Helix: Dealing with the awful clunks and jumps between snapshots

I've seen a lot of videos showing the jumps and spikes during the snapshot switching period (which somewhat negates the advantage of snapshot switching time vs switching presets). I have seen it said that it has to do with the order that things switch in and out and change on the snapshots.

Has anyone figured a good strategy for making the snapshot switching overlap time smoother?

I am thinking of creating some separate presets with Preset Spillover on and seeing if I can get the parameters figured correctly there and then somehow maybe translate it back into the snapshots

Yes that's the point. If for example you have the snapshot A with the amp level 5 and drive 10 and the other snapshot B with amp level 10 and drive 5, and let's say for example that they have the same perceived volume. But when you change snapshot from A to B the sequence of changes is first the amp level and then the other blocks/parameters: for a few milliseconds you will have amp level 10 and drive 10, and you will hear a big volume spike.
So the strategy is to try to change the volume levels using other blocks or other parameters.
Unfortunately I don't know what is the sequence of priorities during the snapshot change. If I'm not mistaken, once Mr Igor Stolarsky (system engineer at Line6) wrote something about this in a comment in Facebook, but I don't remember the information and I can't find it anymore.
 
It has to do with gain and amp levels. I had the same problem. Bring the snaps a little closer with those two fields and it will disappear.

UpsideDownGuitarGuy:

I'm trying to build a preset around the Rockerverb because I freakin love this amp. I am just trying to go from clean to distorted, but the drive parameter change seems to always cause a loud pop, even though the volumes are matched. Does anyone have a solution?

Are you also bypassing any blocks with the snapshot and using a param change to adjust the volume? Snapshots process bypasses first, then controllers (i.e. param changes). So if you bypass/enable something that changes your level, then adjust the volume param on something to compensate, you'll hear a little blip of the sound before the param change happens, which frequently sounds like a pop.

Gain stage all your blocks so that they're more or less at the same volume when they're enabled or disabled (an exception might be a drive pedal boosting level INTO an amp) and it should go away.
 
I gave preset spillover a try, and it was pretty neat, but damn, it switches so slow that I'd rather have the clunk...So now I'm trying to make sure the levels of the bypassed/unbypassed stuff is similar, so hopefully I can get rid of the worst of it.

I doubt that's the only cause. I had a preset where nothing changed but the IR. From one OH to another. Nothing else. Gain the same, volume the same.
Still got a loud POP.
 
I think this click/pop is audible when there is a sudden cut in the waveform and big gain difference involved, like switching between two amp models in series on the same DSP path.
 
I must be lucky because I’ve never had that problem.

IMO changing IRs should have been left out of snapshots, because that one will obviously have a gap or pop. You’re basically changing gear like if you were switching from one OD to another or something. I can’t imagine a scenario live where this would be necessary anyways, but everyone uses the gear differently. There’s a gap when you cycle through IRs anyways, so I would expect the behavior to be the same when you control that parameter with a snapshot.

Let's play some "WILL IT POP?":
can you do a test and assign the same IR swap to a Footswitch as controller instead of a Snapshot?
