Playing in HostingAU with the computer keyboard, and I'm getting hanging notes when changing parameters like waveforms, line modes etc while holding a note down with the (qerty) keyboard. And once a note hangs, it can't be silenced - even switching presets doesn't reset the notes, so you have to unload then reload VCZ to stop the hanging notes (or maybe if your host has a Panic switch it'll come in handy).
Not that this is typical usage, of course, I was just eager to give it a spin...
