Generically control MIDI devices with MIDI

MIDI Device Control

Generically control MIDI devices with other MIDI devices!

DESCRIPTION

This package sports a single method: control() which allows MIDI control of a device with a controller, as defined in a YAML configuration file.

Configuration YAML

The configuration file has four parts: The required MIDI controller and MIDI device to be controlled, an optional description, and a required list of messages. Each message can have differring keys depending on what is being controlled. These keys are as follows:

type (required) can either be note_on, note_off, control_change, program_change, or pitchwheel.

cmd (required) can be any of the above types.

note is the MIDI note number (e.g. middle c = 60) that is sensed by the controller.

control is the MIDI CC# control change number that is sensed by the controller.

target (optional) is the MIDI CC# control change number that is changed on the controlled MIDI device.

data (optional) is the value to be changed given the above target.

One of note or control must be given for note_on or control_change types.

controller: 'Arturia Keyboard'
device: 'Yamaha DX7'
description: 'MIDI control test!'
messages:
    - type: note_on # what type of message is sensed
        note: 60 # middle c does the controlling here
        cmd: control_change # the message type that is sent
        target: 14 # what parameter is to be controlled
    - type: control_change
        control: 1 # the modwheel does the controlling here
        cmd: control_change
        target: 15
        data: 64 # the value to set for CC# 15
    - type: pitchwheel
        cmd: control_change
        target: 16 # this CC changes with the pitchwheel

The controller and device must be on as MIDI ports. And these must be named exactly as they appear to the system.

Please see mido.get_output_names() and mido.get_input_names() for these known MIDI port names.

Example:

from midi_device_control import Controller
device_file = 'some-controller-some-device.yaml'
c = Controller(device_file=device_file)
c.control()
