DAW Setup

macOS Setup (IAC Driver)

Enable IAC Driver

1. Open Audio MIDI Setup (Applications > Utilities)
2. Menu: Window > Show MIDI Studio (or Cmd+2)
3. Double-click IAC Driver
4. Check Device is online
5. Ensure at least one port exists (default: “Bus 1”)
6. Click Apply

Verify Connection

resonon --list-ports

You should see “IAC Driver Bus 1” (or similar).

Windows Setup (loopMIDI)

1. Install loopMIDI
2. Create a virtual port (e.g., “loopMIDI Port”)
3. Connect in Resonon:

midi_connect("loopMIDI Port");

Or via CLI:

resonon -p "loopMIDI"

Linux Setup

Use ALSA or JACK virtual MIDI:

# List available ports
resonon --list-ports

# Connect
resonon -p "Your Port Name"

Ableton Live

Configure MIDI Preferences

1. Open Ableton Live
2. Go to Preferences > Link, Tempo & MIDI
3. In MIDI Ports, find “IAC Driver (Bus 1)”
4. Enable Track input (checkmark in Track column)
5. Optionally enable Remote for control messages

Create a MIDI Track

1. Create a new MIDI track (Cmd+Shift+T)
2. Set MIDI From to “IAC Driver (Bus 1)”
3. Set Monitor to In
4. Load an instrument (e.g., drag a synth from Browser > Instruments)

Test Connection

midi_connect("IAC Driver Bus 1");
let t = MidiTrack(1);
t << [C4 E4 G4 E4];
PLAY;

You should hear notes through Ableton’s instrument.

Recording

To record Resonon output:

1. Arm the MIDI track
2. Press record in Ableton
3. Run your Resonon code
4. Stop recording

MIDI clips will contain the captured notes.

Connecting Any DAW

These steps work with any DAW that accepts external MIDI input:

1. Open your DAW’s MIDI or Audio/MIDI preferences
2. Find the virtual MIDI port in the input list — IAC Driver on macOS, loopMIDI on Windows, or your ALSA/JACK port on Linux
3. Enable it as a MIDI input
4. Create an instrument track and load a synth or plugin
5. Set the track’s MIDI input to the virtual port (or “All Inputs”)
6. Enable input monitoring so you hear incoming MIDI in real time
7. Test with a basic Resonon snippet:

let t = MidiTrack(1);
t << [C4 E4 G4 E4];
PLAY;

To record Resonon output as MIDI clips, arm the track and press record before running your code.

Note

Some DAWs (like GarageBand) auto-detect virtual MIDI ports — no configuration needed beyond creating an instrument track.

Multi-Channel Setup

Use different MIDI channels for different instruments:

main.non

midi_connect("IAC Driver Bus 1");

let drums = MidiTrack(10);    // Channel 10 (GM drums)
let bass = MidiTrack(1);
let lead = MidiTrack(2);
let pad = MidiTrack(3);

In your DAW, create tracks listening to each channel.
