How does the voice stealing algorithm is working in the WAV trigger?

What happen if I already have 14 voices running and I try to play another voice before any voice of the 14 that already running is finished?

Thanks

It defaults to the first voice called to be called being stopped, and the new (‘15th’) voice overwriting it in memory - but you can prevent this by ‘locking’ the voice(s)
