no real issues.  The ability to use channel B is cool but it is totally dependent on the physical knob settings on the DT so its not easy to switch back and forth but still glad to have my DT back in action...

here's an old thread on it that might help you. There's more to the thread than what I copy/pasted if you want to read more of it click the following link.

DT25 Update - error code 8000000A
by greghall on 2012-11-06 00:57:17.9270

I've tried to update my DT25 with the 2.0 firmware, but get the 8000000A error code.

I bought a new UNO midi cable, connected to my Mac Book Pro (running Lion), ran Monkey, selected MIDI device, then DT25 combo. Monkey detected the DT25 and confirmed the current firmware version. I ran Update, and got the error code.

I have the latest driver, and have tried swapping the cables around, and also doing the update from a manual download.

Does anyone have any suggestions to overcome this issue?

Just one clarification - selecting Channel B from DT25/50 section of the output block, doesn't automatically turn of the preamp/amp block in the Helix. It does let you use the DT's preamp, though.

Interesting, I will have to check that tonight.  I will have to update some snapshots if that is true...  Thanks!

yep, my experience too.  Using Helix with Channel A I can put all my post FX behind the preamp in the Helix path and use the DT power section but if I select Channel B it just turns off the preamp in my Helix and runs the whole chain into the front of the DT internal preamp/power section.  L6 Link does not insert between the DT internal preamp and power section.

Hi guys, so happy to see Line 6 has finally given us an integration solution for our DT amps and the Helix platform.  I've been a DT user since 2014 with the original Dream Rig, HD-500, DT-25HD, and JTV-69 and I love this amp.  When Helix came out I jumped on it immediately.  I posted many threads about how the DT could be used with the Helix using midi and the problems that could be encountered along the way.  The new integration isn't perfect by any means but it is an 'elegant' solution.

I've created a DT Series of Amps User Group on Facebook as a place we can gather to share our experiences and tips and tricks.  I don't mean to take away from this great forum but if you are like me and spend a lot of time on FB, I invite you to visit and join if you wish.   I've already documented how I've integrated the DT with my Helix and some of the common misconceptions about how it all works.  I would love to see what you guys can share over there too as we all learn and grow with the incredible tools we have been given.

Cheers!

In my experience, using L6 link is great but the DT internal amp modeling stays on.  What winds up happening is the Helix signal with L6 link is being applied to the front of the amp and then goes through the DT amp modeling in addition to your Helix modeling resulting in a garbage tone.  There are NO preamp tubes in the DT 25.  The sole 12AX7 is a rectifier for the power section.  The DT preamp is all HD500 amp modeling.  The best thing I found to do was to either disable the internal amp and cab modeling using something like DT-Edit or just running into the FX return of the DT.  That bypasses all the internal DT stuff but is post master so volume must be controlled from the Helix.  I see no point in trying to do 4CM with the DT because you are essentially taking a step backwards with the modelling.  My best results come when using Helix full amp models, no cab or IR, and using the DT as a fully configurable power section with a real cab.  DT is really just a great power amp.

Lucky you - I'm not a PC guy :) I'm out on the DT amp. I'm bummed to say the least. It's just too unpredictable.

Sorry to hear.  Not sure what benefit the Soleman has but you don't need it with HXFX.  The Helix midi programming capability is dead simple and more than enough for the DT.  Your issues may be related to the pass through.

Here's the link to the OSX version of DT Edit:  https://dl.dropboxusercontent.com/u/1228420/DTeditOSX.dmg

 Anyone try the editors I see posted here in the forums? Anyone have better luck with controlling their DT amp with MIDI in general?

DT Edit is a fantastic little program for editing your DT amp.  I use a $40 M-Audio UNO usb to midi adapter, no issues.  I also program midi in Helix to switch the DT and it works perfectly every time.  Dead simple to set up.  Can't speak for other controllers but the DT responds to everything I send it.

HX Effects should work perfectly in 4CM with the DT amps.  Midi is super easy to program with Helix so you can set up your HXFX patches to pull up the right amp voicing on the DT.  Remember, the DT is a 2 channel amp.  However, you can load 4 different amp/cab combinations in Path A and B for a total of 8 to choose from.  You still have to set the knobs for the 2 you plan on using on Path A and B.  If you dial in a Blackface on Path A and the use mid to switch to a Rectifier it will blow the doors off.  Best to set a clean amp on one path and a dirty on the other path.

