The PUC is a wireless MIDI interface designed specifically for iOS devices. PUC Connect is the app designed to establish your iPad/iPhone connection to the PUC hardware. PUC Connect also monitors your PUC hardware for battery status, firmware updates, and connection protocol selection. If you have a MIDI keyboard controller, home digital piano, synthesizer, or computer controller, connect it to the PUC and play your musical instrument apps from your favorite MIDI controllers. The PUC allows you to wirelessly connect an iPad, iPhone or Mac to a variety of MIDI compatible devices such as a keyboard, DJ controller, drum pad, floor pedal controller, and more. The PUC can also work with other platforms that support MIDI connections over Bluetooth wireless. The PUC communicates directly to the iPad, iPhone, or Mac via Bluetooth Smart (Low-Energy 4.0) You have an iPad loaded with amazing synthesizer & music creation apps, but connecting your controller creates a tangled mess and no longer makes you mobile. The PUC and the PUC Connect app makes MIDI connectivity easy so you can get on with your business – making music. PUC also connects to your Mac for wireless CoreMIDI control.
