If I understand you correctly: I think I had the same issue once when I tried Native Instruments Super8 Synthesizer with one of my Midi controllers (I think it was Launchpad X). I learned that some controllers send note-off (0x80) messages and others are sending note-on (0x90) messages with velocity “0” on note end. Most instruments might understand both, but in my case it wasn’t the case for Super8.

[This](http://midibox.org/forums/topic/19471-note-off-hex-80/) might be related here, but I don’t know. Just as possible [additional context](https://forums.cockos.com/showthread.php?t=255442&highlight=Native+stuck+notes+vst3).

Edit: Probably this is also connected? [Strange sustain behaviour in Zynthian?](https://discourse.zynthian.org/t/strange-sustain-behaviour-in-zynthian/11103)
