Voice at 64 some notes fade out

[BWSounds]

I want to set the voice amount to my samplers and synthesizer groups to 64.
But once I do that and play chord progressions notes fade out or don't play at all..

Anyone know what I'm doing wrong, or can point me in the right direction to fix this?

@BWSounds I’ve found synthesiser groups to be unreliable with voice amounts but haven’t had time to investigate. Are you using unison?
