Topic: Prophet T8 is now a Prophet T7

Fired up the beast the other day and noticed there is no sound every eigth note. Is this a VCO (CEM3340), VCF (CEM3372) or VCA (CEM3360) issue? There seems to be absolutely no sound at all. No noise, or weirdness or crackle. Just silence. Is it possible a chip came loose while moving house?

Holla.

That certainly is possible. Open-er-up and press down on all the chips in sockets, jiggle all the ribbon connectors

Re: Prophet T8 is now a Prophet T7

Can't you make the filter self oscillate or use noise from the mixer to determine if the VCF to VCA path still works?

Re: Prophet T8 is now a Prophet T7

Never thought of that. That's why I came here.

definitely not the first time i hear about problems with dsi stuff. and people buy that crap to avoid problems with old synths breaking down. sad.

aha, i thought the T was for tabletop or something. sorry then, just ignore my hatred !

Re: Prophet T8 is now a Prophet T7

Research the "voice defeat" function for the T8. On the Prophet 600 you press record+7 while holding a bad key then all keys will play. (Thank you Dave Smith!) The T8 should have a similar function. MY P600 has 3 dead voices but I still love it. I wish the Juno 106 had this feature! This sound on sound page talks about it:

Maybe also leds will light up when the voices switch to determ where it is located.
Seems like a death vca or vco i don't believe two 3340s died at once.
Might be wice to get some spares anyway for a synth like this.

I still have to get in the studio to test but based on what I've read it's probably a dead VCA chip. The dead voice makes no sound at all. If it was a VCO apparently there should be at least noise or something.
