miRack is a Eurorack-style modular synthesizer, playground, and fx. It aims to provide user experience and audio quality close to those of the real Eurorack hardware.

The app comes with more than 500 modules created by third-party developers and adapted for mobile devices by miRack team. New modules are added regularly.

miRack supports both audio input and output, so it can be used to build both custom audio generators and effects, and can work with Audiobus and IAA hosts. Core MIDI support and MIDI learn feature allows to fully control the patch when miRack is running in the background.

Newer devices are recommended for better performance. Modules may vary greatly in CPU usage, the size of the patch your device is able run will depend on the modules used.

What’s New

Version 2.02

This update adds IAA MIDI support. This provides much better timing accuracy than Core MIDI when connecting other apps like sequencers to miRack (via an IAA host app).

Modular Playground on IOS!

MiRack is just a terrific modular experience on the IPad! For example, the Mutable Instruments clones sound fantastic and are simply a delight to mess around with. Modular synthesis can have a steep learning curve, but thanks to numerous VCV Rack tutorials on the internet you can get up to speed fairly quickly on how to make patches.

I hope this app continues to receive support as it really sounds and feels like your working with real modular gear in ways other apps just can not match. Moog Model 15 is outstanding but it is not even a quarter as flexible in routing and sound design as MiRack. The control voltage routing options alone are almost limitless. Honestly, MiRack could easily be used to teach a full year course on electronic music if one desired to do so. It is that authentic and true to real modular hardware.

Needs AU3 support, IAA or Audiobus like yesterday. Would love additional modules like Plateau (lush reverb) to be added. Even reasonably priced modules for purchase would be a fantastic way to always upgrade the app. As is, it is easily a 5 star app that can take you places only $10,000 worth of gear or more could take you previously. Kudos to the developers for bringing VCV Rack to IOS!

Fantastic, well executed and incredibly powerful... But I am concerned about viability

Just as we've seen with many other 'modular' environments - the initial release and subsequent couple months see a great deal of activity, updates and improvements. Then, after the initial hype/excitement wears off... Not much.
I'm a huge fan of VCVrack, and miRack has succeeded in porting this environment to iPad. However, in the process of doing so, seemed to burn a few critical bridges with the VCV community. Such circumstances gave me reason for concern, but the miRack developer seemed to mitigate the consequences and get a few other developers on board (via permission to release their modules). Unfortunately --- Since these initial updates... Very little in the way of new modules.

The lack of API, or apparent outreach/community-building efforts will be it's downfall. A lone developer can not be expected to maintain such an environment long-term. The fact that we haven't seen any new modules for 3 months is a big cause for concern. There are some MAJOR elements lacking(filters, sequencers) --- and without other developers participating in the creation/release of modules, its not likely that these needs will be addressed.

Fleece my knees & grease my bees

Sometimes you don’t realize what you are missing or that you’re missing anything at all until you go looking for the variable unknown. I’ve been involved in music making of all kinds for decades - from playing the drums, guitar, bass, and synths, in bands and in the studio to running live streams of mixes made on the fly in AUM to Mixlr that incorporate frequency filtering of found sound and reappropriating recorded political addresses with beats and effects - hammering the insanity we have in the top levels of government in the US ... but when I turned to this app I realized it was a supplement for my cptsd symptoms. It helps me relax when anxiety starts approaching the dangerous threshold. There’s something about loosely controlling the arbitrary nature of these devices, which if I had the cash I would surely be engaged in the real deal since the experience is just drastically different, but for a ten spot this is doing me just fine while giving me the knowledge of what I will need when I start buying individual modules for a real rack.
Thanks to the devs for this ✪✪✪✪✪
