Problem with new Prophet 12 Keybed?
« on: May 20, 2026, 02:49:53 PM »
Hey There,

I have contacted support but thought I would also post here in case somebody might have any ideas.

I was lucky to get a brand new Prophet 12 off ebay (It was new in Box, still has screen and key potectors on).

However upon powering it on it was clear there is an issue.

Some of the keys (mainly in the higher octave) seem to have either a delay or the voice does not sound at all.  It seems the lower velocity is played, the longer delay until I hear the voice.  Sometimes it does not sound at all.  Some keys appear to be more affected than others.

I have powercycled the unit and this appears to happen with all sounds (including init patch).  Hoping it might be a simple fix such as opening the unit and checking all the keybed connections, but I would be interested to hear if anybody has had any experiences like this?
