Export All Tracks gives you one file per track, without the bus and send processing that track goes through in your mix. Stems are groups: the drums as one file, with their bus compression, reverb sends and sidechains printed the way you hear them. bounceBuddy works those groups out from your session, bounces each one, and null-tests the set against your full mix.
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.
Not your arrangement, no. All the analysis runs against a duplicate of your project data rather than the session itself, and bounceBuddy 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.
Yes. Six nesting buttons take the list from most grouped (every stack and bus is one stem) to fully flat (every track is its own stem), and the project remembers the level you pick. Select any tracks and click Create Group to bounce them as one combined stem. Right-click a track to promote it out of its group or rename it, or click the trash on a group to split it into separate stems.
At mix level, each stem is printed with its reverbs and delays baked in. Switch Wet/Dry to Wet + Dry and every stem comes out as two files: DRY, the stem with its send effects muted, and WET, only what that stem sends to your reverbs and delays. Play both together and you get the stem exactly as it sits in your mix, so whoever mixes next can rebalance or swap the effects. Dry Only gives you just the dry files.
Yes. Press + to add a version, such as an instrumental, a TV mix or an a capella. Each version keeps its own stem selection and its own range: the whole project, the cycle, or any section or marker from your arrangement. So “chorus 2, no vocals” is just a version with its range set to that marker. Arm the versions you want and they bounce one after another, each into its own set of files.
After the bounce it sums your stems, flips the polarity and plays them against a full-mix render. If the stems really add up to your mix, the two cancel to near silence. Every bounce gets a verdict: Verified when it cancels, or an amber flag telling you to have a listen when something doesn't add up. You can switch it on or off in Settings.
Every build is checked against real sessions from my own work, with stem lists I've signed off by hand. If a single stem comes out different, that build doesn't ship.
Yes. It's a one-off purchase with no subscription and no activation to expire, so the version you buy keeps running on the Logic you've got.
Both. Offline is fastest; choose online (real-time) when your session uses outboard hardware. Inserts, analog chains and summing print into every stem.
Yes. bounceBuddy 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. bounceBuddy'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.
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.
Stems that keep your mix-bus glue. Normal stems are bounced with the bus compressor and similar mix-bus processing switched off, so they can be remixed cleanly, but played back together they lose that glue. In-Context stems are bounced with the processing on and driven by the whole mix, so together they sound like your finished mix, and the report after each bounce tells you how closely they add up. It's off by default. Switch it on in Settings and you get an extra folder next to your normal stems.
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.
Keep Logic on the same screen, and don't lock the Mac, while it bounces. If Logic is on a second display, behind a full-screen app or the screen locks, bounceBuddy can't reach it. It stops that stem and tells you, rather than guess. Bring Logic back to the main screen and run it again.
Accessibility permission. The bounce drives Logic for you, so macOS asks once for Accessibility access. If a bounce never starts, check System Settings, Privacy & Security, Accessibility.
Local Network prompt. On macOS 15 and later you're asked once to allow local network access. bounceBuddy uses it only to talk to Logic Pro on your Mac. Please allow it.
Where do I enter my licence key? In bounceBuddy, Settings, License. Paste the key and press Activate. It works on two Macs; Deactivate frees one.