If you have a Helix you can absolutely use the L6 link.  The problem is that even though the DT and the Helix use the same communication protocol (L6 Link), their basic software architecture is totally different and do not integrate.  They never will.  The Helix signal is actually running through the DT internal amp and cab models and that sucks.  The only solution is to also use a midi cable to connect your DT in addition to the L6 Link.  The Helix can send midi commands to the DT to control it.

I found the best way to work it is to turn off the internal amp and cab on all 4 voicings on both channel A and B in the DT using DT Edit.  I then configured the 4 voicings in channel A to Class A, topology I-IV and channel B to Class AB, topology I-IV.  Now all I have to do is send one midi command from Helix to pick the channel and voicing I want for my Helix patch.  Nothing changes in the DT.  You can use something like DT Edit to configure your DT that way.  Once you do that all the knobs on the DT are inactivated except the Master and the Reverb.  The DT is basically just a tube power amp now for my Helix.  Works great.  If you don't like it you can always do a factory reset on the DT back to normal.

Your other option is to skip the L6 Link and just go in to the DT FX return bypassing the preamp altogether.  If you don't want topology matching that might be the best choice for you.  I don't think the DT Master works that way though so the DT is full blast.  You would need to control volume from the Helix. Either way, the DT is a fantastic amp for Helix and the Helix models are a big upgrade to the HD modeling.

I'm a guitar player, not bass so... But I have the floor Helix since day one and for me, I use a lot of the I/O options for L6 link, 1/4 outs to amp, XLR to PA, FX loops to pedals.  I also use 2 additional expression pedals.  If you don't need all that for bass, and I don't think even Geddy would, you will probably be fine with the LT.  It still does everything the floor model does, just fewer I/O options really...

I have two external pedals so one is Exp2 and always volume, the other is Exp 3 and usually does mix for various effects or signal paths.  Exp 1 usually does drive or gain on amps or distortion or wah (which I very seldom use).

As much as I m lookign forward to Helix updates... I wish they are coming out with new variax hardware. Sorry for jumping topic.. but can't shut my mouth.

Not looking for new hardware but an upgraded HX version of the models would be fantastic to hook up with Helix. Better DT integration too but that would just be the cream on top...

Still better than threads about the stupid Andy Summers tone... :D

He had a tone??   lol

A big portion of the would-be-January update might be a bit... controversial. Many will love it, some will give us the ol' side eye.

so we're finally getting the Metal Zone???  lol

It is very common in the studio environment, matter of fact it is common in the studio environment to rolling everything to mono ("side level eq roll off") at around 250hz, and below. This free's up a lot of room/data in the low end that you will never hear, but gives more room for the mix to breathe. Most audio below 250hz starts to lose its directional bias, even more the further low you go. (this is why home theaters can have the sub in the corner of the room, and still have it fill the whole room) Making the stereo information in that spectrum flubby, unuseful, eating up headroom, while providing very little in the way of benefit. So it is best to just roll it off to mono.

That's an interesting concept I will have to try.  I'll put a crossover split after the IR in path 1 set to 250k and send to 2A/2B.  I'll keep the higher stuff on 2A stereo and the low stuff on 2B mono and see how it comes out...

EDIT - made this patch to explore these techniques and a few others.  Check it out if you like...

So if I get the head, should I just get the 1 or 2x12 cab, or are there other options that work just as well for a cabinet?

 

Hmmm, wonder how they sound through an L2t by L6 Link?

Any decent cab works well with them.  I built my own cabs, 1X12 and a 2X12.  You don't need to have the Line 6 cab. 

You can't run the DT head by L6 link to the L2 cabs.  The tube head MUST have a cab attached or it will fry.  You could take the cab emulated signal from the direct out to the L2T but you still need a real cab attached too.

just to add my 2 cents, someone else was asking about the template and I dug into it for them.  I wrote a whole post about it at the link below but basically it seems to have been intended to use the 1/4 to the DT FX return, not the L6 link.  That's most likely why it doesn't address the DT amp or cab modeling.  Using the FX return would bypass all that anyways.  Good points above about using cab modeling to match FOH.  Personally I don't bother with that but I understand what you are doing.  Hope this helps a bit.

http://line6.com/support/topic/27590-dt25-dt50-remote-template/?do=findComment&comment=214400

after studying the template it's really just what it says, remote switching for the DT, not any kind of integration workaround.  It's not designed to work with L6 link.

