Voice count includes purged mic positions

[d.healey]

I've noticed that if I purge a mic position the played voice count isn't affected

[Christoph Hart]

Yeah, it just does this:

return currentVoiceAmount * numChannels;

without taking into account if the channels might be purged. Thanks for spotting this, I'll need to spend more time with multi mic samples (the current project I am working on doesn't use it so I don't catch these kinds of bugs).

I think the way HISE handles multi mics is one of it's best features and I'm making good use of it

[Christoph Hart]

Alright, this is fixed.
