FINALLY you can use your AUV3 instruments and effects in a tracker. That isn’t the only thing that sets it apart from other trackers. It has a true touch menu focus, where you can interact with directly with the screen elements, and not just to a means to move a cursor around, like on the M8. The app really highlights the positives of using a tracker, where the ease of navigating around the songs, chains, and phrases shows off just how fast the tracker workflow can be. I’ve always been frustrated with drawing in notes on a piano roll, particularly on the iPad, where a note block can be easy to bump by accident. There is a workflow to learn, but it doesn’t have to feel like programming, as here you can play in notes right to the phrase. It just makes so much more sense to represent notes this way, where they can be seen all at once, and not spread across multiple different piano rolls. But even if you like getting MIDI put together in that format, you can still do that, and bring in your MIDI into the project. Just a fantastic app, and one that can be the centerpiece of your work. ### 5/5 — Best Audio Tracker on the App Store *2026-09-15* This app beats the M8 for three reasons: polyphony, Auv3 support and 12 tracks. Not to mention price!!! It also has a unique selection ring input method that provides fast workflow. If it adds game controller support it will be unstoppable! It is worth the price just for the crazy voice synth!!! **Developer response:** Thank you for the kind words! Game controller support is on the TODO list, you can expect it soon! ### 5/5 — iOS Tracker? Yes, please. *2026-09-15* This is the best tracker for iPad I’ve found. I have a Dirtywave M8 (hardware) and Renoise (Mac). The M8 app on iPad is lacking in features. WBTRK hits the sweet spot. Love it! Note to developer: please add arrow key keyboard input for changing notes in record/edit mode for ease of quick changes. Also, please add Braids and Plaits engines. I respect the work you put into the current engine, but I do love Mutable when I can get it ;p) **Developer response:** Thank you! Game controller support is coming, so at the same time it will be an easy add to enable it for the arrow keys as well. For now you can use your keyboard as piano keys for fast input, similar as in Renoise. I hear you with Mutable Instruments! I have done a quick check and it's definitely possible, so it's going on my TODO list as well. ### 5/5 — Amazing Tool! *2026-07-29* Wow, what an amazing tool, almost like the M8! So cool! Would be super awesome if it could not only host AUv3 Instruments, but AUv3 FX as well. Especially since Eventide FX/FabFilter Plugins are a thing on mobile these days! **Developer response:** Thank you for the great feedback! I will look into the Auv3 FX, hopefully it can come to the app in the next release! ### 5/5 — Brilliant *2026-07-26* Trackers Forever. Extraordinarily well thought out, moves the trad workflow into a fluid touch app future. Radial menus, AUv3, sample chopping etc etc. Top of the platform. **Developer response:** Thank you for the kind words, happy that you like it! ## Frequently asked questions about WBTRK ### What devices does WBTRK support?
