Thanks for the feedback!!! Yes, agree that the pro IR's are closer to reality, but I've got plenty of reality options already. The sine sweep I am using is 20Hz-20kHz through a digital plug in. I notice a much wider frequency response than the physical cabinet IR would likely have (could be a digital-only factor). I'm sure they do a bit of post processing too that I havent tried yet. I find (as I think you did) that the Helix IR block Low Cut and High Cut and Levels really tame my IR's. I usually set low cut around 120Hz and 10kHz and set Level to personal taste. Note that the Celestion V30 spec frequency range is 70Hz-5kHz (which is close to your high setting), so setting Low/High Cut in Helix to those sounds good as well. Thanks for checking the impulse start. I don't notice any latency when playing the IR by itself or through an amp/preamp in Helix, Note that the IR's I posted are exported from Helix after Helix has processed them on Import. So maybe there is something there. I'll check into it.

New Mesa Mark III Pwr Amp + Cab IR's posted to Dropbox. I mainly made these for my Mesa Triaxis v2 Fat Mod since it has many Mark-based sounds, and I already had the Mesa Recto IR's for the built in Triaxis Recto TX4 board preamp. Also, Line 6 has no Mesa Mark models yet, so combining Helix preamps (and even amps) will get you closer to a Mesa Mark sound.

New tested workflows below!!! These IR's work great with outboard physical gear, like preamps, amps effects sends, and amps though reactive loads. Feel free to experiment as always, but the the physical components do seem to work well as you would traditionally route them in the real world. preamps sound good through Amp + Cab IR's and the amp effects sends, slaves, & reactive load outs sound good through the Cab IR's Things I have tested that work well: Helix preamps & amps (of course!) Mesa Triaxis preamp Marshall JMP-1 preamp Mesa V Twin pedal preamp Mesa Stiletto Duece II (effects send & reactive load) Mesa Mark V (effects send, slave out, & reactive load)

I have archived all previous trial IR's and files and did some housekeeping. The old stuff should still be there in the !Archive folder if there is something you think you need. All files are now at the IR folder level with a naming convention to organize them. There is generally one cab IR and one (power) Amp + Cab for each amp/cab type. I have refreshed previous cab IR's and new amp + cab IR's with updated naming so that the name in Helix is the same as the file name. It was a file title issue.

Engl Cab & Engl Pball Pwr Amp + Cab added.

You guys inspired me to create some tube power amp + cab IRs so that I could use preamp only blocks to my real tube amp and 2x12, the configure a FOH signal with a power amp + cab IR. I covered basic Marshall, Mesa, and Fender sounds. http://line6.com/support/topic/19667-power-amp-cab-irs-added/?do=findComment&comment=148050

Yeah, there is a toe switch under the the pedal, under the case metal. Activate it just like a real wah.

I have added equivalent Power Amp + Cab IR's on Dropbox along with the speaker-only IR's I previously made. These have a lot thicker sound and I believe have captured more of the tube power amp + cab interaction and vibe. These can be use with Helix preamp blocks as well as amp blocks. Using them with preamp blocks will allow you to split the signal after the Helix preamp block for a virtual effects loop or to send preamp signal to your real tube power amp or amp effects return, the run the Amp +Cab IR to the Helix XLR for front of house sound. Since Line 6 hasn't published separate Power Amp models & blocks, these Power Amp + Cab IR's will get you in the neighborhood of that functionality with a Helix preamp block. Maybe they will save Helix processing resources too with a preamp only block, who knows. These IR's should give you completely different sounds than Helix models and Ownhammer or Redwirez IR's.

