"Baloran The River, in perfect technical and cosmetic condition. Lightly used in a smoke-free home studio. Includes the original manual, flight case, and a spare voice card.
This is an extremely rare analog gem, with very few units ever made. It breaks my heart to sell it, but I simply don’t have the space—it’s a big instrument!

Quasimidi Rave-o-lution 309 w/ RGB Display & Metallic Knobs
Note: Auction links are affiliate links for which the site may be compensated.

"The knobs were replaced with metallic ones, because we think they look cool.
This unit as been upgraded with the Synth and Drum expansion modules and has been given a beautiful RGB LCD. The three knobs at the front control the color and brightness. If you don't like the knobs, it would be an easy job to remove them and hardwire the color. Let us know if you want this done, prior to ordering.
The firmware is the latest known version, 3.00B"

first patch Synthetic Sound Labs Ian Fritz Hypster 5U Modular Synth
video upload by I like the Chaos.
"The Hypster is getting rate cv from a Dotcom q119 sequencer and is Frequency modulating an Ian Fritz Teezer VCO. It is also providing cv to a Steiner Filter also from SSL. The Filter is also getting cv from the sequencer. From the Filter the audio goes to a Musonics VCA turned up with no cv. I had that patcher for future plans that aren't in this video. Then to a Manecolabs Clusterverb for reverb and delay.
Very simple patch but sounds great.
This is the 5u version. NLC Nonlinear Circuits did a Eurorack version."
