fwiw, here’s what i’ve got, may be different, it’s certainly not groundbreaking but it’s useful for a single button press thru pseudo scene fade >
1 pattern, 1 track, a thru, plays free, hold/direct, track can be tempo multiplied to taste or lengthened/shortened - let’s stick with 1x 16step
the crucial thing is to try this first and vary to taste
put your ‘virtual’ scene as a plock on trig 1, plock the vanilla neutral state on step 16, now add a slide to 1
this means you can have a regular uninterrupted thru going, by either pressing Tx on the rightmost set of 8 trigs in (non record track play mode) or by pressing Tx+Play (likewise Tx+Stop to kill Thru input sound)
Now when you trig Tx on the leftmost set of 8 trigs, you play the automation from extreme through to neutral in an automated sweep, so it always exits in a neutral state, if that’s not fun enough, then plock some other steps (don’t include a slide to vanilla) and release the Track Trig (8 on left) at the scene of your liking, so in theory you can have 64 scenes to release up on, and this setting will latch until the track is played again
i’m not sure if this is what you were after, but it’s fun enough to me, quite pleased actually, for an otherwise leave-it-be thru track, so no need for extra patterns/tracks, but full control of latching/sliding fx when the mood suits, plus scenes are still available, on top ! #OTtip
