MIDITONES ~ MIDI To Simple Bitstream Conversion

Posted by tom2tec on 

MIDITONES: Convert a MIDI file into a simple bytestream of notes.

MIDITONES compiles a MIDI music file into a much simplified compact time-ordered stream of commands, so that the music can easily be played on a small microcontroller-based synthesizer that has only simple tone generators. This is on github at www.github.com/LenShustek/miditones.

Volume ("velocity") and instrument information in the MIDI file can either be discarded or kept. All the tracks are processed and merged into a single time-ordered stream of "note on", "note off", "change instrument" and "delay" commands.

MIDITONES was written for the "Playtune" series of Arduino and Teensy microcontroller software synthesizers.

Deej ~ Hardware Volume Mixer

Posted by tom2tec on

deej is an open-source hardware volume mixer for Windows and Linux PCs. It lets you use real-life sliders (like a DJ!) to seamlessly control the volumes of different apps (such as your music player, the game you’re playing and your voice chat session) without having to stop what you’re doing.

Posted by tom2tec on

This library is made to be used for synthesizer projects. It contains modules to create sound, to drive an audio codec and create some audio effects.

This library supports different platforms:

  • ESP32, ESP32S2, ESP32S3
  • ESP8266
  • Seeedstudio XIAO (samd21 – cortex-m0plus)
  • Teensy 4.1 (imxrt1062)
  • Daisy Seed (cortex-m7)
  • Raspberry Pi Pico (rp2040)
  • STM32F407 (cortex-m4)

AcidBox ~ DIY Hardware Synthesizer

Posted by tom2tec on

ESP32 headless acid combo of tb303 + tb303 + tr808 like synths. Filter cutoff, reso, env mod, accent, wavefolder, overdrive within each 303, per-instrument tunings, hi-pass/lo-pass filter and bitcrusher in drums, send to reverb, delay and master compression. All MIDI driven. 44100, 16bit stereo I2S output to the external DAC or 8bit to the built-in DAC. No indication. Uses both cores of ESP32. Cheap ~$10. Consult with midi_config.h to find out and to set up MIDI continuous control messages.
