Editorial interest 86/100 Selection signal · not a rating of the site

Flow uses a phone as a USB-MIDI or WiFi controller, with pads, faders, XY surfaces, and portable file-based layouts.

Landing page captured for the 2026-08-24 issue.

Field notes

The browser version sends MIDI over WiFi through a free desktop bridge or a VST3 plugin, while the planned native version is intended to work over USB as a class-compliant MIDI device. Its central unit is the Flowpack: a local file containing the surface layout, MIDI mappings, theme, and optional samples. The page reports approximately 20 ms offline cold boot time and zero message loss in a sustained soak test.
