CPU load stays high untill double pressing STOP

Hi MPC-people,

I've bought me an MPC-X to use for live performance, bringing progressive/techno.

On my first try I ran into the low RAM limiting the length of my set when using many different long multi-sample keygroup programs. I've overcome that part by using very short samples and chip tunes to merely use the sampler as a synth. I've even got the very basic sines, square and saw forms that provide a lot of possibilities with limited space. Great! So far ..

However, now on round 2, I run into high CPU usage after running just a few (effect heavy) sequences. And it stays high, even after pressing STOP once. Only after double pressing STOP, CPU drops. Funny thing it though, that running a single sequence only requires up to 20% CPU. So these lingering processes (I don't know what they are) - that don't even produce sound anymore - keep the CPU running high and I can't kill them without killing the live performance and double press STOP. That's a buzzkill.

Does anybody know a way to stop these lingering processes and bring down CPU without double pressing STOP?

Does this maybe have to do with the fact that the tail of the heavy effects you are using are causing this...keeping the processor up...?!?

Normally a double stop will cut short all processes running (like stopping a long sample)...so this is normal behaviour of an MPC.
