About this app

PO-PatchStudio designs drum sounds, kits and patterns for Teenage Engineering's PO-32 Tonic, then sends them to your Pocket Operator over sound. Free, with no ads and no account.

The PO-32 has no USB data connection. It loads new sounds the way an old modem does, by listening through its microphone. So this app does the fiddly part on a proper screen: build a kit, hold your phone next to the PO-32 and press play.

WHAT YOU CAN DO
- Shape all 16 sounds with the full set of 21 synth parameters, plus both ends of the morph
- Program 16-step patterns on the pads, with accents, and hear them before you send
- Send a whole kit, a single sound or a pattern to the PO-32 over audio
- Back up your PO-32: record its data dump through the microphone and the app decodes it into a kit you can edit
- Import Microtonic .mtdrum and .mtpreset patches, including files from older versions of Microtonic, and export your sounds back out
- Keep kits, sounds and patterns in a local library with tags and favourites

WORKS WITH
- PO-32 Tonic

HOW TRANSFER WORKS
Put the PO-32 in receive mode (press acc + sound), turn your phone's volume up and play the transfer into the PO-32's mic. To back up, start recording in the app, then hold write and press sound on the PO-32.

Previews come from an open-source recreation of the PO-32's synth, so they sound close to the hardware but not identical. Once a sound is on the PO-32, it plays through the device's own engine.

A NOTE FROM ME
I'm a solo developer and a PO-32 owner. PO-PatchStudio stands on the open-source libpo32 library by Eric Lewis and years of reverse-engineering by the Pocket Operator community, which is why it's free. If something is missing or broken, tell me.

What’s new

A new phone layout with four Studio tabs, plus Support, More Apps and a tip jar in the menu.
Sounds you send to your PO-32 now play at the morph you hear in the app.
Loop Preview repeats the sound you're editing on every beat, and Restore Demo Kit brings back the House Kit.
If a backup recording breaks off, play it once more and the app fills the gap, plus smaller fixes.
