FreqBox Guitar Synth from Moog, Pigtronix & Mad Professor

YouTube via bigcitymusic
"We're running an electric guitar into the Moog MF-107 FreqBox, Pigtronix Attack Sustain pedal, and Mad Professor Deep Blue Delay. The dry guitar runs into the 'Audio In' on the MF-107. The 'Oscillator Out' of the MF-107 goes into the Attack Sustain's 'Audio In'. The dry guitar out (mix all the way down) of the Freqbox is running into the 'Trigger In' on the Attack Sustain. The 'Audio Out' of the Attack Sustain goes to the Deep Blue Delay, then to the amp."

Jean Michel Jarre - Oxygene Live Review

Check out the full review by mik300z at the forum.

"And just for us synth heads, there was a cs80 in his setup which he only used for a "thunder" like sound, the very same one Vangels uses in "Himalaya" from the china album. That along with a jupiter 8, ARP 2500, minimoog, some modular synths I don't know the name of, and all the other gear it was worth every penny of the ticket price just to see them!"

DIY FS3M18 Noise Generator / Filter / Synth

"The FS3M18 consists out of 3 modules that can be patched together in any way imaginable. These modules are a Digital Delay (DD) a Graphic Equalizer (GEQ) and a Distortion modeller (DM).

For example you can patch the DM to the GEQ and The GEQ to the DD.
This is the basic patch using all the modules.

When patched in a feedback loop you can still use the FS3M18 as a filter for external sounds."
