Prophet 600 playing by itself in a duet with piano

"I hadn't used my prophet 600 (mid 80's analog synthesizer) for a long time. When I took it out to a gig it started playing by itself, changing sounds and pitch randomly, it was quite musical I think. I sat down at the piano and improvised together with it while my friend Chris filmed.
Please do comment if someone has a technical explanation on how it could play by itself! The buttons have not been working very well for a while, I think it's something to do with the computer that scans the settings of the buttons, and also which keys are being pressed down, and this function was obviously not working as it should.
Funny thing is how it stopped at the end of this video at the same time as I stopped.
After I left it plugged in for 48 hours it has gradually come back to normal, so no more music from it.

I'm thinking that maybe one year in a flightcase was to much for it to take, so it had a lot of music inside that just had to come out.
