Holographic Psychology: Etude for Oberheim SEM filter, featuring the TEO-5
video upload by Wingo Shackleford (Mike R.)
"Stacking the raw polyphonic analog drone with thick layers of modulated reverb and distortion really brings out the singsong nature of the multimode analog 12db/oct SEM filter. You can find the sweet spots where the overtones really start to burn...
Additional FX supplied by the Old Blood Noise Endeavors Screen Violence pedal designed with Chvrches.

Cinematic Ambient w/ Prophet-10, Lyra-8, OP-1 field, norns shield | Ghost Water 2025-03-31 by atnr
video upload by atnr
"A piece created using the @SequentialLLC Prophet-10, @somasynths Lyra-8, norns shield, and @teenageengineering OP-1 field. Layers of electronic sound occasionally reveal melodies.
On the norns shield, I use DRONECASTER to generate a 283 Hz drone, which is fed into the @ChaseBlissAudio MOOD MK II for reverb and stretch effects.
The Lyra-8 produces sounds between drone and noise by pressing its keys and using feedback from the MOD DELAY.
On the OP-1 field, I perform a synth part with the CWO effect applied.
The Prophet-10 plays a sparse synth pad that mixes in noise oscillators."

"YAMAHA high-quality XG sound module MU500, we played the SMF (Standard MIDI File) of the legendary techno unit YMO. The rich tone and high expressiveness of the MU500 realize a sound that approaches the original. The swell of the synth bass, the sharp rhythm, and the glittering sequence phrases resonate as if reviving the sound of that time.Pursuing a more realistic YMO sound by fine-tuning the tone and utilizing effects. The clear and dynamic sound quality unique to the MU500 brings out the charm of the SMF data to the fullest."

Harmonic Transformer Plus
video upload by Randy Piscione
"In this video, I demonstrate the extenders for the Harmonic Transformer Eurorack module from PM Foundations. Each harmonic PCB has an SSI2131 VCO to generate the sine wave. Since this is a full-featured, very stable VCO, PM Foundations designed an easy to populate daughter card that would bring out the other functions."

"SPV-355 pitch-to-voltage synth in in very good condition. This unit allows you to route a control cv to the filter via the front panel inputs which make for more animated sequences. Decay had been modified to act also as release as on a Moog. Vital for sequencing. Otherwise the sound would stop dead when the sequencer gate ends. Cosmetically very good except for a paint flake at the top of the right rack ear."
