and this one:

pattern settings
scale mode - normal
16 steps master scale
T1 settings :
start silent - no
plays free yes
one shot yes
trig mode one
trig quant direkt

lets say track one has a flex machine loaded with a sample playing a 16th length trigger on pos1.
I place a trigger on pos3 and with a paramter locked delay setting to minimum delay length maximum feedback and send.
on pos9 a standard trigger like on pos1 to reset delay params.

when the one shot finishes I get an additional " burst " of a short delay sound around the 18th note where the sequencer should have stopped by now.

I very much feel like a testing engineer not a musician…
