Hi everyone. I've been playing with samplerbox and when using a velocity layered library at about 200meg, the performance time is about ~30 minutes. Around 20+ minutes artifacts begin of static pops, delayed note triggers, and cutting off of samples, eventually to the point of unplayable. Anyone else experiencing this? What is the longest non stop performance time you have got out of it? Post below your times and hardware.

Strange behaviour! Have you tried a combination of things? eg different sample sets, different audio interface etc?

I've had mine running overnight before - played it in the morning and all was fine!

could be the number of notes played? will try with my drums to see if it ever happens.

@Nathan - try lowering MAX_POLYPHONY to something like 20 in your samplerbox.py script. I encountered a memory leak issue which shares the same symptoms as your problem
