Music IO: MIDI over USB enables seamless MIDI communication between an iOS device and a Mac or PC using a standard USB sync cable. This setup eliminates the need for additional hardware such as camera connection kits, offering fast and reliable MIDI data transfer in both directions through a cable that users typically already own.

Setting up Music IO is straightforward: install the app on both the iOS device and desktop, launch them, and connect the devices with the USB sync cable. The software automatically detects the connection, allowing MIDI signals to be transmitted with extremely low latency, typically around a millisecond or less, ensuring smooth and responsive performance.

For users requiring audio transfer alongside MIDI, there is an expanded version called Music IO: Audio and MIDI over USB, which supports both types of data through the Mac server, simplifying installation and configuration. Additionally, dedicated VST and AU plug-ins facilitate the integration of iOS synthesizers and effects directly into desktop digital audio workstations, enhancing creative possibilities and workflow efficiency.
