A Mac with Apple silicon running macOS 14 or later, Logic Pro 12 or newer recommended (Logic Pro 11 works too), and your project open in Logic. Logic can run in any language it ships — English, German, French, Spanish, Italian, Portuguese, Japanese, Korean or Chinese — and your Mac can be in any region. First launch runs a short setup wizard: pick your stems folder, confirm the bounce format, and import your Logic key commands.
Yes. Bounce Buddy reads Logic's on-screen labels in whichever language Logic is running — German, French, Spanish, Italian, Portuguese, Japanese, Korean and Chinese (Simplified or Traditional) all work, alongside English. Bounce Buddy's own interface is in English for now.
Where you are doesn't come into it — only the language Logic is running in. English (UK), English (Australia), English (India) and every other region are fine. So is a language Logic doesn't ship at all, like Dutch, Swedish, Polish or Danish, because Logic runs in English for those anyway. You can also set Logic on its own to English in System Settings → General → Language & Region → Applications, and leave the rest of your Mac as it is.
Scanning reads your project's saved data directly — no UI involved. The bounce itself drives Logic for you (soloing, bouncing, naming files), and macOS requires Accessibility permission for that. Grant it once in System Settings → Privacy & Security → Accessibility.
Not your arrangement, no. All the analysis runs against a duplicate of your project data rather than the session itself, and Bounce Buddy never writes to your project — nothing is added, deleted, moved, renamed or re-routed. It does ask Logic to save before it scans, so the read is of what's actually in front of you rather than the last time you pressed Command-S. During a bounce it drives mutes, solos and mix-bus plugins, and restores every one of them when it's done.
Every build is re-run against a library of more than sixty saved project states from my own work — nested stacks, Drum Machine Designer kits, multi-output instruments, sidechains, the messy ones — plus 121 constructed test cases for the awkward routing shapes. The stem list it produces is compared against the list I've checked by hand and signed off. If one stem moves, changes name or changes parent, the build fails and doesn't ship.
Both. Offline is fastest; choose online (real-time) when your session uses outboard hardware — inserts, analog chains and summing print into every stem.
Yes — offline mode opens any previous bounce or saved project state, so you can review stems, play them back and share them with Logic closed.
Into the stems folder you chose in setup, named from your template. The folder icon in the app's toolbar reveals the full path; snapshots jump straight to any past bounce's files.
Fair question. If I ever stop working on Bounce Buddy, for any reason, the last build goes out without a licence check and stays downloadable. Nothing phones home and there's no activation to expire, so what you've bought keeps running on the Logic you've got. Day to day I use it on my own work every week and test it against each Logic update, but you shouldn't have to take that on trust.
