Sequential Circuits Prophet 600

Sequential Circuits Prophet 600 Image

The first commercially available synth to implement MIDI!! It's a fun synth. Its big brother is the legendary Prophet 5. The P600 is very affordable today and is a great buy. Models with the newest software will enjoy polyphonic MIDI implementation and up to 100 memory patches to store their own sounds! The sound of the Prophet 600 is brighter and harsher than that of a Juno 106 but still just as funky.

The P600 has two oscillators per voice with sawtooth, triangle and variable pulse waveforms. The oscillators can be individually tuned or synced together. Similar quality VCF and VCA sections from the Prophet 5 can be found here too! The P5's Poly-Mod section has also been passed onto the P600.

The P600 is extremely versatile and easy to use! Its best functions include the onboard arpeggiator, 2-track sequencer and poly-modulation. The P600 is great for creating analog effects, swells and drones. It has a cool glide effect and has very flexible modulation possibilities! It is used by Hardfloor, The Higher Intelligence Agency and Eat Static. Perfect for Ambient, Dub and other electronic music.

Prophet 600 dude

I have a Prophet 600 which is missing the flat numpad keys/ribbon cable on the left side. The knob and the 7-segment LED display are there. It seems to power up sometimes, but doesn't make sound; I haven't gone through and cleaned it because I'm not sure if it will function without the flat, square numpad part with the ribbon cable.
Anyone know if it will work without it? If not, where can one be bought--or is there a DIY replacement? Email me at if you know, thanks in advance!

To all the folks saying their p600 no longer works, squeaks and some dead notes CLEAN ALL THE POTS AND SLIDERS WOTH PROPER ELECTRICAL SWITCH CLEANING SPRAY AND RESEAT ALL THE RIBBON CABLES INSIDE. Audio signal is routed through those pots so if sound is going crusty and staticky then you will notice a massive improvement by cleaning those pots, knobs, sliders, switches .

Had mine since 1983 - I think! Actually my first one was bought at Dougies music in Cheshire UK, and they got burgled before I picked it up and some twat stole it. Dougie replaced it with another and it had better midi version (upgrade). I've had it forever and it has worked well up until 10 years ago(!!!). It went crazy and would not program or play. So I took it apart and cleaned all lots and switches and connectors on the boards. Fixed and good as new. If yours has gone mental clean the hell out of the pits and switches and reseat those ribbon cables and you should be fine.

Unstable, too harsh sound for my taste, envelopes not only slow but with strange/unmusical shapes for attack and release specially, I found it a bit frustrating...
