"So yes, it seems to work great with the original Z80 CPU, but it behaves a little strangely with the mod installed. Basically, with GliGli, oscillator pitch seems slightly erratic and janky. Sounds a little like random/noise modulation. Sometimes you can hear it on the first note you play, sometimes you can't hear it until you have played all six notes. Even weirder, this issue also goes away a bit when pitch bend is not perfectly centered. I think a multiplexer IC on the front panel PCB might be causing these problems, but since It doesn't have this issue when it's stock, I'm not so sure. I haven't messed with it. I'm including a couple replacements just in case.

I bought my GliGli mod from a pro builder on Reverb, so I don't think it was assembled/soldered together wrong. I'm pretty sure I installed it correctly as well! I'm stumped.

This synth also had a slight whine in the signal path when I first got it, but after I installed GliGli it went away and never came back, even after I reinstalled the original CPU this evening. Even when it was present, it wasn't too noticeable. (Hopefully it won't return!)

Cosmetics and other info:
This Prophet, serial number 5371, was built some time in mid-1984 and is in really beautiful cosmetic condition. A couple signs of use here and there but nothing very noticeable. Some of the lower black keys are a little dull-looking compared to the rest. Two front rubber feet were missing so I replaced them with adhesive ones. A GliGli "cheat sheet" from Synthgraphics is also now on the front panel.

All keys work!! Battery seems to be holding patches fine as well.
If you haven't had a Prophet 600 before, be aware that (when it's stock) it takes several seconds to boot up and tune each voice. This is normal!"

Sequential Circuits Prophet 600 w/ Gligli Mod

"A great synth in full working order, has the Gligli mod which greatly enhances its capabilities. Included is the original Z80 chip (Mod is not soldered so it's easy to revert to factory) and a heavy duty padded road case.

All features and controls work as they should. Even the volume knob is clean and quiet, the noise floor is really low for a synth of this era. Membrane panel looks great, some wear on wooden cheeks. There is a small cigarette mark on one key and some psychopath wrote the names of the notes on the keys and subsequently *almost* removed them, but there are still faint marks. Both of those things were like that when I got the synth around 15 years ago, don't look at me. I used it only for recording and never moved it. I will try to include those details in pics as best I can. The important thing is the synth sounds perfect."

Sonic Freakes Prophet 600 Synthesizer GliGli Presets

Published on Dec 19, 2019 Sonic Freaks

"This is a demo of the presets we have made for the Sequential Circuits Prophet 600 with the GliGli mod. In total there are 100 presets. In the 3 demo's we demonstrate ±65 of them. We hope you like them!

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."

GliGli and Behringer Announce Partnership

First Fingersonic's Luigi Scarano, then Korg's Hiroaki Nishijima, now GliGli has joined Behringer.

This one was spotted and sent in via Soviet Space Child.

“GliGli and Behringer announced today that they have entered into a collaboration to develop classic analog synthesizers.

Fabrice, aka. GliGli stated: 'Behringer reached out to me to help them bring iconic synthesizers back to life. For many years it has been my passion to create a much improved firmware for the Sequential P-600 and to design my own poly synth projects. Uli’s synthesizer Vision provides a fantastic opportunity for me to contribute to the re-imaging of some of the best synthesizer designs from the 1970’s, and to make them accessible to everyone - a Vision I profoundly believe in and want to be part of.'

GliGli continues: 'My goal with P600fw was to have the vintage polysynth of my dreams. I used my computer science and electronics knowledge to make something that was both easy to install, capable of getting the most out of the analog hardware and most of all, fun to make!'

Uli Behringer, Founder of Behringer and Music Tribe commented: 'It’s an honor to have GliGli on our team - Fabrice is an amazing synth designer and I am so proud that we could win him for our ambitious Vision.

Ever since I designed my own synthesizer in 1977, I have been passionate about synthesizers and today, Behringer is on a mission to bring back classic synthesizers as well as design completely new instruments and make them available at prices everyone can afford. We at Behringer believe that everyone should have access to the amazing synthesizers and sounds of the 70’s and 80’s.'

Uli continues: 'This partnership also demonstrates that we welcome collaborations with boutique manufacturers as we believe we can perfectly coexist and complement each other. We are currently recruiting 70 experienced synth engineers from all over the world to join us in our synthesizer mission. People interested can directly contact me at uli.behringer@musictribe.com.'”
