Interactive MIDI in Jupyter
Project description
IpyMIDI
Interactive MIDI in Jupyter
IpyMIDI exposes the Web MIDI interface (Web MIDI API) to Python as Jupyter widgets via WEBMIDI.js. Connect your MIDI devices (e.g., keyboards, controllers, etc.) and start interacting with them in Jupyter!
Note: this is very much work in progress (nothing much to see yet)!
Usage Example
Create a Jupyter notebook and import the library.
import ipymidi
Get access to the Web MIDI interface.
midi = ipymidi.get_interface()
Enable the MIDI interface (your Web browser may ask you the permission to access it).
midi.enable()
Get the list of all connected MIDI input devices.
midi.inputs
MIDI Inputs (2)
0:
id: 92212230
name: Virtual MIDI
manufacturer: Apple Inc.
connection: open
state: connected
1:
id: -1491552641
name: Arturia KeyStep 37
manufacturer: Arturia
connection: open
state: connected
Track a specific MIDI event emitted from one input device (e.g., the "noteon" event emitted from a MIDI keyboard).
ev = midi.inputs["Arturia KeyStep 37"].track_event("noteon", ["note_identifier"])
Use the ev
object like any other Jupyter widget, e.g., to print in an output
widget the MIDI note that has just been played on the input device.
import ipywidgets
output = ipywidgets.Output()
@ev.observe
def print_message(change):
output.clear_output()
with output:
print(f"Note {change["owner"].note_identifier} played!")
output
