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.

I have a Prophet 600 I have owned since the 80's. Now the top two segments of digital display are not working. I have been looking for a schematic that would show the circuit layout. If anyone could help, I would appreciate it. Thanks

Sequntial Circuits line is owned by Wine Country Productions (of CA, I believe). If you don't know a good electrical engineer who can dianose the problem(s) try contacting them:

I used to have a 600 and they actually bought it from me for parts back in the early 1990's.

I have both the Prophet-5 and the 600. They are two different synths each with its own strengths. Overall the 600 has more cut and bite to it with an overall raspier tone than the P5. But will also do amazing strings and drones (add analog flanger and WOW!). Do a Unison stack on the 600 and its way fat and punchy. If you want dependable the 600 is the way to go, the 600 has never needed serviced other than a new battery and updated ROM. What I found most interesting is how similar the Prophet-08 sound like the 600. We recently got the Mopho in the studio and after a month of using it I could swear it’s just a modern 600. In fact many of the factory Mopho sounds are very close to the factory 600 sounds from the 80’s. I was able to quickly re-program all our 600 and some P5 sounds into the Mopho and in blind listening test cannot tell them apart. Granted the Pro 08 will go way beyond the 600 with its newer features and subs. Overall the Prophet-600 sounds great, has a unique sound.

The poor man's Prophet without a doubt. You can make this baby scream with some v. wild sounds...some which just can not be replicated on a JX, DX or AX.

The membrane keypad can get temperamental, which hinders patch saving. But you can at least do patch select via external MIDI control.

Some keys do stick, but it's fixable.

Tons o' knobs, wood panels, plus it's a Sequential Circuits!

I think the price is just gonna keep going up on these. If you see one for sale - be sure to ask about the membrane keypad, and sticky keys.
