Ah! So you’re (probably) right! I just tried it with a new kit and it hadn’t gone away after the jam. I suppose I must have had the fade set to -1 after a furious series of knob turnings
I find the FX track all kinds of inconsistent between swapping patterns with differing kits unless I trig it. I need to investigate it further at some point.
The only somewhat relevant issue I’ve ever encountered has been when using the Qperf mute/ unmute function in conjunction with using a macro to modulate the LFO fade param (to disengage/ re-engage LFO modulations – 1 fade param per LFO vs 2 depth params per LFO is more economic).
The issue: Upon unmuting, the fade doesn’t get reset for whatever reason/ requires an extra knob turn to re-engage.
