Turn a phone or tablet into a quarter-tone tuning surface and a pitch-bend Ribbon for six keyboard families — the notes a stock keyboard can’t reach, and a pitch surface for the ones that never had a wheel.
Born from the handmade AMG Scale — the same instrument that has toured stages since 2013, now living on the phone in your pocket.
Retune every note in quarter-tones — the notes between the notes that maqam lives in, and that a factory keyboard simply can’t play. Six families, each tuned its own way.
A pitch surface that replaces the wheel — and hands one to instruments that never had a ribbon at all. Slide for a sustained glissando, lift to snap back to the anchor, hold the pedal to keep it.
USB-OTG straight into the instrument. On Korg gear it auto-detects the model and picks the right family for you. Nothing to configure to get a note out.
Activate once and it runs with no network, no login, no subscription — on stage it never pauses to phone home. Your licence stays safely on your phone.
Classic wood, Modern slate, or Ivory light — the panel adapts to phone and tablet, and to your taste. Same engine underneath.
Slide along the Ribbon for a sustained glissando; lift to snap back to the anchor; hold the pedal to keep it going. Bend expressively where a stock keyboard simply can’t.
Tune each note by ear — a quarter-tone flat here, a whisper there — with six presets always a tap away. It’s the second reason this app exists.
If it speaks one of these tuning dialects, the app already knows how to talk to it.
