Built to be musical

Experience the playability of granular effects centered around the music you make. Granular sounds have been chaotic and abstract in the past, but PORTAL re-synthesizes sounds more closely related to the original input.

Time Stretch

Slow down and stretch your sounds. Sync them to your master tempo or leave them unsynced for a more experimental vibe.


Add natural-sounding variations to envelopes for less repetitive, more organic sounds.

Pitch Shift

Alter the pitch of your sound without affecting its length or timing. Lock it into a scale for the most musical result.
