musicIO :: Audio and MIDI over USB between your iOS device and your Desktop DAW. The app is designed for the Mac, but also works with most Windows DAWs. One easy-to-use, professional app.

Easily send audio from your iOS device to your desktop DAW using USB; musicIO lets you integrate Inter-App Audio compatible iOS synthesizers with a traditional desktop DAW system. MIDI is built in to musicIO too; everything you need, all in once place. It's simple, reliable, and near-zero latency.

musicIO is a joint effort by three of the most respected iOS music app development teams. Confusion Studios makes MIDI Designer Pro, the most innovative MIDI controller platform for iOS. MIDI Designer is adored by users, loved by Music Industry press, and trusted on stages and in studios around the World. Audeonic Apps makes the pioneering MidiBridge app, an essential tool for routing and filtering MIDI messages on iOS; they also provide the MidiBus software library, which powers dozens of successful music apps (including musicIO). The Secret Base Design team has built a range of pioneering apps providing high-speed MIDI and audio connections over Bluetooth LE and WiFi, as well as unique signal processing apps.

The three teams have joined forces to build the only fully integrated USB audio and MIDI solution that doesn't require additional hardware. It's been in development for months, from developers with decades of experience. musicIO lets your iOS device become an integral part of a modern professional music production system.

• Low latency audio from iOS to your desktop DAW, with crystal-clear 32-bit resolution. Native support for IAA allows for the best possible audio quality, and seamless integration with iOS synthesizers and effects apps
• Send & Receive MIDI between any CoreMIDI apps over USB (Lightning or 30 pin) with no perceptible latency nor jitter
• Large sysex messages (eg. bulk dumps) handled seamlessly
• Choose "send to" ports (OSX and iOS)
• Choose "receive from" (OSX): route MIDI from anywhere to your iOS device
• BridgeClock, a ground-breaking inter-device MIDI-clock-synchronization technology, provides jitter-free sync between platforms

• musicIO is designed to work with iOS 7 or newer, OS X 10.7 or newer, and Windows Vista, 7, and 8. Audio is transferred in 32-bit stereo. The PC client currently handles a 44.1khz sample rate, while the Mac can handle all sample rates. Please check VST compatibility if you are using a PC DAW.

Was so excited to use this...

I got this app to replace my hardware connection to my iPad (Iconnect MIDI). I got everything installed (Mac) properly, but everytime I send MIDI notes from my DAW (Ableton 9), the server app crashes. EVERY. SINGLE. TIME.

I have put in two emails to tech support over the last 2 months only to be completely ignored. I understand that they might be understaffed, but at least some kind of acknowledgement would be nice.

Hoping they get their act together. Such a bummer that I can't use this after I bought it.

*used to be an* Essential App


*How unfortunate. I see that I wrote a shining review years ago when I had my iPhone 5s. My 6s presented problems that I thought my Xs would fix. Not true.
I have tried contacting this company over the years in every way possible even sending messages to their partner companies in hopes to inspire some communication. I am giving my paid version up as a lost cause. RIP MusicIO.

Original- -
This app IS the way the wind is blowing. Other leading VSTi app assemblers require other cables and connectors and offer no other possibilities. The connection to OS X is simple and inserting into my DAW is very easy and follows standard procedures. I can actually put different VSTi's into different channels and control each with outboard controllers. If I want to leave the peripherals at home it works independently and still sends audio through the phones jack.

Having said all that, I only gave 4 stars because the user layout could use some evolution. There are just a couple simple things to change. There are also some crashes that happen. Through rebooting (sometimes a few times) it will repair itself. Order that apps are launched is important.
I very much believe in this company and its evolution.

Works wonderfully!

This is an ideal way to connect the iPad to Logic (and presumably elsewhere, Logic's all I've tried so far; it's so sweet I can't drag myself away to experiment!), both for MIDI and audio from iPad apps (and back out, too). I had a little trouble at first getting audio recording to work, but got a swift reply from the developers that sorted everything out—Logic IS weird as we all know, but great once you know the workarounds. For me, MusicIO is an essential tool, the thing that finally makes ios music stuff real.
