Hum It.
No keyboard? Hum the tune. Sing, hum or beatbox into your mic, watch it land as notes, and take the MIDI into any music app. All of it happens on this device.
Sound starts when you tap. Headphones help: then the playback cannot leak into the next take.

HOW IT HEARS YOU
Every 10 milliseconds the page measures how loud you are and finds the pitch with a method called YIN, which looks for the length of the repeating wave in your voice. A run of steady pitch is a note; a jump, a gap or a fresh push of breath starts the next. The note's pitch is the middle of what you sang, so sliding in or a wobble does not move it. That is arithmetic, not AI: no model is downloaded and nothing you sing is sent anywhere.
BEATBOX
Each hit is sorted by where its sound sits: mostly low is a kick, mostly a hiss is a hat, anything in between a snare. Voices differ, so the sort can be wrong; tap a hit on the roll to change it. In the MIDI file the hits are General MIDI drums on channel 10: kick 36, snare 38, closed hat 42, which every drum machine and DAW reads.
THE FILES
DOWNLOAD MIDI saves a standard MIDI file with your tempo and the sound you picked as its instrument; drop it on a track in Ableton, FL Studio, Logic, GarageBand, BandLab or anything else and play it with whatever you like. DOWNLOAD WAV saves exactly what PLAY plays. The page remembers your mode, sound and tempo in this browser, and nothing else; the recording is gone when you close the page.
WHAT IT IS NOT
It listens to a take and then turns it into notes; it is not a live controller that plays a synth while you sing, and it reads one note at a time, not chords. For live voice control there are paid apps made for that; this is the free way to get a tune out of your head and into a file.
Make a beat under it in Broke DJ, or turn a sound into pads in The Sample Maker.