It appears they were trying to give you a 2 channel amp setup using the Deluxe in channel A and the Essex in channel B.  If you use a 1/4 out into the DT FX return and a midi connection you can use the FS's to configure channels A and B accordingly and FS 8 to switch back and forth.

The problem is where they placed the split.  It needs to move in front of the Deluxe, not after it.  The split should also be changed from a Split Y to a Split A/B and assigned to FS8.  That way when you select channel B, the signal routes 100% through the Essex to the DT channel B which you would set for Class A, topo III, and if you select channel A 100% of the signal goes through the Deluxe to the DT channel A which you would set to Class AB, topo I.

Just remember that whatever changes you make to the DT with this template are permanent until you make new ones, just like using DT Edit.  Should work fine with my suggested changes.  Going straight in to the FX return bypasses all internal modeling in the DT anyways.  However, the DT Master will be maxed out this way so keep that in mind and all volume control is in the Helix.

Why do you feel they refuse to acknowledge anything?

Not that they don't acknowledge the issues about integration or even that they are working on possible solutions.  Rather they have never once confirmed or acknowledged or even denied that the Helix signal over L6 link is applied over top of the DT's internal amp and cab modeling unless you specifically turn it off.  Not once has Line 6 ever provided those simple instructions that would have saved a lot of users a ton of  time and efforts.  My observations and workarounds have been proven to work by lots of DT users but still Line 6 hasn't ever adopted them as a simple interim fix.  Yes, the template shows how to send midi commands to control class and topology but without any guidance or instructions about turning off the internal modeling its kind of useless, tone wise.  Additionally any changes you make with midi are permanent, same as using DT Edit.  I haven't seen them mention that either.  I've corresponded with DI directly about integration issues but this subject just gets avoided.  Its like its something they don't want to admit.  Perplexing...

As far as the reasons they don't integrate, yes, DI has explained that and I totally understand.  Just weird that they haven't pushed a formal, official guide to making it work in the mean time.  Leaves room for a lot of confusion in the user base.

I never even bothered with their template since for some unknown reason they refuse to acknowledge the inherant problems trying to use the Helix with a DT amp using L6 link.  Without action on your part the Helix signal is run on top of the DT internal amp/cab modeling.  You have to turn off the DT internal amp/cvabs using midi or DT Edit.  See the link below to see how I run mine.  It works like a champ and eliminates any confusion.  Helix through DT is fantastic this way.  BTW, I much prefer full amp models over preamps and rarely, if ever, use cab models or IR's to the DT.

I still have a Dual amp patch for DT amps using L6 link on Customtone.  Check it out and see if I did something different.  Hope it works for you.  Use it as a template to build new ones.

http://line6.com/customtone/tone/1102930/

its been 2 years since I sold my HD500 for the Helix so I can't help in detail.  However, I remember having no trouble setting up dual amp tones for the DT with my POD using L6 link.  I think you may be doing something wrong.  Hopefully one of the other HD500 gurus can take it from here and guide you through the whole setup.

I have just a question:

Is it logical to connect POD HD500 via unbalanced output (1/4 jack, L or R output) to "Return" input in the rear panel of my DT25 head amp?

 

Or DT amp is designed to work with power amp section via "L6 link" only??

Absolutely use the L6 link to enjoy all the benefits of integration the way it was designed.  You could do it the other way but kind of a waste of money since you won't be making the full integration.

no like I said before, its just a 2 channel amp so all you can do is change channels or turn reverb on/off with a footswitch.  If you want to control those other functions get an HD500.  The DT was made to integrate with it.  You could also do what you want with midi if you can program it.  Unfortunately that actually changes your DT so it will remain in the last configuration you sent it for that voicing.  The HD500 does not make any permanent changes to the DT and all your settings are saved with the patch in the HD500.

Is it a Line 6 switch?  I don't understand.  The DT can only be in either A or B, there is no A/B.  I thought you meant class A or AB earlier.  Might be an incompatible FS.

Connect a Tip-Ring-Sleeve (TRS) latching, two-button footswitch for easy access to switching Reverb On and Off (Global) and switching between Channels A & B.  Alternately, connecting a Tip-Sleeve (TS) latching, single-button footswitch provides easy access to switching between Channels A & B.
