FAQ

Today PO-PatchStudio supports the PO-32 Tonic. Also sends drum sounds to the PO-35 Speak’s built-in Tonic channel.

Fuller support for the PO-33 K.O! and PO-35 Speak (their samples, speech sounds and backups) is on the roadmap. Their data transfer format isn’t solved yet, so the likely route is recording them over line-in. There is no promised date. If and when that lands, it will be described honestly here. Nothing above is a commitment to a timeline.

Yes. There is no licence, trial or paywall, and every feature is free.

From version 1.1 there’s an optional tip jar, in Settings or from the Support link at the foot of the sidebar. On iPhone and iPad you tip through the App Store. On desktop and the Android APK from this site, tips go through a web checkout: $5, $10, $20 or an amount of your own. A tip doesn’t unlock anything and the app never asks for one.

PO-PatchStudio builds on the community’s open-source reverse-engineering work and exists to give that work a friendly interface.

macOS, Windows and Linux as a desktop app, iPhone and iPad from the App Store and Android from Google Play or as a sideloadable APK. See Download and Install for the builds and system requirements.

The Studio keeps one working copy when you close the app, and each change overwrites it, so save anything you want to keep to the Library. The Library lives on your computer or phone. On desktop, WAVs, bounces and Microtonic exports save to your Downloads folder.

Close, but not identical. The app plays sounds with the open-source libpo32 synth so you can hear your work as you edit. Pattern playback and Bounce use each step’s morph and accents, as the PO-32 does. Anything you send plays through the PO-32’s own engine, so it sounds right on the hardware.

My Transfer to the PO-32 Didn’t Take. What Should I Check?

Section titled “My Transfer to the PO-32 Didn’t Take. What Should I Check?”
  • Put the PO-32 in receive mode (acc + sound) before you play the transfer.
  • Stop any music playing in other apps. The app stops its own pattern and previews for you.
  • Play the transfer loud and clean, close to the PO-32’s microphone.
  • Turn off effects, EQ and audio “enhancements” on your output.

Troubleshooting Transfers has the full list.

PO-PatchStudio recovers what it can and tells you what came back. If the recording breaks off part way, it keeps that take and asks you to play the backup once more, then reads the takes together to fill the gap. See Backup and Restore.

Only to record backups from the PO-32. Designing sounds and sending them to the device work without it.

Yes. PO-PatchStudio reads Sonic Charge Microtonic .mtdrum and .mtpreset files, in all three format generations, and can export a sound or kit back out. These are your own files; the app doesn’t include or share any Sonic Charge content. See Microtonic Import and Export.