Fyi, I had accidentally left the Mesa Dual Rec amp on with the Recto cab when I made the first Mesa Recto IR. I remade it again, this time with the amp on intentionally with some more recent practices. http://line6.com/support/topic/19662-at4-ir-mesa-recto-amp-cab-412-sm57-wtf-happened-version/?do=findComment&comment=148026

Haven't played guitar live with it yet, only bass. For guitar and a tube power amp/Recto 2x12 setup, preamp-only Helix blocks sound best to me. Things start getting muddier to me with full Amp blocks, and even worse when you add a cab. Heck to be honest, I would probably still let FOH mic the physical Recto 2x12 cab in a full rock band and loud venue. Alternatively, you could split the signal after all of the blocks and configure a Path 2 with the full amp and cab blocks. You would manually have to match your settings of your preamp and full amp block though :( I'm assuming Line 6 has power amp only portions of the models since they have given us preamp portions and cabs of the models. I wish they would make those available to us so we could split the signal before the power amp model, send that to our tube power amps or tube amp effects returns, then send the full amp cab signal to the Helix XLR/FOH. Then we wouldn't have to duplicate preamp settings on both a preamp only block for a stage amps, and full Amp blocks for XLR/FOH. There is already a post on idea Scale in review...can vote anymore. http://line6.ideascale.com/a/dtd/Independent-pre-and-power-amp-blocks/748793-23508#idea-tab-details

So I went back to the very first Mesa Recto IR and tried to figure out why it sounded SO different than the newer ones I was making. Turns out that I made the beginner "mistake" of not turning off the Mesa Dual Rectifier amp in Amplitube when I was just trying to IR the cab! So I have made a newer version of that first Mesa Cab+Amp IR applying some lessons learned since the first one. I think this clearer and more usable version of it. Try it with just a Cali Rectifier Preamp block too! Sounds killer. Be sure to experiment with the IR samples, low cut, and high cut. Again, a happy mistake leads to new IR possibilities. I don't know where the heck to go with this now. Helix preamps and AT power amp/cab IR's? Waters=muddied! Note that playing the IR by itself does not sound like a full amp at all. Maybe closer to a power amp and cab. It is really is its own beast. Attached the IR Mesa Recto Amp Cab_hx.wav to this post and uploaded to Dropbox. https://www.dropbox.com/sh/009bkqzooza1aop/AACk9ahjlUJzadRvQlRwGzL0a/IR/Mesa%20Recto%20V30%20SM57?dl=0 Mesa Recto Amp Cab_hx.wav

You can set the 1/4" outputs to "Instrument" in Menu>Global Settings>Ins/Outs. You'll need to press Page > once to see the setting. The default is "Line" which is usually to hot for the front instrument input of an amp. Did you try just running the Helix out into the Power Amp in of your Fender Hot Rod 2x12? I think this would be the preferred method if you are running amp models too. 1/4" outputs should be set to "line" for this method. If you do this, you might also try running Amp or Preamp only blocks, no cabs. That's what sounds best to me on my Mesa Mark V combo into the effects return, which should be the same as your power amp in on your fender.

Okay, one other thing I just noticed is that if you set your expression pedal before changing it from Decay (the first parameter) to Mix, the expression pedal assignment will stick to Decay also. Did you try to go back into Menu>Controller Assign and set Decay to None again?

If you had that issue directly in Helix and have the latest firmware, you should report that as a bug.

Ha, DI beat me by 1 minute! He's quick on the draw.

You can go into pedal edit mode (hold Mode footswitch 6 on the top right to edit), select the footswitch with IR over it, then scroll through IR's one at a time using Value + & Value -.

I love helix preamp blocks into my Mesa 2:90 power amp and Recto 2x12 cab. But that's 2U and heavy like the VHT you don't want. My Mesa 20/20 power amp sounds great too and it's 1U and much lighter. I just like to use the Deep and Modern voicing switches on the 2:90, with I can switch with Helix. You might also consider using the effects return of one of these small format, ultra light bass heads that would fit in the Helix backpack. Markbass Little Mark III is 500 watts and an analog power section. You can get them pretty cheap in the used market, but playing a bass amp for guitar might affect your "cool" factor ;) Helix sounds great into the effects returns of my Mesa M9 (big) and Mesa Walkabout (smaller) bass amps. I just remembered I have an old Crate PowerBlock that is 75Wx2 or 150W bridged. That would fit in the Helix backpack. $100 all day long for one of those. I'll try it and let you know.

