[???] Linux Vst: Unexpected Note-Off Events.

Help, Support & Bugs
1

Hi, I’m wondering if what I’m seeing is a bug in the Renoise VST host code. This is in the Linux build. I haven’t tried the Windows build. I’m assuming it would be fine, and Linux VST isn’t very popular, but that’s how I’m developing a synth plugin.

Have a look at the attached screen shot. So I have the two notes. When I hit space-bar, so “play”, what I get is a note-on for the C-5, the C-5 plays through, then I get a correct note-off for the C-5, a note-on for the D-5, but the D-5 should keep playing, but instead I get a note-off. So the D-5 only gets one render period, which is really just a ‘click’, and doesn’t really play. So I get something like this:

C-5 on, and many 261Hz rendering periods.
C-5 off, D-5 on, and a single render period with both C-5 and D-5 playing.
D-5 off.

Any ideas why I get the D-5 off?

You will get a D-5 off when looping back to the beginning of the pattern (the C-5 stops the D-5) or when stopping playback. Is this the issue?

I assume you’ve tested your VST in another host and it’s only Renoise which is doing this, yeah?
