April 30th 2025 Patch Variation #2

video upload by John L Rice

"Just exploring the patch as one tends to do. Here I’m using a second Moon Modular 569 sequencer to control the first one instead of the sequential switch I used in the previous video [posted here]. The result was simpler but still interesting to me. I also changed up the synth voice a bit, using a MegaOhm LPG instead of the SSL tube VCA and processing its output with an Oakley/Krisp1 Flanger."

Using Moon Modular Sequential Divider Switches To Control Sequencer Step Position

video upload by John L Rice

"I’ve long loved the Moon Modular 564 Sequential Switch (directly inspired by the PPG 313) and love the Moon 569 sequencer as well, but I’ve often wished that the 569 somehow had an additional row of switches that could be used to set how many clock pulses a step would stay on each position like the 564 does. This is my attempt to use two 564 switches with the 569 to make it happen, with some limitations. Of course using an external voltage controlled clock to drive the sequencer with one of the sequencer rows controlling the clock can achieve similar results, but that sort of patch isn’t as predictably playable."

"The Morphor CV/Gate sequencer is impressively powerful for its tiny 4 hp size! 🤯"

Sequencer Art II

video upload by John L Rice

"Notes suggested by Alan: C, E, F, G, Bb, C, E, F

The Chladni app used on my iPad for the visuals mimics the nodal patterns that appear on surfaces when modulated at audio frequencies. This was pioneered by Robert Hooke in the late 1600's and by Ernst Chladni in the late 1700's.

A Sunday Morning Modular Synth Patch - May 19th 2014

video upload by John L Rice

"Featuring self transposing Moon Modular 569 sequencer with 569ES and 569EG expanders and two 564 switches to vary the pattern. All clocked by an Oakley Slim VCO through a Synthetic Sound Labs V-Gates divider. The voice is a single Marienberg Sine Phase VCO into two SSL Tube VCAs, one STG Soundlabs Envelope to modular both, and the VCA outputs go to a Modcan Dual Delay 73B. And a few notes played on the Mellotron M4000D Rack. Strymon BigSky and Lexicon MX400 for reverb."

Slowly Learning The Five12 Vector Sequencer

video upload by John L Rice

"Just some baby steps as I learn to use the Vector Sequencer and integrate it into this system. The Vector Sequencer is just playing two chords and sending them via MIDI to the genXnoise dXeus machina (8 DX7’s in an 8 hp module!) and the MIDI thru goes to the Mutable Instruments Yarns which I’m selectively using to play four SynthTech based voices ."
