This has been around for a while without resolve. Try this.
- press and hold a key then hold down the sustain pedal
- Let go of the key and press it down again
- Keep holding that key and release the pedal and the note stops.
The note shouldn't stop you're still holding down the key. As a pianist this drives me insane. It has been mentioned here: https://www.native-instruments.com/forum/threads/massive-x-systain-pedal-stops-note-playback.448465/
All over reddit. In posts that got resolved even though the issue wasn't fixed. It's been years and the problem still persists. This can't be a hard fix at all right?
