Ok this one's been annoying me long enough to chime in and request some help.
In complex pro, I find if I enter envelope mode in a sample, and start messing about with the pitch envelope I find I get pops and clicks.
I've narrowed it down to creating a breakpoint on zero pitch - a click will always happen. Say if I wanted a sample to start pitching up half of the way through. I make a breakpoint at zero pitch... then another at, for example, +5. The clip will pop on that zero point.
This is definitely not just limited to one sample either, I've been working around it by adding the initial break point with a cent or two difference, leading to no pop... but that's not ideal.
I don't know if this is a bug yet but if people could chime in I'd appreciate it!
Cheers,
Joe
