@virtuscapeaudio @d-healey I think something is up with the Release Trigger Time Attenuation which makes sense with this issue.
In Logic, the clicks/pops dont happen when I hold the notes for the duration of the Time Attenuation in the instrument's HISE project.
I exported the same project without Time Attenuation checked and the issue is still there but definitely less severe.
When I try to click a node in the time attenuator it crashes HISE. I can right click to remove a node, but when I left click it crashes...Here's a screen recording of it happening a few times:
