Kesako & Rhythm Ace FR8-L

"Modified Ace Tone 'Rhythm Ace FR8-L' coupled with a Kesako 'Player'. Reconnecting my pin matrix and jamming.

I'm using the pin matrix prototype I made for the Mos-lab 2500 with the FR8-L = 10 instruments are connected to the matrix and 30 different clock combinations."

Mos-lab 2500 - 1036 Random

video uploads by batchas

"One 1004-P VCO sent to one 1006 Filter/VCA.
I’m using the 1036 S&H clock output to clock the 1027 Sequencer and to gate the 1046 Env. Generator.
I added a small external circuit to be able to do that, transforming a trig into a gate, cause the clock signal of the 1036 is a trig, not sufficient to trig an envelope for instance.
On this external circuit I’m also adding the possibility to use the 1027 main clock while set to external mode. Knowing that in external mode, the clock out of the 1027 is deactivated. Meaning I can have 2 extra clock signals (normal and also inverted to clock between steps) while the pulse width of the 1027 clock is been modulated."

Moog muSonics Sonic V Demo video upload by MOS-LAB

"The sonic V is a synth developed around 1969/1970 by ex Moog employee Gene Zumcheck (the idea of a portable synthesizer had been refused at the time by Robert Moog).
This synthesizer was built by the company muSonics when Gene Zumchek join them, and was released "officially" when the company bought R.A Moog in 1971 under the Moog muSonics badge.
There were less than a hundred units built (mine has serial number 18).
Unfortunately, very few models are still in existence today, making it a very rare instrument. Not having been exported at the time, it was mainly
intended for universities in USA.
Its successor, the Sonic 6 is an improved and portable
version, but with a different filter (Moog ladder filter)
So it doesn't sound quite the same."

Spotted the above video in the listing below. I'm not finding it previously posted so up it goes. You can find additional demos in previous posts.

Do You Suffer From SSSS? (Sticky Sequencer Switch Syndrome)

video upload by John L Rice

"Several brands of modular synths, including Moog, Synthesizers.com, Moon Modular, Club Of The Knobs, Mos-Lab, Synth-Werk, etc. use a particular style of momentary push button switch in their sequencer modules that can sometimes bind and stick, which is annoying to unacceptable. I don’t know if all of these switches are made by the Switchcraft company or some are knockoffs? Anyways, this video shows how bad the switches can sometimes be and shows some possible solutions."

"This is the second patch on the system.
A pity I didn't take care while recording, cause the recorded sound, its middle and bass frequencies components, is far to be true compared to the sound in the studio. I'm always too spontaneous when starting a session or a patch. I'll take better care for the next session, cause it's a shame when not accurate."

The Vanishing Night

video upload by davidryle

"Good things happen in pairs sometimes...

Two new Synthetic Sound Labs 1201 TZ-VC Oscillators are the main project center. I sent the lower tuned sine wave (modulator) to the higher tuned (carrier) phase modulation input. I routed the modifier through a vca with a random S&H amount to give it a little life.The modulator was pitch tracked from one of a pair of Matrix Algorithmic Composer modules from SSL. The carrier was pitch stable. The wave of the carrier is a triangle wave through the Grove Audio G294A LPF. It is the final tuned percussive sound trailing at the end with the drone.
The other paired oscillators were the drone duet played by the STG Soundlabs vco's through a Q107 SVF in low pass. The pair of STG VMS sequencers are the pitch source.
The bass part is a trio of Mos-Lab 901's and an SSL 1200 vco. They are low pass filtered with the LWSS M401 Multimode Filter/Resonator. The upper Q960 step sequencer is the pitch source.
The opening synthetic pan drum sound is a Q106 saw wave and the square wave output of the second Matrix module run through the Oakley Ring Modulator and a Q150 LPF. The Q106 is pitch controlled by taking the Matrix cv through a quantizer and then a S&H to limit the cv range.
The second percussive voice was the PWM output of the modulator 1201 through a Mega Ohm Audio MA20 vcf in high pass then a EHX Grand Canyon reverb and finally stereo phase shifters from the Lexicon MX200.
Snare sound is the SSL Woven Spirits (MI Plaits) and the Kick is the Delptronics LDB-2e. Percussive timings are handled by the Moon Modular 563 Trigger Sequencer.
The drone loop arpeggio is the Dove Audio D900 Mu-Seq into a Q106 saw wave to an EHX Canyon pedal in multi-tapped delay mode."

MOS-LAB Kobol Expander III RSF SN 3561

via this auction

"A stunning recreation of the RFS Kobol Expander synth, made by the genius company MOS-LAB. Everyone who used this along the original RSF Kobol side by side says they sound absolutely spot on. There's on Kobol Expander being sold at 10K on Reverb right now... This one is even more rare, as only about 30 were ever made.

Super snappy, big bass and morphable waveforms. Since the waveform morphing is made with a discrete waveshaper, the volume isn't consistent during the sweep. The original responds like this, too, but it got me by surprise so I'm mentioning it, so that you don't have to do your research ;-) The filter is super smooth and liquidy.

The synth comes in a Moon Modular rack, with a standard PSU."