Dur (me). That makes sense. AT has a different mic on each speaker, left and right. So all of my IRs are probably only getting the SM57 mic on the left side and maybe one if the room mics. Of course it would sound a little different in Helix. More adjusting and experimenting to... Combine the L & R into one mono wav Make separate IR'S for each of the L & R sides Going back to my original goal, I wanted to configure an AT cab with a Helix amp, then just IR that cab sound for helix live. I wasn't really trying to give myself hundreds of IR options and combinations. Thanks for the reply. I dunno why I didn't pick up on that...too down in the weeds to see I guess ;)

Ha, i hear ya. ...and maybe one day my MRS (a vocal performance major) will come to a show and not criticize my harmonies.

I think I understand from other posts on this forum that Helix's two processors are split between Path A and Path B, and that Path A/Processor 1 shares OS tasks/load. Path B and Processor 2 is free for blocks. I took your patches and put the IR's on the Distortion patch on Path 2, like your Clean Fender patch and noticed a very slight improvement. Maybe this is because Helix now sees the same basic processor loading between the two patches. There is still a bit of delay that is probably still not acceptable to you though based on you write ups. You might experiment more with your preset blocks with the Path and Processor info in mind.

Ok very weird. When I first tried it on a copy of the factory 01A US Double Norm preset (which uses the '63 Norm Reverb block) in the Helix app, your issue appeared just as you described. All i did in the app was simply assign Exp 2 to control Mix. It controlled the Decay level too although in the app Decay was set to None in the app Controller Assign. I also checked Helix itself and found that Mix was set to None in Controller Assign. Now here's where things get even weirder... I could not fix this in the Helix app. I disconnected the USB and fixed it right on Helix itself in Menu>Controller Assign. Funny thing is, now when I go back into Helix app, I cannot replicate the issue on that preset, the original preset, any other preset, or even a new Reverb block on a blank preset. It seems to have mysteriously worked itself out. Maybe it's a bug in the beta editor we should report. I hate that I cant replicate it now.

Uh oh, the Huge Racks (HRI) forum may get slammed with Helix rack posts soon! http://www.hugeracksinc.com/forum/viewforum.php?f=1

Ha, probably not, at least not to most. I originally took it on because there was a certain tonality and functionality of the cabs in Amplitube Cab Room that I was used to and felt like I was missing in Helix and the pro IR's. Another factor was that another member here was really on the fence about Helix because he already loved the Amplitbube sounds he loved. Finally, there was the fun in the shear challenge of it. The fact that I couldn't find anyone on forums, various customer supports, etc. that had tried it made me want to do it even more. The voices in my head were screaming that it was possible. The more I play the AT IR's I made, the Helix Cabs, and pro IR's, the more I think that the Helix Cabs and pro IR's a probably true to the original cabinets. Guitar speakers generally have a limited frequency range, just look at the spec sheets for speakers on the Celestion site. I think what I am getting with the AT IR's is the basic flavor of the modeled cab with a much wider frequency response. Which of course was just an unintentional by-product of the completely digital domain process...a happy accident if you will. But in hindsight, I bet you could achieve a similar result by slapping on a 10 band eq block in after a cab or IR block in Helix. I just like the ju-ju and mystery of a single magic cab/IR block :) I think the ability to create completely digital IR's with just DAW tools and plug-ins opens up a realm of new tonal possibilities, not limited to physical speaker cabinets. Speaking at least for myself, I think many people have really been really fixated and focused on the effort (and expense) of recreating and exactly matching the physical world in the digital domain that the potential of creating unique and equally cool and usable digital-only-based tones has been somewhat neglected. I was that person until Line 6 gave me Helix and IR blocks to play with. Line 6 is obviously open to creating their own unique tones as they do have their own amps, Electrik, Doom, and Epic...which are great! So the main point I would shout out to everyone is that, especially with Helix, you do not have to entirely accept the tones and functionality others have given you. You can make your own very unique sound print on the world. Mankind's basic functions in the world are to reproduce, consume, and create. We all create music here (I would hope), but some of us REALLY get into bending the technology to our will :D
