EVENT_PAR_ZONE_ID differs with duration in play_note

I want to know if a note has a zone attached to it. So I used EVENT_PAR_ZONE_ID but I get different results depending on the duration value in the note_on function.

Code:

ev := play_note(EVENT_NOTE, EVENT_VELOCITY, 0, -1)
wait(1)
message(get_event_par(ev, EVENT_PAR_ZONE_ID)) // prints -1

This returns -1 if I play notes with no zones attached. This is how I thought things should work.

Code:

ev := play_note(EVENT_NOTE, EVENT_VELOCITY, 0, 0)
wait(1)
message(get_event_par(ev, EVENT_PAR_ZONE_ID)) // prints 0

This returns 0 if I play notes with no zones attached.

Is this by design? Or am I missing something again?

 

You need to wait(1) before grabbing the zone ID.

 

I did. it's just a snippet of the code ... edited the post to reflect this.

 

If you don't have any zones in the instrument then there's no zone ID to return!

 

Yes, it should return -1. But it returns 0 (the first available zone in the group) if the duration ist set to 0 in the play_note function ...

 

Curious. No idea - first time I see that!
