MIDI Controller

You can use MIDIController to create a new sender that will allow you to send multiple MIDI control messages at the same time, much alike a regular MIDI controller. This feature is very similar to the MIDIInstrument approach described earlier. This is an interesting approach for hardware or external software base approaches to playing Sardine:

• you can name every control change you are using instead of relying on numbers and variable names.
• you only have one interface to control multiple related messages.
• you can build yourself a library of MIDI controllers so that you don't have to do it again.

To create a new MIDIController, you will need two things:

• a mapping describing the MIDI configuration of your controller.
• a call to MIDIController to create both the sender and the player for your controller.

cmap = {
    'reverb': {'channel': 0, 'control': 20},
    'delay': {'channel': 0, 'control': 21},
}

Note that we provide both a channel and a control number for the CC we want to map. Once this is done, you can call the MIDIController function to create your new instrument. Please note that we are capturing two new names. By convention, the uppercase version is for senders while the lowercase version is for players.

Controller, controller = MIDIController(midi, channel=0, controller_map=cmap)

You can now use this new MIDI controller in each of the playing modes:

You can now use it:

Pa * controller(reverb='rand*120', delay='rand*120')
