Tempo /BPM parameter

Not really with existing features.
You would need to track the state for each note in your script and toggle.

Just saw that you got a reply elsewhere. Linking:

“Toggle” mode for note playback?

Hello, Is there a built-in parameter or functionality in HALion to enable a “toggle” mode for note playback? Specifically, I would like a note to behave as follows: When I press and release the note, the loop continues to play. If I press the same note again, the loop stops. Is this possible using HALion’s existing features, or would it require scripting? I have looked inside HALion and in the manual but I can’t find it. Thank you!
