I currently found out some more strange behaviour this one in the sample sequencer:

lets say I have a pattern in bankE and bankI.
each is configured like this:
pattern settings
scale mode - normal
T1 settings :
start silent - no
plays free yes
one shot yes
trig mode one
trig quant direkt

on track 1 I have a trigger on pos1 and pos3 on both patterns.
I trigger track 1 on bank E. and hear the right part played by trigger pos1 and pos3 .
when I switch to bankI, I hear trigger pos1 play the sound of part according to bankE and trigger pos3 playing the right sound of bankI.

when changing back same story vice verca
