Fluyt - Felucca synth engines for Korg drumlogue & microKORG2

And via Regroove | RGRV on reddit:

"This is generated code, but mostly with my own code as reference (such as examples, build infra).

Don't want the FM-1 to have all the fun by themselves. Let's join them ..."

"Fluyt - Felucca's engines for logue

Felucca is an open firmware for the M-VAVE FM-1, a small synthesizer built around a JieLi pi32v2 DSP. Its sound engines are plain integer C, self-contained, and each one is a different way of 'whistling'. Fluyt takes nine of them and ships each as its own KORG drumlogue or KORG microKORG2 unit.

This is based on Felucca and associated FM-1 firmware which is mostly AI-assisted code. Personal examples, units, and build-infra code were used to create these units.

Why Fluyt?
The name is symbolic, as fluyt is a kind of Dutch vessel, mostly used for trade during the 16th century. Just like in the old days, I hope this 'trading' will happen between the communities. And, the word also means whistle."

Polly: a pocket arranger for the M-VAVE FM-1

video upload by Charles Vestal

You can find the M-VAVE FM-1 on Amazon.

"Polly is free firmware that turns the M-VAVE FM-1 into a pocket arranger, inspired by the Yamaha QY70. Play a chord, and a band of eight instruments follows it.

16 styles, each with an Intro, two grooves, fills and an Ending
Write your own chord progressions, and build songs from them, section by section
Record two melodies along the song, and fix any note in the piano roll
128 General MIDI sounds and a drum kit, with a mixer, reverb and chorus
Make your own grooves, save up to four songs, and back them up from the browser
Play from a MIDI keyboard, send MIDI to your computer, and mirror the screen

New in 0.4: melodies start as a choir, and the Ending stays in tune when you ask for it mid-song.

Install from Chrome or Edge, or try it in your browser first: https://charlesvestal.github.io/fm1-p...

Trix - 1973 Rhythm Machine Circuit Modeling (demo)

video upload by Hügelton Instruments

"Trix is a software recreation of a Japanese rhythm machine from 1973, built through hands-on analysis of an original unit and its analog circuitry.

Trix uses no samples. Every sound is generated in real time by models based on the original electronic circuits, from the resonant drum voices to the metallic percussion and noise-based sounds.

Features

• 100% synthesized
• Built-in rhythm patterns and sequencer
• Step sequencer and pattern editor
• Individual controls
• Master Tone and Over Drive
• Internal / Host / MIDI clock
• macOS AUv2 / VST3
• Windows VST3

Available for macOS (AUv2 / VST3) and Windows (VST3).

Funicular – Real-time Audio Effects for Playdate

video upload by Hügelton Instruments

"Funicular is a real-time audio effects processor for Playdate.

• Live audio input
• 3-slot DSP chain
• 14 built-in effects
• Stereo output

https://hugelton.itch.io/funicular

As Drum Machine
https://github.com/hugelton/SumaShield"



Funicular transforms Playdate into a portable real-time audio effects processor.

Connect an external audio source using a standard CTIA headset splitter, then build a chain of three DSP effects to create everything from tape wobble and vinyl coloration to delay, fuzz, filters and bit crushing.

The DSP engine is written entirely in C and processes live audio with low latency. Effects can be freely reordered, presets can be saved and recalled, and the crank provides an intuitive way to adjust parameters.

Features

Real-time audio processing

3-slot effect chain

14 built-in DSP effects

Preset management

Stereo output

Low-latency C DSP engine

Designed for Playdate OS 3.1+

Kepra - Circuit-Modeled Rhythm (demo)

video upload by Hügelton Instruments

"Kepra is a rhythm instrument developed through detailed analysis of an original Japanese vintage programmable rhythm machine.

Rather than relying on sampled sounds, Kepra recreates each instrument by studying the original analog circuits, measuring waveforms, analyzing spectral content, and reproducing their behavior in software.

Features

• Circuit-inspired drum synthesis
• 12 drum voices
• 16-step sequencer
• NOTE / FLAM / ACC layers
• 8 pattern banks
• Stereo mixer
• Drive and character section
• Internal, host, and external MIDI clock

Available for macOS (AUv2 / VST3) and Windows (VST3).

"Hardware Archaeology

Developing Kepra felt less like sampling a drum machine and more like studying an archaeological artifact.

Every instrument was investigated through circuit analysis, waveform measurements, timing analysis, and spectral comparison to better understand how the original hardware produced its sound.

Rather than reproducing recordings, Kepra attempts to reconstruct the behavior behind them.

The Missing Instrument

One voice in Kepra did not exist on the original hardware.

The Shaker was designed as an 'imaginary expansion'—a voice inspired by the architecture and character of the original instrument.

Instead of adding a modern sample-based shaker, it was developed by asking a simple question:

'If the original designers had decided to include a shaker, how might they have built it using the same technology?'

The result is not a historical reproduction, but a speculative reconstruction that aims to remain faithful to the design philosophy of the original machine.

Not an Emulator

Kepra is not intended to be a museum piece.

It is a modern rhythm instrument built from careful hardware analysis, extending the ideas of a classic Japanese drum machine into new creative territory."
