SummonSound / 2026

SummonSound makes software for the space between the studio and the stage.

LEMMA is 001.

We build creative tools for musicians and visual performance — software for the moment a track stops being something you only hear.

LEMMA is the first of them. It takes video you already have and makes it react to the music you are playing. One idea, done properly, rather than an environment you have to learn before it does anything.

Software for sound that wants to be seen.

SummonSound

Music in. Image moves.

If you want to see what that means, the browser demo takes about thirty seconds. It mixes video only — the audio reaction lives in the desktop instrument.
