# M5 Synth
This is a simple project I created to study some of the audio capabilities of the M5Stack devices.
## Synth Scales
> Targeted/tested device: **M5Cardputer**.
>
>`Speaker` and `Keyboard` are required.
The very first project I created for the M5Cardputer.
It's a simple demo for playing some notes (using the `Speaker`) of a particular musical scale.
- Notes can be played by pressing the 1~8 number keys on the keyboard.
- The **Key** can be changed by pressing ◂ or ▸ on the keyboard.
- Reset to the default Key (C4) by pressing esc on the keyboard.
- Major and Minor scales can be toggled by pressing M on the keyboard.
- Volume can be adjusted by pressing ▴ or ▾ on the keyboard.
## Synth Midi
> Targeted/tested device: **M5Cardputer** and **M5StickC Plus 2** (may work with **M5StickC Plus**, but has not been tested).
>
>`Speaker` (`Buzzer` for the M5StickC Plus 2), `BLE` and a Bluetooth Midi Controller required.
>
> External lib required: https://github.com/max22-/ESP32-BLE-MIDI
After creating the previous demo, I tried to create something similar but with Midi support.
It's still just a simple demo for playing some notes (and chords), but now with more flexibility.
- After booting, the program will scan for Midi controllers and automatically connect to the first one it finds.
- Press the BtnA button to toggle between sine and square wave instruments.
- Press the BtnB button (M5StickC only) to flip the screen.
- Only note on/off and volume messages have been implemented.
