GEOSynths Singularity Vol 3 posts

"Out Now - https://www.geosynths.com/moog-one

Back with a 3rd Volume of Patches for the fantastic Moog One, demonstrating Patches 97 to 128. The Bank contains 128 Patches, which can be either Single, Split of Layered using all 3 Synth Engines.

There's a wide range of Sounds, especially Motion and Evolving Pads, Brass and Strings, solid Bass and Leads, plus a whole host of others.

Some of the Sounds are more experimental, however they all are playable and have Controllers assigned to the Mod Wheel, Aftertouch and X/Y Pad for maximum control of how the Sound evolves over time.

There can be only One...MOOG ONE - Singularity Vol 3.

Zerosum Inertia - BFK9000 Synthesizer Processor.

video upload by NOISEBUG

"The Zerosum Inertia is a synthesizer in a pedal/desktop format that offers some very interesting processing power for external signals. Thus unit can also be used on its own with the external cv input to create melodic synth lines and odd harmonic bass lines.

In this video we play the dry signal first and then bring in the BFK9000 for crushing and processing.

via Noisebug

"Loaded with New Old Stock JAN(Joint Army Navy) stamped 6CB6 pentodes designed to meet the high quality and reliability standards of the United States Military.
Manufactured by Sylvania, Philips, Radio Corporation Of America, and General Electric in the 1960’s-1980’s.

Switchcraft jacks and Alpha potentiometers flown on wires and firmly bolted to aluminum enclosure to avoid stress applied to circuit board.

Circuit board attached to enclosure with standoffs again to reduce stress and tension being applied to circuit board.
IC's are socketed, NOT soldered directly to circuit board to make easy replacement later if/when needed.
High quality long life high temperature low impedance electrolytic capacitors from Rubycon and United Chemi-Con.
5% NP0 capacitors in the power section and audio path.
5% metalized polypropylene in the PLL sections.
1% metal film resistors.
High quality 2A/25W medical grade 12v center postive DC power adapter is included. Only use 12v DC center positive power source included.
Engraved enclosure(NO STICKER!!!!)

The BFK9000 is an effects processor designed to process audio signals from your modular synthesizer.
VCO waveforms are an ideal source.
Guitar will also produce interesting results. It is recommended that you patch your guitar into a preamp with an envelope follower before the BFK9000. Crank the gain and then patch the envelope out into the CV input of the BFK9000.
The more gain you hit the audio input with the better the PLL's will track.

The higher the frequency the better the tracking.

Try cranking the PLL frequency to max then patching the output of the BFK9000 into a divider or pitch shifter down an octave or two.
Patch LFO's, audio rate VCO's, envelopes, envelope followers, sequencers, random voltages, rhythmic pulses into the CV input.

Signal flow of the BFK9000 is 2 6CB6 pentodes providing gain to drive 2 4046 Phase Locked Loop chips behaving as primitive oscillators in parallel, but not wired up like a traditional PLL you may be familiar with.
There is some conversation going on between the 2 4046's.....Something about an alien transmission of unknown origin scrambled with intermodulation and beating.

Frequency of PLL pitch and amount of PLL influence level for each 4046, 1 set on the left and 1 set on the right.
Tube gain is maxed at full gain, no knob.
1 switch for each PLL that controls the behavior characteristics of each PLL."

MOOG MICROMOOG Synthesizer w/ Clear Backlit Front Planel

"This Micromoog had been modified with lights and a clear face plate to show off the underlying circuit board. One of my all time favorite mono-synths. The ribbon, mod wheel, everything works. It needs a tune up though, would be a good idea to get the caps replaced. Cosmetically, it is in good condition. No major dents or dings to speak of. I have the original face plate but it has a crack in it. I'm happy to take offers or questions if you have either or both."

“Fates” Monome Norns Clone

"Very little use, latest firmware, runs on Raspberry Pi 4B, faster and more memory than OG Norns. Ships with USB-C power adapter and 16gb SD card. The encoders are a little jumpy when turned quickly, and only on the PARAMS page, which I’ve learned is a common issue and can be rectified by editing the appropriate Lua file. Cheers!"

Eurorack Ring Modulators

video upload by John Schussler

"Ring modulation, according to the interwebs, is basically AM modulation (amplitude modulation) that goes through the full cycle. In AM modulation, any frequency below zero simply stops the oscillator. With ring modulation, you're still modulating the amplitude, but when the signal goes below zero volts it inverts the oscillator signal rather than stopping it. This creates a variety of new harmonics.

But those aren't necessarily 'ringing' harmonics. The ring in the name comes from the fact that most ring modulators use a "ring" of 4 diodes one into the other to create the effect.

Here's a sampling of the modules I have at the moment, doing a basic comparison of how their timbres differ. And a few have extra features that I'll try to resist playing with for sake of a fair comparison, but will probably fail in the attempt.

Sequence: Stochastic IG. VCO: Dixie II+ square (carrier) and saw (modulator). Envelope: Zadar

Dreamsynth Quick Minute

video upload by boxoftextures

"New from Cherry Audio.

Only had this a few minutes and already feel totally at home in it. Just made these three patches and wanted to get this out there so folks could get an idea of what it's about. This is the short version just to hear the patches though, the longer version will show how I built them. Might take me a day or three to get that edited though.

This thing's a winner. Three oscillators, each with dual waves with hundreds of choices, three LFOs, easy and flexible modulation and routing, sounds great. It's deep yet at the same time simple to operate. Recommended.
