Hanging notes on Emulator II

Hi

I get hanging notes on some keys when I play chords on my Emulator II. By repeat pressing the key the sample stops.

Playing single keys everything is working.

I have cleaned the rubber membrane under the keys with alcohol to no avail.

What should I look for in order to repair this?

Best regards Brian

I would investigate how the E II does voice allocation. Maybe those voices that only get triggered after a certain level of polyphony is reached have an issue.
