Introduction
BLE MIDI service for CircuitPython
Dependencies
This driver depends on:
Please ensure all dependencies are available on the CircuitPython filesystem. This is easily achieved by downloading the Adafruit library and driver bundle.
Installing from PyPI
On supported GNU/Linux systems like the Raspberry Pi, you can install the driver locally from PyPI. To install for current user:
pip3 install adafruit-circuitpython-ble-midiTo install system-wide (this may be required in some cases):
sudo pip3 install adafruit-circuitpython-ble-midiTo install in a virtual environment in your current project:
mkdir project-name && cd project-name
python3 -m venv .venv
source .venv/bin/activate
pip3 install adafruit-circuitpython-ble-midiUsage Example
"""
This example sends MIDI out. It sends NoteOn and then NoteOff with a random pitch bend.
