← Back to REACTOR App User Guide
The REACTOR app includes a built-in chromatic tuner that detects pitch through your amplifier's hardware — no microphone needed. It requires a connected REACTOR.
Note: The tuner uses a fixed reference pitch of A = 440 Hz. This cannot be changed.
Accessing the Tuner
Tap the gear icon → Tuner in the Settings menu.
Reading the Tuner
- The large note letter in the center shows which note the tuner detects (e.g., E, A, D, G, B, F#). It turns green when you are in tune.
- The scale indicator below spans -50 to +50 cents. Left of center = flat, right of center = sharp. Adjust until the center marker turns green.
