RollTab
AI piano autocomplete
Free · Designed for iPad. Not verified for macOS.
Play a phrase on your MIDI keyboard and hear an on-device AI continue it in real time. Human notes stay amber; RollTab’s response appears in violet.
RollTab turns your iPhone or iPad into an AI piano partner.
Connect a USB or Bluetooth MIDI keyboard, play a phrase, and pause. RollTab continues your performance in real time with a 125M-parameter music model running entirely on your device.
• Automatic mode answers after you pause
• Explicit mode lets you decide when to generate
• Live piano-roll view separates your notes from the AI’s continuation
• Adjust temperature, continuation length, timing, and pitch range
• Pause, continue, start a new session, and export the result as a MIDI file
• No account, cloud processing, or internet connection required
A MIDI keyboard is required for live input. You can also generate from silence in Explicit mode.
