bounceBuddy

A Logic stem bouncer that
actually works the way you work.

Reads your open Logic project, groups tracks the way you mix, and bounces every stem. Sends and sidechains included.

No templates, no setup, no tidy. macOS 14+ on Apple silicon.

Open your project. Hit Scan. Your stems appear.

No templates. No naming conventions. No routing prep. No minimum track count, and no "you need at least one aux channel" rule either. Whatever your session looks like is fine. bounceBuddy works directly from Logic's project data, not flakey screen-walking, so it adapts to every session automatically: summing stacks, folders, bus groups, Logic groups, multi-out instruments, Drum Machine Designer kits, stereo pairs. Already colour-code your tracks? Your colour scheme becomes your stem list.

Stems sorted. Versions? One click each.

Full mix, Instrumental, TV mix, a capella. Every version keeps its own stem selection, FX choices and bounce range: whole project, cycle, any section or any individual marker, with different markers per version. Arm them all and they bounce in sequence.

The hard stuff

It understands routing other tools pretend doesn't exist.

  1. Shared FX returns

    Reverbs, delays and parallel buses are detected automatically. They print into the stems that use them, or mute for dry passes. Mix level, dry, or wet + dry pairs.

  2. Every sidechain, alive

    Pumping compressors and multiband duckers like Trackspacer and Soothe keep working during isolated bounces. Every track keeps its own feeder, not one kick for the whole mix, feeding the detector without printing into your stem.

  3. Mix-bus control

    The full output chain, visualised, with per-insert bypass. Print without the limiter, keep the glue compressor. Everything is restored after the bounce.

  4. Nested sub-mixes

    Buses feeding buses feeding stacks. Grouping resolves to the level you choose. The nesting slider dials density live, from a handful of stems to fully flat.

  5. Online, offline and outboard

    Automatic. Offline for speedy in-the-box bounces, online in real time so a hybrid rig's hardware inserts and analog chains print into every stem. No re-patching.

  6. No project clean-up

    Muted, disabled, hidden, empty and no-output tracks exclude themselves. Solos cleared, click silenced. Every run, automatically.

Your outboard prints into every stem. No re-patching, no manual passes.

Hear it, and verify it, before you send it.

Bounced stems and versions render right in the app. Waveforms in every row, zoom, solo or mute any stem, or hear them all as a mix, without touching Logic. Then they're summed and phase-cancelled against your full mix: silence is the receipt. Every stem reports its length, size, peak and RMS. Proof, not hope.

Every bounce is saved as a snapshot. Flip between Live and Bounced, replay any pass, jump straight to its files. Changed a track since your last scan? Hit Rescan. Nothing to rebuild, no quitting Logic.

Watch it work

The whole thing, start to finish. Setup, scan, bounce.

Who made this

Built by a composer who got tired of losing Saturdays.

I'm Michael Edwards, a working composer and producer: film, TV, advertising, records. Close to 20 years in Logic, and the same job at the end of every mix: the client asks for stems, and two hours disappear into cleaning the session, grouping, soloing, muting limiters, dodging sidechains and hidden tracks, then starting again after one mistake. So I built the thing I wanted.
