I don’t think this will ever be updated with new content from the current VCV/Cardinal universe, for those reasons alone. I still love it. Glad that it exists and all. But don’t buy it though with the hopes of new content added. ### 2/5 — Hard to use *2026-07-21, version 4.55* A little too fiddly for my use. Even on an iPad, the controls are too small and knobs too difficult to manipulate. While convenient in theory, I think VCV on a laptop is a lot better for learning and using modular in a virtual environment. ### 3/5 — 😐 *2026-04-11* 1. когда новые модули!? 2. просто добавьте кнопку: сохранить как —— 1. when are the new modules!? 2. just add a button: save as **Developer response:** Добрый день, можете, пожалуйста, написать на support@mifki.com в чем проблема с автосохранением и/или как бы вы хотели, чтобы это работало? Спасибо. ### 5/5 — The Controller Panel!! *2026-03-27, version 4.53* A MiRack lover for 3+ years, being on a break from due to no MiRack update, logging in 3 days ago, seeing the V4.50 update (!!!) I was happy! But then, the Controller Panel? In ~2 1/2 days, I’ve used it as the beginning panel for a new: - double 4 Step binary pitch sequencer! - individual clock for each of the 8 steps! FWD/REV control for each - 2 to 8 steps for each Step’s pitch - 4 binary pitch buttons = 16 diff. Pitches for each step. - quad quantizer More coming 8n the future, depending on Panel upgrades. Will be freely available. (Is now, early as is, at Reddit.) WtG MiRack ciders!!!, Ryk 🇨🇦 ### 3/5 — The promise Updates *2026-02-04, version 4.06* I remember, the promise, of many updates soon. But nothing at all... ### 5/5 — Insane! *2025-12-28, version 4.06* This app along Koala Sampler are the 2 best music apps on the App Store ### 5/5 — AUv3 is great - VST and ASIO? *2025-11-07, version 4.06* Now that VST and ASIO are open source, it would be an amazing new addition. AUv3 support with the in-app purchase has unlocked such great utility. ### 5/5 — Money saver *2025-08-26, version 4.06* I was considering getting into modular sythesis, then I found this, which showed me how expensive and futile the hobby would be for me. Definitely do this before spending money on that empty Eurorack case. ### 5/5 — Modeler *2025-02-16, version 4.05* Seq ### 5/5 — Amazing *2025-02-14, version 4.05* Great app. Perfect for sound design on the go ## Frequently asked questions about miRack ### What is miRack? miRack is a polyphonic Eurorack-style modular synthesizer and effects environment.

All modules placed on that row will be present on screen in Controller mode. * Improved color selection for Controller label background/foreground colors. * Rack position and zoom is now correctly saved and restored when entering and exiting Controller mode. APP FEATURES * Imroved handling of external assets, e.g. samples loaded to sampler modules. We fixed a couple of bugs in this area and made it easier to share patches that use external assets. Please read the updated External Assets section in the app manual for details. ### 4.54 — 2026-04-03 CONTROLLER * It is now possible to place additional modules next to Controller module on its row.

When a patch containing Controller module is loaded in miRack AUv3 plugin, the designed panel will be shown, hiding the rest of the patch. Now you can create effect or instrument patches having all the power of miRack modules under the hood but hiding their complexity behind a custom UI. Controller module is available for purchase in the module browser. See the manual for more details about its functionality or try the included Controller Demo patch. AND ALSO * Improved support for the latest iOS, iPadOS and macOS versions and major DAWs. * Improved support for mouse within miRack, both on iPadOS and on macOS. * Improved support for Apple Pencil. Double tap and squeeze actions can be configured in application settings. * Custom names can now be assigned to AUv3 parameters mapped to module controls. These names will be visible in DAWs instead of the default 'Parameter NN' names. Note that not all DAWs and AUv3 hosts support dynamically changing parameter names, some may even not work correctly with them, therefore this feature needs to be enabled in miRack settings first. * AUv3 hosting modules now support built-in Apple effect audio units. They are hidden by default and can be enabled in the module menu. ### 4.52 — 2026-03-22 INTRODUCING THE CONTROLLER MODULE Controller module allows you to design a custom "front panel" UI for a patch.
