POINTILLISME is a free, browser-based generative instrument built on integral serialism — the compositional technique developed at Darmstadt in the 1950s by Stockhausen, Boulez, and Berio, where not just pitch but every musical parameter (duration, dynamics, envelope, register, space, ornament) follows its own independent series.
Four oscillators run as a quartet. Each voice advances through seven independent series with coprime lengths, producing textures that never repeat. Ten ornament types — trill, mordent, glissando, tremolo, cluster, appoggiatura, acciaccatura, gruppetto, arpeggio — are serialized alongside the other parameters. The graphic score scrolls in real time, drawing each event as a coloured envelope shape in the style of Stockhausen's Studie II.
Hit record, then export:
— Audio (WAV or AIFF, up to 24-bit) for immediate use in any project.
— MIDI (Standard MIDI File, Type 1) with four separate tracks, one per voice. Drop it into your DAW and every voice lands on its own track, ready to be reassigned, edited, or used as a compositional skeleton for your own music.
The freeze function stops time and turns the score into a clickable instrument — tap any visible event to trigger it. Alternate between generative flow and manual triggering for live performance.
Included in the download you'll find HTML Instruments, a Max for Live device that lets you open POINTILLISME directly inside Ableton Live (requires Ableton 12 and Max 9). Alternatively, just double-click the HTML file to run it standalone in any browser and route your output to your audio interface, like any ordinary instrument.
Single file. No installation. No dependencies. Free.
