Help!!! I'm tired of long and double notes

[aefa]

Hello everyone,

I don't know why I keep getting sustained notes and, in odd times, double notes at the same time.
This looks pretty straight forward to me but doesn't work so.

What is it supposed to do?
1. Turn the knob and select a note stream.
2. When midi key is pressed, randomize from the note stream and play a sound (same from 0 to 3)
3. If 4 is selected or bypass is on, play the original note from keyboard.

important: when the key is released the note have to turn off, but it doesn't some times. (or goes double)
Any help... please...

Thank for any thought

Update!!!
Finally, it works!! It was a very simple thing that would, of course, drive a noob like me nuts!. After pressing the key countless times while looking at the behavior of the schematic, I noticed that sometimes the trigger would happen before the note was generated. That didn't happen in bypass mode. I wasn't too sure of the purpose of "t" on the event parameters (...please don't laugh...) but I dared myself and changed "t", on the output to 0.1 and it worked like magic!

def event i,v,t
if @nStream.length > 0
output 0, @nStream.sample.to_i,0.1
end
end

Here is the updated one.
