OTTO - Your entire music-making workflow, in one box.

The OTTO is a complete hardware and software solution, with synths, a sampler, effects, sequencers, and studio modules. The interface is modal, easy to use, simple, but most of all, it encourages experimentation. The graphics are quirky, and the workflow is minimal. Yes, the OTTO is heavily inspired by the OP-1, but it is not an OP-1 clone. If you want an OP-1 you can get it here.

key-and-pad - 🎹 Fun experiment with the Web Audio API 🎶

Javascript

Key&Pad uses the Web Audio API to generate oscillators and effects. I needed some way for these nodes to be updated when the state in the Redux store changed, so I took inspiration from React and wrote a reconciler. It subscribes to the store, and whenever a change is published, it calculates the minimum change needed to update the Web Audio nodes.

DX7-Supercollider - My accurate Yamaha DX-7 clone. Programmed in Supercollider.

SuperCollider

You don't need to open the DX7.afx file. It just needs to be in the same directory as the DX7.scd. Just open the DX7.scd in Supercollider and run the big chunk of code starting from the line 35 and it's ready to use. Then run the mainCaller functions for new notes and to close notes send zero velocity from the mainCaller functions. The only requirement is to install the SC3-Plugins Ugen library because I use the FM7.ar Ugen at the heart of all operation.

klatt - derivative of the klatt 3.04 synthesizer

This is an implementation of the Klatt Cascade-Parallel Formant Speech Synthesizer. The software for this synthesizer was originally described in Klatt1980 and an updated version of the software was described in Klatt1990. The code was originally written in Fortran by Dennis Klatt. It was ported to C by John Iles and Nick Ing-Simmons upto version 3.04. The code has since been modernized and cleaned up to make it easier to build and maintain on modern C compilers and systems by Reece H. Dunn.

shaden - A modular audio synthesizer.

Shaden is a modular audio synthesizer. Patches for the synthesizer are written in a Lisp dialect. A REPL and HTTP interface is provided for interacting with the synthesizer in real-time. I started this project as a way of learning more about digital signal processing and music theory. Consider this an art project. The name "shaden" comes from the Cycle of Galand book series by Edward W. Robertson.

PySynth - Several simple music synthesizers in Python 3

Python

PySynth is a simple music synthesizer written in Python 3. The goal is not to produce many different sounds, but to have scripts that can turn ABC notation or MIDI files into a WAV file without too much tinkering. The current release of the synthesizer can only play one note at a time. (Although successive notes can overlap in PySynth B and S, but not A.) However, two output files can be mixed together to get stereo sound.
