Two apps for KaraokeVersion users. Different design goals, different platforms, very different levels of active development. Here's the honest comparison — what each one does well, where each one falls short, and which workflow fits yours.
If you're a KaraokeVersion user on a Mac who needs to browse, download, organize, and practice a large track library, BTM is the clear choice — it's free, built specifically for KV's catalog, and actively updated (v3.2 shipped March 2026).
If you need a live-performance player on an iPad or iPhone with multi-channel routing to stage audio hardware (Midas M32, Behringer X32, Cymatic uTrack24, Focusrite Scarlett), Muzoma still has a place in that niche — with the caveat that it has been effectively dormant for around five years, and the developer publicly recommends considering alternatives.
Most gigging musicians end up using both: BTM on the laptop for library management, a dedicated player on iPad for the stage.
Free Mac app for KaraokeVersion users. Built by a gigging guitarist who was drowning in 300+ unorganized stems.
Multi-channel playback and per-song editor. Originally iPad-first with Mac/Windows as secondary playback targets.
| Feature | BTM | Muzoma | Notes |
|---|---|---|---|
| Active development | Yes — v3.2 shipped March 2026 | Dormant ~5 years | Muzoma developer explicitly recommends considering alternatives. |
| KaraokeVersion library sync | Full purchase-history import | Per-song download via "Online Content" | BTM pulls your entire KV purchase history into a single browsable view. |
| 93K+ song catalog browser | Full search, previews, artist browse | No in-app catalog | BTM gives you KV's full catalog inside the app with 30-second previews. |
| One-click stem downloads | 4 parallel connections | Per-song download | BTM's parallel downloads are tuned for KV's rate limits. |
| Key shifting before download | ±6 semitones | No pre-download shift | Native to BTM's download workflow. |
| Auto lyrics fetch | Genius API | Manual in Producer editor | BTM grabs lyrics automatically; Muzoma requires hand-editing. |
| Auto chord fetch | Cifra Club + Ultimate Guitar | Manual chord editing | Same story — BTM automates what Muzoma asks you to type. |
| MIDI chord generation | Exports to DAW | No | Useful if you want chord tracks in Logic / Ableton. |
| Wishlist + price-drop alerts | Yes, with notes | No | BTM watches KV pricing and notifies you. |
| Song update notifications (KV re-records) | Automatic | No | KV occasionally re-records tracks; BTM tells you. |
| Web Audio mixer (solo / mute / pan) | In-app mixer | Multi-channel playback | Both mix, different scopes: BTM for practice; Muzoma for multi-output live routing. |
| Multi-output audio to stage hardware | Not designed for live routing | Midas / Behringer / Cymatic / Focusrite | Muzoma's strongest feature. BTM is a practice/library tool, not a live router. |
| Band sync / peer-to-peer | No | Muzoma band-share + Airplay | Muzoma can sync across devices for a live band. |
| Multi-folder library scan + "Fix & Organize" | Batch tool included | No | BTM cleans up years of messy download folders. |
| WAV conversion | 24-bit, 44.1 / 48 / 96 kHz | No | Useful for DAW-quality rendering. |
| Mac (Apple Silicon) | Universal — fully supported | macOS 11+, M1+ required, secondary target | BTM is Mac-first. Muzoma's Mac build is a side target. |
| Intel Mac | Supported (v3.2+) | Apple Silicon required | BTM v3.2 added native Intel Mac support. |
| iPad / iPhone | No | Primary platform | Muzoma is strongest on iOS. |
| Windows | Planned | No | BTM Windows support is on the roadmap. Muzoma's desktop story is Mac-only. |
| Price | Free forever | Free (open source) | Both are free. BTM monetizes via KV affiliate; Muzoma relies on community. |
| KaraokeVersion account required | Yes (free or paid) | Yes | Both tools assume you already use KV. |
Best of both worlds: run BTM on your Mac to manage, download, and prep your library, then load the final stems onto your iPad for live playback in Muzoma (or Stage Traxx, or audioCue). The two tools don't overlap much — they compose nicely.
Muzoma became open source at version 3.0.0 and the main app has been dormant for roughly five years. The developer explicitly recommends considering alternatives, noting there is no guarantee of long-term availability.
Yes. No account, no subscription, no ads. When you buy KV tracks through the app, it uses a KaraokeVersion affiliate link automatically — that's what funds development at no extra cost to you.
Muzoma — its multi-channel audio output to hardware and iPad portability are purpose-built for stage use. BTM is optimized for library management, stem downloads, key shifting, and practice — not live multi-output routing.
BTM, clearly. It imports your entire KV purchase history, runs a multi-folder Fix & Organize batch tool, supports wishlists with price-drop alerts, sends update notifications when KV re-records a track you own, and auto-fetches lyrics and chords. Muzoma handles per-song playback and editing but doesn't manage a library at this scale.
No — and most gigging musicians don't. BTM on a Mac for library management, a dedicated live player on iPad for the stage. The two tools solve different problems.
Not yet. BTM is currently Mac-only (Apple Silicon fully supported, Intel Mac support added in v3.2). Windows support is planned for a future release — follow the BTM page for updates.
Universal build — Apple Silicon and Intel. No account required, no subscription, no ads. Built by a gigging guitarist for gigging musicians.
