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.

A classic algorithmic reverb effect based on the Freeverb algorithm by Jezar at Dreampoint. A Freeverb-style Schroeder/Moorer reverb based on the classic 8-comb + 4-allpass topology, with simplified controls and no stereo spread. This reverb creates lush, spacious ambience through a network of comb and allpass filters. Freeverb is widely used in electronic music production, ambient music, and sound design to add depth, space, and atmosphere to audio sources. The algorithm provides a smooth, musical reverb tail that works well on everything from vocals to synthesizers. This reverb only functions in mono and provides no stereo imaging, and the user can expect the same behavior as a classic Freeverb implementation otherwise.
