VMX Serial Remote for V-Mixer

An application to control a Roland V-Mixer Mixing Desk (M-300, M-400 and M-480).

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 - https://github.com/JamesCC/VMXProxyPy).

Bluetooth is simplest to set-up but has range limitations. WiFi has much better range and allows multiple users access.

Roland offers an iPad App to control the mixer, but it uses the USB port, which prevents USB recording, and it is also 1:1, allowing only one user to alter the mixer settings. This app runs on Android (phones or tablets), allowing multiple users to control feeds (e.g., Musicians controlling their own monitor mixes), and features a considerably more straightforward 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. Using a PC and the VMX Proxy script (freeware, available at the listed website), you can simulate a mixer, allowing you to evaluate the application before investing in any connection hardware.
