“Something else I will try is to always leave the first 8 flex and static slots empty. This way when you start a new bank all tracks should be emty (I think octa auto asigns track 1 to slot1 and so on). I will report back on this theory.”
Interesting because I realised that the first 8 slots of Flex and Statics slots are not affected by PURGE SAMPLES option. So you’re theory can be reported soon!
