What's supported

• Note on / off — taps the currently selected track. Velocity is captured.
• Pitch bend — ±2 semitones default range. Affects 303 voices already playing, plus folds into the captured note (so live-tap retains sub-semitone bend).
• Channel filtering — listen to all channels by default; filter to a single channel in the MIDI tab if needed.
