doing something right?  I would love to be corrected!

Re: DT Editor
by TheRealZap on 2013-01-18 14:22:56.0230

No, you are correct... anything on a knob is WYSIWYG (what you see is what you get) and not sticky.

Re: DT Editor
by bmoyer on 2013-01-18 14:33:58.9230

Thanks Zap.  Though I was hoping I was wrong .

Re: DT Editor
by Steep on 2013-01-19 10:04:14.3870

Ok, that's informative.

So you should be able to tune in the exact same sound with the HD500 connected, as the DT25 stand alone?

You basically move the preamp modelling to the HD500 instead of the DT25, and the poweramp works the same, am I right?

That was really what I hoped for when I got both the DT25 and the HD500, because I tested the DT as stand alone, and i loved it right away.

Re: DT Editor
by Steep on 2013-01-19 10:12:32.3030

That's my experience too, bmoyer!

A sincere thank you for taking the time to develop this interface and sharing it with DT users.

I had no issues with the install (1.1.0 zip) and it is working perfectly with my DT25 head. The only "glitch" of any sort that I noticed was when I shrunk the DT Editor into the background it would occasionally switch voicings, seemed more common if I was on channel "B". Not sure if it had to do with a keystroke or something I was doing? I was using Alt/PrtSc on my laptop to copy and paste a screenshot ofthe DT Editor settings into Word so I could recall what I had set up.

Again really cool thing for you to do and thanks!

Re: DT Editor
by rollo69 on 2013-01-27 12:35:17.8960


that's really weird. I've tried to reproduce this behavior but could not make it work. A screenshot would be great. Which operating system and MIDI interface are you using?

Re: DT Editor
by itruckx on 2013-01-27 13:30:42.4830


it really saved my weekend with my 'new' DT25, thx for this editor, great. Everything worked fine with Win7 Pro 64bit. Thx for Line6, too, but a bit more support around 'the MIDI thing' or a program like this would have been fine.

So, Line6, please value the great work of rollo69 aka Rolf Meyerhoff.

Firstly, thanks for putting in the time and releasing this. I've downloaded the app and tried running it with my DT25, but i can't get the DT25 to respond to the controls. As anyone else got this to work with a DT25? Also, would you be interested in releasing the source? I'm a software engineer and I'd be happy to poke around and see if I can figure out what the problem is.



PS: Just to be clear, I'm talking about DT Customizer (beta 0.2) on Mac OS X.

Re: DT Editor
by theoptimizers on 2013-01-31 10:01:51.5800

Hi Gary,

Please use the latest version...


EDIT: Latest Version:">">


I've had a couple of people successfully connect to DT25.  Please make sure you choose the correct Midi device and channel.

Can you give me a little info...

Does the "Connect" Dialog come up?

Does it show your Midi device as a connection option?

Does it show other devices?

Are you sure you are selecting the correct Midi device and channel?



Re: DT Editor
by wattage on 2013-01-31 12:40:08.8960


I am using Windows 7 Home Premium SP1 w/MS Office Word 2007 and an M-Audio Uno with the latest drivers.

It happened one more time since, it seems to happen randomly but I am sure that's not the case. I don't know? It must be what's highlighted when I hit Alt/PrtSc that's all I can think of. I'll try to pay more attention when I am working with it.

Re: DT Editor

Hi DTers,

I've uploaded a new version. It fixes some minor bugs and the editor now recognizes the amp and it's firmware version.

My day job was really demanding in the last few weeks so I had not much time to add new stuff to the editor. But now I've got some time to spend so development will speed up again.

Hi, let me begin by saying I really apreciate what you have done.

Are you still working on the few missing (not yet working) features?

theoptimizers seems to have found out how to get it done for the Mac, iPad and even iPhone.

Maybe he will give you the needed info if you ask?

It would be really cool if your application could have the same kind of functionallity.

If you don't have the time to do it maybe other people will want to help out. I wish I could.

Rollo...nice job so far looking forward to first real release.  I was messing around a little bit this evening for about a half hour...starting gertting some undesirable and unexpected sounds coming from my DT25 so I disconnected will continue to experiment and give feedback.  Thanks for the awesome effort so far!

Re: DT Editor
by tmikeyt101 on 2013-03-24 08:17:59.0670

Rolf,  I replied a couple of days ago and had said that I was getting some weird noises from the amp so I disconnected.  Well, the noises had nothing to do with your app.  It seems the DT25 which I purchased in Nov. '12 is having tube issues already!

I'm really looking forward to a release which will allow saving and restoring presets.  That would be most excellent.  Please keep us posted.  Any idea when that may be?

Re: DT Editor
by bmoyer on 2013-03-24 08:57:24.1760

tmikey101:  I can't say it will work for everyone with weird noises, but my DT25 combo made odd noises when I would hold certain notes on the guitar and I'd hear some sort of bzzzzzz.  It didn't matter how loud the note was struck either.  Anyway, rather than take a THIRD amp back (that's right, 3) I bought a new set of Electro Harmonix tubes.  Problem solved.  I think Line6 is cutting corners on parts IMHO.

Re: DT Editor
by rollo69 on 2013-03-24 09:16:10.4450

My DT25 had exactly the same problem out of the box. But replacing the power tubes with new ones fixed the crackling sound.

@tal: as you might have guessed, lack of time is my main problem at the moment. We are in the final release phase in my day job so there currently is not room for side projects. Just after easter I'll be working again on the editor. Promised.
