Not a Bug Gap with AMP+CAB+IRP channel changes

[yyz67]

This might or might not be a gapless/seamless 'bug' but want to report it in case it can be addressed or improved.

On non-turbo AF3, changing scenes with simultaneous channel changes among amp, cab, and irp blocks gives a gap while others don't. No AE or FC connected. Observed in both 23.05 and 24.b2.

The attached preset (saved under 24.b2) has 2 AMP blocks, 1 CAB and 1 IRP (w/ stereo FullRes):

• Switching between Scenes 1 and 2 (either way) results in a gap. It has simultaneous channel changes on Amp, Cab IRP
• Switching between Scenes 2 and 3 gives no gap. It has channel changes on Cab+IRP but the active amp switches between blocks.

Can someone else confirm this behavior on AF3 original? I'd also be curious if turbo version doesn't have a gap due to higher CPU.

This has been fixed for the next release.

Confirmed fixed in 24.02 beta 1. No impact on CPU.

Oops, seems not fixed now when I tried again in 25b. Perhaps I didn't correctly verify in 24.

The attached preset (saved in 25) still has a gap when changing between scenes 1 & 2 (either way). No gap between scenes 2 & 3. This is w/o AE or anything connected. CPU on my MK1/nonturbo is ~ 52%.

Can someone load and confirm on their unit (fw25)?

I forgot to mention earlier that I loaded this preset and definitely experienced the gaps.

I also couldn't seem to identify the culprit...

I tried deleting blocks copying channels, setting channels to be the same, etc.

Without either deleting everything but Input and Output or setting all blocks to the same channels, I always experienced a gap.

Full-Res (room) IRs are large and take a long time to load. Gapless switching is not supported when using Full-Res IRs.

Okay, good to know.
