I like the RGB matrix function on QLC+ but I do not have a large led display to show the output. I had the idea of outputting to a large screen TV display instead. I achieved this by using the great little TouchOSC alternative, LEMUR, on an iPAD, driven by MIDI. iPAD to TV is then easy.
The results are attached. LEMUR is limited to a 16x16 matrix. The examples show a 16x16 driven by QLC+. I also doubled up to create a 16x16x2 display.
I plan to create a much bigger matrix using multiple LEMUR pad grids.
