Voices management

For now when you hit a new key and there is no more free voice you just return a null in you function. You can insert a "steal note" algorithm so the first key will be off and the new key on

Good idea. I also noticed that it is problematic when hitting new keys before releasing the old one. Is there a desired priority which key should be "stolen"?

Imagine you have a 4 voices poly synth and these notes :
C2 C4 E4 G4 and you want to add the B4...the B4 must stop the first note C2 then the B4 is playing. I have solve this with the active boolean, change it to an uint8_t and write a rank on it. C2(1) C4(2) E4(3) G4(4) with the B4 the first rand is off and we decrease all the upper ranks so C4(1) E4(2) G4(3) B4(4). Let suppose now E4 is off...so we must decrease all the upper ranks: C4(1) G4(2) B4(3).
