Limitless sonic options, now for iPad

MixBox CS packs 70 award-winning mixing processors and creative effects into a convenient 500-series style iPad app.

Create, compare and save your own custom channel strips or multiFX chains, or choose from over 600 presets to give your creativity a kickstart. Whether in your favorite host app or stand-alone, MixBox CS combines a massive range of effects and powerful workflow to supercharge your mixes.

Every processor offers immaculate sound, from powerful digital effects to warm, authentic physical models of classic analog gear. Divided into Amps, Channel Strips, Delays, Distortions, Dynamics, EQ, Filters, Modulations, Reverbs and Saturations, it’s easy to find just what you need. Derived from IK’s award-winning T-RackS, AmpliTube and SampleTank products, they offer the same professional sound quality in a convenient, portable app.

All 70 processors can be inserted anywhere in the chain and are easily interchangeable. Each one comes with helpful controls and features for better mixing, production, and sound design.

MixBox is AUv3 compliant to work seamlessly with other music production and recording apps. It offers a freely configurable rack with slots for up to 8 processors, plus independent gain and mix controls, plus a sidechain control for dynamics processing.

Standalone, MixBox is perfect for live mixing, allowing you to set up to 8 separate racks, each with up to 8 processors. Combine and assign these to your audio device’s inputs/outputs, adjust each one’s gain and level, and you’ll have a massive digital FX rack with up to 64 simultaneous FX. It includes a selection of built-in audio demos to use as reference tracks to audition any of the modules and presets.

To get you going quickly, MixBox CS offers a comprehensive library of more than 600 presets covering everything from live mixing to sound design, for both individual processors and whole chains. You can also create and save your own presets for each individual module, the full rack, and even the whole app’s global state as a song.

With MixBox, you can enjoy supercharged mixes and FX, wherever you are.

Very Good

There are some nice effects here, and the ability to chain them together opens up a lot of possibilities, but there’s no overall dry/wet control, and no CC control or automation for the existing dry/wet control of individual modules. As such the app feels limited and incomplete. Hopefully they add those two things: automation and MIDI CC for dry/wet controls, and an overall dry/wet control also with automation and MIDI CC.

Once issue fixed, will change to 5 star

I am using musicbox cs in Garagband (latest version 2.3.10) as a plug-in. I can open it, add a rack or preset., but as soon as I start inputting sound (by using the virtual keyboard in GB), I hear a pop sound that then disables sound completely for GB (and any other tracks in the song, regardless if those tracks have musicbox or not as a plugin). I am using 2018 iPad Pro and to demo the musicbox app I simply used a grand piano instrument in the standard Keys patches of GB. I don’t think memory is the issue as I use memory intensive music apps frequently. The only way I can get GB to work again is to turn off the musicbox plug-in, exit GB fully (swiped app), go back in to GB, choose my song, and KEEP MusicBox off! Very disappointing as the app looks amazing and has powerful tools for mobile audio. Thank you for your attention.

Amazing app but needs a patch ASAP

I’m currently reinstalling this app which is a real game changer and incredible addition to my DAW. The problem is that it seems like when the app is applied to more than three tracks at a time it is overloaded and it stops running completely, shutting down and causing it to no longer open in any iOS DAW system. I’m running an iPad Pro with a large processor that usually can handle multiple apps running at once but this app causes everything to shut down. It may be too good to be true because the sound is amazing and I’m not willing to quit using until I can find a work around but other folks that are not tech savvy will get frustrated with this. A patch or update is needed ASAP to save this app otherwise.
