This app connects to the Mixer's RS232 port through an inexpensive RS232 Bluetooth Adaptor or a PC/RaspberryPI running a free small background program (VMXProxy - see http://goo.gl/iUfjW).
Bluetooth is simplest to set-up but has range limitations. WiFi has much better range and allows multiple users access.
Roland offer an iPad App to control the mixer, but this uses the USB port preventing USB recording, it also is 1:1 only allowing one user to alter the mixer settings. This app runs on Android (phones or tablets), allows multiple users to control feeds (e.g. Musician's controlling their own monitor mixes), and has a considerably simpler user interface.
VMX Serial Remote is not endorsed by Roland, and is not an official Roland product. It was written by a Sound Technician looking to solve a problem, and is provided free of charge. By use of a PC and the VMX Proxy script (freeware - available at the listed website) you can simulate a mixer so that you can evaluate the application, before you invest in any connection hardware.
