Overview / Notes
I've been using mozzi to make a synth.
I did this: https://www.instructables.com/Arpeggiating-Synthesizer-Mosquito-I/
(code: https://github.com/analogsketchbook/mosquito_one/blob/master/mosquitoI.ino )
https://sensorium.github.io/Mozzi/
simple examples: https://sensorium.github.io/Mozzi/examples/#01.Basics
something simple:
https://sensorium.github.io/Mozzi/examples/#01.Basics
IUt was easy enough with the Arduino UNO . It has a DAC
I have a several; esp32 c3 which do not have a dac, and so I ask is a DAC requisite?
I need to learn some.
I'm reading:
https://diyelectromusic.com/2024/05/07/selecting-microcontrollers-for-music/
to to / read:

challenge: finding an Arduino with a DAC or just general mozzi support
- ESP32 originals have DAC, but not more recent more wide spread "dev" boards :(
- Teensy 3.X had DAC, but teensy 4.X , the currently available ones do not.
- my fav arduino pro mini doesn't as far as I can tell.
Maybe just bolt one on?

Arpeggiating Glitch Synth Mozzi Mod By Turbogoblin/Nugetteero
ESP32 + MCP4725
parts:
- ESP32-c3-wroom-02
- MCP4725
simple: https://sensorium.github.io/Mozzi/learn/introductory-tutorial/
so the challenge here is that mozzi support a i2s DAC, but MCP4725 is I2C dac.
google group chat with some good data
explaination about Mozzi Custom interface to external DACs or other hardware
- MCP4725 and Mozzi
steps:
1. prove that the DAC is found MCP4725
changes i2c pins:
#define I2C_SDA 5 #define I2C_SCL 4
found device at address 0x60
