You're right indeed. Something's wrong.

Will try to figure it out.

How about this one:

If that fixes it we'll just swap it in the installer.

Hey Urs, I just tried the updated AUi and I can verify that it resolves the note hanging issue for me in REAPER. Thanks!

This may not be relevant any longer with 2.5.2, but I also experienced this issue with Cubase - when playing fast (many notes close together) or chords. It occurred with one specific controller, but not another. What I found using the Cubase list editor, was when playing fast notes or chords, the controller that exhibited the symptoms would send simultaneous note-off events, while the controller that worked fine would stagger the note-off events so they never occurred at quite the same time. So on my Mac, I wrote a short MidiPipe script that staggers Midi note-off events so that there is always a very slight delay between note-off events. Using this script and the controller that had caused stuck Zebra notes, the issue was corrected. Don't know if some of the note-off events are getting lost if the time-stamps are close or simultaneous? Anyway, just thought I would share this input should at some point, additional investigation occur regarding this issue.

That's extremely cool information! It's indeed possible that too close by MIDI Offs for the same note will be merged into one... hmmm...

The keyboard that sends simultaneous Midi note-off messages is a Tyros4, so pretty new. The keyboard that does not is a Fatar Studio 900, so pretty old. Here's a copy of the short MidiPipe script I wrote, that seems to help the situation by delaying note-off's by 1 millisecond:

-- Add 1 ms delay after each Note Off message
on runme(message)
-- Note message (9x status-byte on channel x)?
if (item 1 of message ≥144) and (item 1 of message ≤ 159) then
-- Off with velocity 0?
if (item 3 of message = 0) then
delay .001
end if
end if
return message
end runme

Hope that helps your investigation.

happening here too...running zebra (which i just got yesterday!) in logic 9.1.5 (os x 10.7.1).
when i look thru presets, a note will stick often. i can easily dismiss it by hitting 'bypass' on the plugin.

just mentioning (i am seriously happy with the synth)...

Working on a new MIDI queue as we speak.

Next version should be seriously better behaved re Note Off messages.

^ excellent!

I tried the demo and on some presets the notes would sustain forever.

I am thinking about buying, but would like to know if this issue been fixed yet?

When it happens, there's a quick fix.
Just change the Voice Mode setting (under the Global menu-left side) from either legato, poly, duo, or retrigger, arpeggiator, to something else.
Then change it back to the original setting.
The note sticking will stop.
As stated above. Urs said he'd fix this for the next update.
