Which uses more DSP...Cabs or IR's? VIDEO!!!

Interesting, goes against the conventional wisdom, even info from Line 6.

 

Which length of IRs did you use? Would be interesting to see how much if any difference that makes.

He must have been using 1024. If I remember, Helix doesn't even allow the placing of two 2048 IRs on one path, even with nothing else on the path. So if he used a 2048 IR, he could only have placed one IR. From the video, it looks like a Helix cab is equal to a 1024 length IR.

Exactly!!  I'm not sure why he skipped over this "little" detail.  It seems relatively important to me since I can clearly hear the difference between the 2048 and 1024 versions.

The Helix hybrid cabs use less DSP than a 2048 sample but give the same resolution. Whether or not they use as little DSP as 1024 sample IR, I don't know. They probably use a little more. I don't know that all the cabs use the same amount of DSP.

I used the 1024 IR's in the test, because that's what I use in all of my presets...to me, the 1024 IR's still sound and feel better than the stock cab/mics.

Interesting, even though you can't put any more IRs on a single path after placing one 2048 IR, you can place two more Helix cabs on. You can also put two 1024 IRs and two cabs on the same path. There seems to be rule that forces a max limit of two Helix cabs and two 1024 IRs on a path; or alternatively, one 2048 IR and two cabs. The rule not allowing two 2048 IRs may be imposed due to DSP limits but it seems to be a Helix internal rule rather than a DSP limit that does not allow for instance three cabs or three 1024 IRs on the same path.

Current max combinations of IRs/Cabs allowed on a single path

• (1) 2048 IR [You cannot add any more IRs to a path with 2048 IR] Update: I don't know whether this has changed since I first tested this in a prior firmware version or if I probably just got it wrong but initially I reported that a 1024 IR could be added to the path if it already has a 2048 IR. You cannot add an additional IR to a path using a 2048 IR in the current firmware and probably couldn't in whatever firmware version I tested this in either. I have no intention of rolling back to test this, so I am going to assume I was incorrect. You can add (1) Helix Dual cab or (2) Helix single cabs to a path with (1) 2048 IR.
• (2) 1024 IRs [a third 1024 IR is not allowed]
• (2) Helix cabs [a third Helix cab is not allowed]
• (1) 2048 IR + (2) Helix cabs
• (2) 1024 IRs + (2) Helix cabs
• One Helix Dual cab [a second Helix Dual cab is not allowed]
• (1) Helix Dual cab + (1) 2048 IR or (2)1024 IRs
