For more info visit: http://sonicfreaks.com

The Prophet 600 gligli presets collection is a custom designed set of presets which takes full advantage of the new features the gligli mod offers. The gligli mod takes the Prophet 600 into the 21st century and can easily compete sound-wise with modern synths.

In this collection you will find snappy basses and percussive sounds due to the new very fast envelop generators. The new LFO shapes enables the Prophet 600 to create beautiful evolving pad and string sounds and there are many in this collection.

The gligli mod also let you play the Prophet 600 with a velocity sensitive midi keyboard or DAW. The Prophet now becomes a very expressive synthesizer which offers a whole lot of new possibilities. A lot of the presets in this collection make use of these new expressive features.

The Prophet 600 gligli presets collection is great for every Prophet 600 gligli owner. The sounds are completely different from presets you will find anywhere online for the Prophet 600. Our presets are very modern, vintage, expressive and fun to play and to create music with. A great set of presets for creating electro, techno, synth pop, synth wave, hip hop, pop and much more."

"For your consideration is the closest you'll find to a new-old-stock Sequential Circuits Prophet 600. As you can see from the pics, the synth looks as if it was never used, and according to the original owner, it pretty much hasn't. Also included is the original box and packing foam, the original preset-cassette, and the original manual. The original receipt of purchase is inside the manual, dating to 5/25/1985.
The synth was recently serviced by Analog Synth Service in Oakland, the top Sequential tech.
It is worth noting that there are small pockets of air under the touchpad, which can be felt and/or heard, but in no way affect the functionality of the touch pad. All buttons work properly.

About the P600:
Released in 1982, the Prophet 600 is the brother of the legendary Prophet 5 synthesizer, but has its own distinct character and sound. The Prophet 600 was also the first commercial synthesizer to implement MIDI and can store up to 100 patches in memory. The Prophet 600 features 6 voices of polyphony and has 2 oscillators per voice (VCOs - saw, triangle and pulse), oscillator sync, a low pass filter, 2 envelopes for VCF and VCA, arpeggiator, sequencer, glide and poly mod functions (to create FM timbres). The Prophet 600 is a versatile and capable analog synth and it excels at drones, pads, brassy sounds and cutting leads. The Prophet 600 "Gligli" upgrade also enhances it further with snappier envelopes, more LFO waveshapes, new arpeggiator functions, unison detune and more."

Sequential Circuits Prophet~600 | By Design

Published on Nov 21, 2019 Alex Ball

"Another synth demo, this time with the Sequential Circuits Prophet~600 buddied up with its siblings.

This synth was the very first instrument released with midi (with Dave Smith of Sequential being the "father of midi"). He was later awarded a Grammy for its invention along with Ikataro Kakehashi of Roland. It was famously hooked up to a Roland Jupiter-6 at the Winter NAMM of 1983 to demonstrate that a universal protocol had been achieved.

The Prophet~600 was the third of this iconic series to be released after the Prophet~5 (1978) and Prophet~10 (1980). With their eye on affordable poly synths such as the Kory Polysix and Roland Juno-60, Sequential looked to create a cutdown version of their earlier Prophets and the 600 was the result. Around 6,000 of them were made between 1983 - 1985.

It has 6-voice polyphony with two oscillators per voice and has mixable saw, triangle and pulse available on both of those oscillators. The VCOs are identical to those found in the Prophet~5 rev3, Pro~One and Prophet~10 but the other ICs are different.

It has a resonant low pass filter, two envelopes, an LFO, poly mod, glide, oscillator sync, unison mode, patch memory, an arpeggiator and two sequencers.

And here's where things get interesting: the 600 has digitally generated envelope, LFO and glide voltages as well as digital values for the switches and potentiometers. In order to keep the cost down, an 8-bit Z80 processor and DAC were used that didn't quite have the spec to perform these functions at the speed or with the resolution that was ideal (it was 1983 after all). The result was that the envelopes weren't snappy enough and when sweeping the filter you can hear it stepping through the values.

Most owners rectify this and unlock the potential of the 600 with the GliGli mod that replaces the old processor with a modern one and also adds a bunch of features and the unit I'm using has this upgrade. We now have increased resolution, extra LFO modes, multimode envelope generation, unison detune, noise source, mix overdrive, full midi implementation and more.

In terms of physical changes, the oscillator mix potentiometer is now the Oscillator A level and the portamento the Oscillator B level. The envelope amount is now bi-polar with level 5 being the 0 volt point. The other updates are accessed via the numeric pad and speed dial whilst in manual mode.

I made all the sounds in manual mode and also used some timed automation of various parameters in places via midi.

Instruments used:
Sequential Circuits Prophet~600 (1983)
Sequential Circuits Pro~One (1981)
Sequential Circuits Drumtraks (1984)
Ibanez Jem 7DBK (2002)
Fender Blues Junior II mic'd with an SM57
Boss CE-2 (1979)"

"This weekend I finally finished repairing some dead IC chips on my old Prophet 600 analog synth. I also installed an amazing new open-source AND open hardware CPU/firmware upgrade by a French developer who goes by name "Gligli." More info here: github.com/gligli/p600fw

Here are some examples of the extreme, glitchy, grungy sounds that are now possible to coax from from this once tame polysynth!"

