Make your first sound
Choose a preset and press the audition button, or play A, S and D on your computer keyboard. Hold a key for about a second when a preset has a slow attack.
Connect and shape
Connect a MIDI keyboard, use your computer or onscreen keys, or try the built-in examples. Drag a slider, enter a precise value or open the parameter help.
Stage mode offers large preset names, a setlist, MIDI CC Learn, pedal controls, master volume, expression and panic. Held notes and effect tails survive preset changes. Choose output device, channels and buffer size. Latency and stability depend on your Mac, audio device, driver and load; rehearse and verify your own setup before a performance.
Stage interface preview. External keyboards, audio interfaces, acoustic latency and long-session stage reliability still require hardware acceptance.
Record and subscribe
Record and export WAV / MIDI. Import standard MIDI 0/1 files for playback and looping, or play an audio backing track. Imported backing audio is excluded from WAV recording. This app does not process live guitar or microphone audio, and is not a DAW or AU/VST plug-in.
An auto-renewing monthly subscription enables playing, playback and recording. Eligible new subscribers receive a 3-day free trial. Prices and eligibility are shown in the App Store purchase sheet.
The trial starts after Apple confirms your subscription, not when you open the app. To avoid renewal, cancel in Apple’s subscription settings at least 24 hours before the trial or current period ends. Apple shows the effective timing. Local presets and recordings are retained after cancellation.
