The start screen

a quiet place
to begin.

Isai opens on a painting, not a wall of buttons. Pick a template, set the tempo and key, and press Return.

  • Five templates: beat, song, ballad, voice or empty
  • Recent songs, each with its own little cover
  • Recovers your song if Isai closed unexpectedly
The Isai start screen: a painted backdrop with the greeting 'good afternoon. what are we making?'

Isai is not a trial, a subscription or a cut-down "lite" edition.

It brings together the tools that usually cost hundreds: a playlist, a piano roll, instruments, a mixer, effects and mastering, in one free app that you own.

It is built to run on the computer you already have. A dual-core laptop with 4 GB of RAM is the target, and every heavy feature can be turned down.

Start with a template and press play, then go as deep as you like. Isai (இசை) means music in Tamil.
