The pocket FM groovebox
A four-operator FM synth and a four-track step sequencer for iPhone and iPad, drawn like a handheld game cartridge. Sixty-two sounds to start from, and a song already playing when you open it.

Every sound in this video is PIKOTO playing its demo song.
Pick a page and the eight encoders edit it. The screen always shows what you're turning: a scope of the track and a diagram of the page.
Each voice is four operators with six waveforms, stepped ratios from 0.25 to 32, fine tune, level and an envelope each. The diagram shows which operators you hear and which ones bend them.
A multimode filter with its own envelope, then modulation on every track: two LFOs and SLOPE, a modulator that runs as a looping ramp or an envelope. Route each one to pitch or to any of 64 sound parameters.
Four tracks of up to 64 steps, each with its own length and speed. Hold a step and every knob locks a value to it. Record live, and chain sixteen patterns into a song.
Flip the sixteen pads into a keyboard, or into the notes of any of fifteen scales in any key, so every pad is a right note. Touch near the top of a pad to play softer.
Hold a pad to bend the music, let go to snap back. Hold several at once. Play them on the whole mix or on one track, and record them into the pattern.
A short guided tour on first launch shows you the machine. After that, the manual is one tap away in the ≡ menu, and the bottom line of the screen tells you what you're touching.
Four tones and a hand-drawn 5x7 font, everything on a pixel grid. Pick a palette in the app. Pick one here and this page follows.
The free app is the whole instrument. One purchase, yours to keep, adds the rest. No subscription, no ads, no timer.
