This is the simplest musical CITO chain to try first.

Patch Shape

MIDI Capture -> MIDI Note -> Synth -> Device Out

You can replace Synth with Sampler, Wavetable Synth, Deep Beast, Halo, or Drift.

Steps

1. Place MIDI Capture from the CITO operators.
2. Place MIDI Note and connect MIDI Capture into it.
3. Place an instrument such as Synth.
4. Connect MIDI Note into the instrument.
5. Place Device Out.
6. Connect the instrument output into Device Out.

Expected Result

MIDI note input becomes note/control data, the instrument renders audio, and Device Out sends the result to the selected audio device.
