Want to lay down some tracks but all you've got is your iOS device and a Mac? With an OpenSound Control (OSC) app on your iPhone and server on your Mac you can record a virtual keyboard over Wi-Fi.
This is a pretty simple hack, and as MacLife explains, it's especially helpful if you hate using an on-screen keyboard on your computer and don't want to pay for or transport a hardware keyboard. Here's what you'll need:
- An OSC app for iOS like TouchOSC (attractive and comparatively cheap!), XENON Groove Synthesizer (synthy!), Pianist Pro (nice!), ThumbJam (a little cheaper!), or Hex OSC (unusual and expensive!)
- An OSC server that's compatible with your app of choice (generally either Pure Data or OSCulator)
- A computer with Garageband (or your MIDI sequencer of choice)
- An iOS device
All you need to do is launch the server on your computer and set it as a MIDI input in Garageband. Then launch your OSC app on your iPhone, get it synced up with the OSC server on your computer, and start playing.