"Prophet 600 with GliGli mod recently professionally serviced in this last month. The Voice Boards, Main Board, and Power Supply have all been fully recapped with the Synthchaser Capacitor Kit. Other services performed include a new LED display was installed, two chips were replaced in Voices 1 and 5, all voices were tested and calibrated, new battery installed, new Audio Out jack installed, and all knobs and switches were cleaned.

In addition, a high quality ZIF socket was installed for very easy switching back and forth between the GliGli Teensy and the original CPU. This sale includes the original OS, however, in my honest opinion, the GliGli mod upgrades the sound of the P600 light years beyond what the original CPU was ever capable of. Even through good studio monitors YouTube demos do not it justice. It is truly a Nitro boost to the sound!

The combo of the GliGli upgrade, plus the full recap, calibration, and cleaning has left this Prophet 600 sounding pristine. The sound is large, deep and sophisticated. I also own a Prophet 5 and often times I just simply prefer the sound of the GliGli P600!"

"This vintage Prophet-600 is fully functional and in very good condition. This model has been recently serviced and comes with a GliGli Modification and Teensy++.

The Prophet-600 is a 6-voice polyphonic analog synthesizer with a 5-octave, 61-note (C-C) keyboard. Each voice consists of two VCOs, two VCFs, and two VCAs. Each of these components has its own independent ADSR envelope with an LFO that can modulate both oscillators at the same time, the filter frequency, and the pulse width on the oscillator. The Prophet-600 has mono mode with chord memory as well as two one-track sequencers and an arpeggiator. The sequencers are programmed in real-time and cannot be edited. The arpeggiator can be set to the normal up or down modes or can cycle through the keys in the order that they were played.

The GliGli modification adds:

Increased resolution for sound parameters
Faster, smoother amplifier and filter envelope generators
New LFO function generator with a wider range
Dedicated vibrato
Unison detune
Mix Overdrive
Full Midi In control of parameters
Improved tuning procedure"

"Is the Prophet 600 a viable alternative to the Prophet 5? We're here to find out! The Prophet 600 is about £2k cheaper than a Prophet 5 but can it make similar sounds? are they essentially the same synth, same circuits with different interface and a couple of minor differences?

Sequential Circuits Prophet 600 + GliGli Mod! SN 4540

Note: Auction links are affiliate links for which the site may be compensated.

via this auction

"Sequential Circuits Prophet 600 with GliGli mod. Here is a super-rad poly synth ( some say it is the first ever implementation of MIDI!) It's a six voice (2 osc per voice ) 100% analogue poly-synth with a dirty-raspy character. It's been described as raunchy, gritty, dirty, filthy, dark, vicious, dangerous, moody, plus it has poly-mod, an internal sequencer and serious character.

Some say it's a poor-mans Prophet 5, but I think it's more like the Prophet 5's Bad cousin breaking the law and hearts with wild abandon... but I digress. I have owned many an analogue synth and MAYBE the AX-60 comes close to having this much dirty fun, but not really. Nothing sounds like a Prophet 6 and frankly, I'm surprised that their prices have stayed so low ( what with stupid Jupiter 4's going for multiple thousands... ) anyway. The only reason I would sell this is because I have another ( which happens to have been my first synth ever ) and its just plain selfish to hold on to two of these babies.

This one is in excellent condition ( the top of one of the wooden ends lost a chunk somewhere, but that seems to be a normal battle scar for these things. ) it was recently serviced by the awesome folks at Switched On in Austin Texas. and is 100% functional and sounds devastatingly good. It has the Gli-Gli teensy mod installed ( which is amazing, look it up ) and it has a clever mod that preserves the delicate switch membranes installed as well. If you're in the market for a Prophet 600, this is the one. I promise it won't disappoint!"

Version "bon marché" et simplifié du célèbre Prophet 5, c'est le premier synthé midi de l'histoire.
Relativement limité à sa sortie en raison de son microprocesseur Z80 cadencé en 8bit, il a été remis au gout du jour grâce à la fantastique reprogrammation de son firmware par le génial Gligli. En comparaison il n'est plus très loin d'un prohet 5 pour 5 fois moins cher!"

Behringer Pro 800 vs Prophet 600 // SOUNDS ONLY

video upload by Starsky Carr

"While I'm putting the finishing touches to my full comparison video here's some sounds to demo the similarities and differences between the Behringer Pro-800 and an original vintage Prophet 600 with the GLiGLi upgrade.

Simpler tones can be copied easily as the raw tone is all there in the oscillators. The filter envelope amount, sustain and cutoff work together slightly differently than the original so adding filter envelopes makes things a little more difficult, add to that the linear envelope shapes aren't the same - GliGLi updated the linear model in 2022 to reflect a more natural Prophet 5 Rev1/2 curve but this isn't in the Behringer. Plus Behringer have made the Pro-800 snappier, so the envelopes are not going to match on every occasion... not an issue in any way, every Prophet 600 with different GliGli firmware will be slightly different I imagine too... unless everyones updated to the 2022 version.

Other differences include the Poly-Mod, filter and LFO modulation ranges aren't as wide in the Behringer"
