Riffpad

Build four sections, chain them into a song, and sketch in 12 scales — then route MIDI, host AUv3 instruments, or export MIDI and WAV.

Riffpad is a thumb-first MIDI piano roll for sketching melodies fast on iPhone and iPad. Draw notes on the grid, loop ideas, and run patterns standalone or as an AUv3 MIDI Processor inside compatible iOS music host apps.

Built for quick musical capture:

• Place, move, resize, copy, paste, and delete notes with touch-first gestures
• Load starter patterns for hooks, basslines, arps, and blank ideas
• Keep melodies in key with scale highlighting, snap, and quantize controls
• Loop short ideas, adjust tempo, and record simple live input
• Send MIDI to external gear, other apps, or AUv3 instruments
• Use the included AUv3 MIDI Processor in compatible host workflows
• Export MIDI files and audio previews through the iOS share sheet
• Import MIDI sketches when you want to keep developing an idea

Riffpad keeps your patterns local. There are no accounts, feeds, ads, tracking SDKs, or cloud sync.
