ml_synth_organ_example

MIDI Organ using the ML_SynthTools library (little example arduino project)

This project is an example supporting different platforms:

ESP32
ESP8266
Seeedstudio XIAO (samd21 - cortex-m0plus)
Teensy 4.1 (imxrt1062)
Daisy Seed (cortex-m7)
Raspberry Pi Pico (rp2040)

The required library can be found here: https://github.com/marcel-licence/ML_SynthTools

All platforms are tested. Actually the sound quality might be a bit limited. The organ supports full polyphony (you can play all 64 notes of the upper manual at the same time). You can modify the sound using 9 drawbars. Percussion is supported (2nd, 3rd). A simple rotary implementation creates a simple (noisy) leslie like sound.

Demo using ESP32, ESP8266: https://youtu.be/c7TL8jcrnzs Demo using the XIAO: https://youtu.be/2wT8nByoUNw Demo using the Teensy4.1: https://youtu.be/H-NDCQnSDV0

More information will be available in future
