MIDI Sketch

A quick music making app MIDI Sketch is built for one thing: catching a musical idea before it disappears. Random Melody in your head? Chord progression you just found? A drum groove you're humming? Open the app, tap out the idea, and hear it back immediately — no menus to dig through, no setup required. Four focused editors, one tap away - Melody — a two-octave piano roll. Tap a cell, hear the note. - Chords — lay out a progression bar by bar, with instant playback of each voicing. - Riff / Tab — a 6-string tab grid with five tunings (Standard, Drop D, Open G, Open D, DADGAD) and a built-in chord library for quick reference. - Beat — a drum grid covering kick, snare, hi-hats, toms, crash, and ride. Built for speed, not composition. MIDI Sketch is a sketchpad, not a DAW. No mixer, no staff notation, no multi-track sessions — just the fastest possible path from idea to captured sketch. Max three taps to start entering notes. Everything you need to finish a thought: - Adjustable BPM with tap-tempo - Full undo/redo history - Attach a voice memo (up to 60 seconds) to any sketch — hum the part you can't quite notate yet - Add a quick text note alongside any sketch Your sketches stay on your device. No account required, no cloud sync forced on you — everything is saved locally the moment you make it, so you can capture an idea offline, on a train, in a rehearsal room, anywhere. When you're ready to share or back up an idea, unlock: - Email export — send a sketch (notation, chords, tab, or beat pattern, plus any voice memo) straight from the app - Microsoft OneNote sync — send sketches to your own OneNote account to keep alongside the rest of your notes The core toolkit — all four editors, voice memos, text notes, and up to 10 saved sketches — is free, no strings attached. The one-time unlock removes the sketch limit and adds export. Whether you're a songwriter, guitarist, producer, or just someone who gets musical ideas at inconvenient times, MIDI Sketch is there to catch them before they're gone.
