Core Technology

Ultra-Low Latency

Receives real-time Note On/Off MIDI signals with less than 10ms latency, ensuring your chord display is as instantaneous as your playing.

Chord Retention

When you release your hands, the chord remains on the screen for 5 seconds so you or your bandmates can still see the last played chord.

Stage Mode

With one click, the sidebar panels collapse, expanding the chord monitor to full screen for distraction-free, high-visibility legible from several feet away.

Wheel Telemetry

Fully replicates physical pitch bend and modulation wheel movements directly on the screen in real-time.

Visual Precision

Dual Monitor Cards

CHORD MONITOR: Simulates a glowing hardware LCD screen displaying the exact chord. The text dynamically scales down for complex chords (e.g. Ealt(b9)/C) so they never clip or wrap.

ACTIVE VOICING: Displays the active notes stack with a clear underline highlighting the root note of the chord.

61-Key Responsive Keyboard

Renders a highly responsive vector keybed (C2 to C7) showing real-time physical key presses for visual feedback.

  • Keyboard Split Marker: Visually displays where your keyboard split point is configured, matching Yamaha arranger style splits.
  • Scale Guide Highlighting: Center cyan pulse dots glow on the keys that belong to a selected scale (e.g., C Blues or G Dorian), helping you practice runs and stay in key.
