The kind folks at IK Multimedia have just sent me a new iRIG MIDI to try with Instrumental. It is a hardware MIDI interface that plugs directly into the dock connector.
To use it: plug it in, select the iRIG MIDI from Instrument’s destination list, and you’re away. Easy as that.
You can use the IRIG MIDI to connect to hardware synths, or even directly to a computer’s MIDI ports.
If you are using Instrumental in a performance situation, I would recommend using wired MIDI instead of Wi-FI, so that there is no chance of radio interference causing latency in the middle of your performance!
The iRIG MIDI includes a micro-USB port so you can keep your iPad powered while also using wired MIDI. This is not possible when you’re using the iPad Camera Connection Kit and a standard USB MIDI Adapter.
