Infinite ideas in seconds

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

Might be my favourite Output product yet... it’s like someone handed me a set of cheat codes.

Explore the details

Get into the far-reaching depths of PORTAL’s advanced features to dial in the exact sound you want.

Go beyond the presets and mess with grain controls, modulation, and FX.
Slow down and stretch your sounds. Sync them to your master tempo or leave unsynced for a more experimental vibe.
Add natural-sounding variations to envelopes for less repetitive, more organic sounds.
Alter the pitch of your sound without affecting its length or timing. Lock it into a scale for the most musical result.

Zero gravity

Easy on CPU — pair it with Output’s ARCADE or any other instrument to truly make sounds your own.

I’m hooked already. It is seriously good. It works great on vocals and makes cheap synths sound huge.
