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

The app comes with a growing collection of open-source modules that are being created by third-party developers for and adapted for mobile devices by miRack team.

miRack can work with Audiobus and IAA hosts, supports Core MIDI input and simple background audio mode.

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 1.50

* Audiobus and IAA support. This makes it possible to post-process, mix and record miRack output in Audiobus, AUM and other compatible host apps. See http://audiob.us

* Holonic Systems: Holonic Source module connects to Holon.ist app and converts various real world data to CV. This includes device sensors, weather, motion and health data, location, and data from Apple Watch and several other devices. It is a completely new way to control your music, e.g. try syncing BPM to your heart rate! Holonic Systems module pack also includes several other useful modules. See http://holon.ist

* miRack is now present on Patchstorage - a website for sharing patches and presets for audio/video software and hardware. Please note that currently it's required to manually zip miRack patch before upload (and unzip after download). This can be easily done from Files app. Patchstorage also requires an image to be uploaded for each patch, this can just be a screenshot of miRack with the patch.

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!

Better and Better with each Update

With the latest introduction of Plateau Reverb I’m pretty happy. I wonder how far this port will be developed, which thus far seems to be moving along quite quickly! I’m seriously impressed with the speed at which the developer responds to requests and gets things implemented, with IAA it becomes possible to now process things using external plugins for some final polish. I’ve also tested out sending MIDI from Patterning 2 and that works great. I’m excited to see where this ends up, its an extremely fun app.

Nice port of vcv rack could use some info tho

Port works great, touch interaction seems to work well.
Everything is running smooth on iPad air2 which is pretty old now so that’s great. I would love to see some info in the app such as cpu load, audio info such as sample rate , buffer and latency info, and audio interface options. I’ve yet to try it with my es8 for interacting with my modular yet...
I REALLY hope this app will continue to be supported.
I’ll be following it closely. Fluxwithit
