Edirol V-8 MIDI Tally Interface

Testing code, with a Sparkfun MIDI Shield and 16x2 LCD display

Roland Edirol V-8 is a basic VJ video mixer, in a standard DJ mixer format and does the job for mixing between 8 video sources.

The V-8 doesn’t have a Tally light interface, but it does have MIDI out.

Using an Arduino, Sparkfun MIDI Shield I already had, and Tim Twillman’s Arduino MIDI library, it was fairly straight forward to check the MIDI Control Change messages.

Using a series of IF statements, that would keep an eye on which input buttons had been pushed and was position the Transition bar was in (all the way left/centre/all way right).
