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 - Also sends drum sounds to the PO-35 Speak's built-in Tonic channel 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.
