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 did GliGli's CPU and firmware upgrade (see my comment in the P5 vs P600 synth shootout thread). Many thanks, GliGli. A new beast!

Great sythns, I used two for five nights at a local bar covering fifties ,sixties,seventies and eighties etc.... Midied one to a pf-80 yamaha and the other to an m-1! Was a really fat sound and loved the organ and string patches!! Fat analog!

also, i just got a kenton pro solo mk2, and it adds some really cool features to prophet via the filter CV input. the kenton's built-in LFO is much better than the prophet's, offering some very useful LFO shapes like saw up/down and sample & hold, a much broader frequency range, and the ability to sync to MIDI. you can also use any MIDI parameter to control the filter cutoff, like velocity, aftertouch, mod wheel, expression pedal, or even MIDI CC using a MIDI controller or your DAW.

agreed with rmbls.. while it may not have envelopes that can keep up with a moog's in terms of snappiness, it is still capable of doing lots of percussive, thumping, squelchy sounds, and does plenty of other things very well. calling it unusable is a ridiculous overstatement. also, an update on an earlier comment i made - the lag i was experiencing was caused by dirt and dust in the pots confusing the CPU. opening it up and cleaning around them with a q-tip has made it very responsive and lag-free.
