Giorgio Sancristoforo's Homework Now Available

You find demos in previous posts here.

Details via Giorgio Sancristoforo:

"Homework is an experimental modular standalone workstation.
A four tracks portastudio-like cassette recorder with granular, reverb, echo and saturation effects, plus two classic modular synthesizers of the 70s.

The synths integrate with the tape recorder and the effects, thanks to a generous number of patch points placed directly on the recorder panel. Homework is a powerful electronic experimental echo-system where fantasy is the only real limit and vintage warm sound is paramount!

THE EYE OF HORUS
is a modular synth carefully modelled after the west coast paradigm with some peculiar features like two Tropical Additive Synthesis Oscillators, a Hybrid Putney Filter, a Triple Variable State BP Filter, a Tropical Shaper, a Comparator and a double sequencer and clock.

Like the 1970s models which inspired it The Eye Of Horus is wild, organic and warm!

SONDA
is a modular synthesizer designed for drones, and inspired by the instrument popularized by the French composer and synthesist Eliane Radigue. Five multi-waveforms oscilaltors, two multi-mode variable state filters/resonators, two modulators/amplifiers, one LPF 24 dB filter, a 7 channel mixer and a special very slow triple low frequency oscillator.

Available for Mac OS (M processors suggested) at giorgiosancristoforo.net"

"This module introduces a unique approach to rhythm, it can add complexity to any pattern by superimposing extremely odd divisions creating syncopation and rhythmic complexity. It provides extensive possibilities for rhythmic creation, transforming static rhythmic patterns into dynamic and complex rhythmic layering enhancing the rhythmic foundation set by the primary clock. It allows users to explore and generate rhythms in previously unattainable ways.

The module operates by taking an input clock signal and generating two new independent outputs that dynamically accelerates or decelerates the BPM toward a user-defined destination BPM over a specified number of beats. Meaning that the output generation is never constant, they will always be dynamically accelerating or decelerating, where no interval between two pulses is the same, the current interval will always be shorter or longer than the previous interval.

This principle will generate unique metrics that when played against the main clock will create extremely unique patterns, from simple swing /syncopation to beyond free-jazz completely unexpected while mathematically justified metrics.

Introducing the Body Synths Laboratory

video upload by Body Synths



"The Body Synths Laboratory is a dual-channel effects processor and feedback synthesizer.

Four feedback paths sit at the core of the Laboratory. Route signals, control delay repeats, or add gritty textures. Push them far enough, and the system enters self-oscillation—even with no input. From there, every control reshapes the feedback into anything from subtle drones to harsh noise madness.

Each channel features three voltage-controlled effects: gain, delay, and filter. Run the channels in series or in parallel. Push signals from silence to amplification with the Gain control. Drive the Delay into dirty territory at longer times—we’ve used that famous karaoke machine delay chip. Combine both channels to create multi-tap or ping-pong echoes.

The Resonant Filter provides Low-Pass and High-Pass modes. Chain the two channels in series to create Band-Pass responses. A final clipping stage at the end of each channel adds compression and distortion when driven to extremes.

We’ve also included a global Modulator that can operate as either an Envelope or an LFO, with two positive and two negative CV outputs. Patch them to build effects like tremolo, vibrato, chorus, moving stereo filter sweeps, modulated delays—it can get pretty wild.

The Body Synths Laboratory is being developed in collaboration with Andrey from the Berlin-based pedal company akkusativ.

Release: 2026. Price: TBA."

Patching Exciting Modulation for Filters // FIRST PATCH with Swell from Bartola Instruments

video upload by DivKid

"Here we have the new Swell Eurorack filter and valve gain stage from Bartola Instruments. We'll be exploring this in the usual in depth DivKid demo style in the future but wanted to share our literal first patch playing around with saturating, character oozing valve distortion and filtering ... and in doing so, share some modulation tips about how we like to patch modulation, mixing sources and making things feel exciting and dynamic. I hope the patch notes below are useful and let us know what you'd like to see more of with Swell."

"*PATCH NOTES*

The simple bit first - AUDIO PATH - two saw wave oscillators, changing the octaves between them at points, mixed into 'Swell' and then output into some stereo FX for background ambience.

The modulation is where this gets exciting going into the FM input (which modules filter cut off frequency) is my main envelope, a simple decay envelope. Resonance is modulated by a step sequence (external attenuation is the key here). Then the v/oct input is used as a place to input a mix of modulation. The first is an accent envelope, patching a less dense gate rhythm into a second envelope and patching that into a mixer. Then outputting the mixer into the v/oct input of the filter. The second is then the same step sequence as the resonance.

So with the mixer into the v/oct and the FM input I have 3 modulation sources modulating the filter frequency - main envelope, accent envelope & step sequence.

Modules used - Thonk Synth VCO, Joranalogue Cycle 5, TINRS Next Tuesday, Making Sound Machines Multiplikand, Bartola Instruments Swell, WMD + Infrasonic Audio Cosmis Debris, Vostok Instruments Fuji, Apollo View IOU, Thonk Synth dual VCA.

Bob Moog's First Keyboard Instrument Ever Built Added to BMF Archives

via The Bob Moog Foundation

Meet The RENSITRON!

"Bob Moog's First Keyboard Instrument Added to the Bob Moog Foundation Archives

Bob Moog’s earliest known keyboard instrument, the Rensitron, now resides in the Bob Moog Foundation Archives! Bob built this small electronic organ in 1951, at only 16 years of age. His Bronx High School of Science teacher, Hymen Rensin, bought the instrument from Bob for $10 ($120 when adjusted for inflation)!

The Rensitron is a two-octave electronic organ, featuring vacuum tubes, hand-carved wooden mini-keys, and a built-in 5-inch speaker with a hand-made, stylized 'R' speaker grille, all encased in a slanted wooden cabinet. If you're wondering how someone so young could have designed this, Bob had already been dabbling in electronics since age ten! The 'chicken head' knobs on the front panel for volume, tone, and pitch are the same as those used on classic R.A. Moog synth modules, whispering hints about the world-changing instruments yet to come. Similarly portentous are two top panel labels, which read 'Rensitron' and 'Electronic Organ Made For Mr. Rensin By Robert Moog May 1951,' both of which use the same black Dymo Labeler tape as the early R.A. Moog modular systems.

Most notable up top are hand-crafted wooden keys with spring action, most likely made by Bob's father, George Conrad Moog, an engineer and woodworker. Some of the keys have less 'spring in their step' than others, but most still retain a very playable feel!

To learn more about the Rensitron and see more pictures, check out our blog post on moogfoundation.org!"

"An improvised deep-dive into the harmonic chaos of the Montreal Assembly PURPLL.

While many know the PURPLL as a PLL-based dirt box, it hides a massive drone synth within its circuitry. In this session, I’m utilizing its internal pulse wave oscillator, utilizing the multiply and divide channels to stack overtones and subharmonics into a wall of sound.

The signal is shaped by the onboard filters and modulated via LFO before hitting the Universal Audio UAFX duo for spatial depth.
