@DanH Dan, I found the issue here
This is becuase of The Length of Arpeggiator,
once it goes from 64 to 128, The length need to Be divided too, Or Arp wont Pick the Whole notes.
@UrsBollhalder I'm not sure scriptnode can help with this type of thing. I think it has to do with how voices are created and managed in Hise. Obviously @Christoph-Hart or someone who knows about more about C++/Juce would be able to tell us more.
Is anyone using the poly filter in a commercial product?
What am I missing? I don't see anyway to use the envelope to modulate the filter without issues. Any type of synth really needs this type of modulation.
