Roland Juno 2 iPad controller with Arduino Ethernet demo
Demo of a custom device build around Arduino in order to control the Roland Alpha Juno 2 via Wifi.
The Arduino connects the Juno2 to the Wifi network of the iPad via an Airport router, an Arduino Ethernet shield and a midi shield.
I used Touch OSC to design the controller.
Touch OSC sends OSC messages (e.g /jun/DCO_Range 2.000) which are translated by the Arduino into Midi SysEx messages.
But the Arduino also translates Midi sysex messages from the Juno 2 into OSC messages (sort of loopback) so that when you change the patch on the Juno2, faders automatically move to the right position !
The code and detailled instructions will soon be published on http://4colors.free.fr
The control design mimics Roland PG300, but better !
