I had read an earlier post about creating an X0X style drum machine. In my opinion I think this would be totally possible. I was thinking such as how the 505 works. There could be 16 steps of LEDs using the basic Midi Box Seq layout. IF Thorsten might implement the possibilities of lighting LEDs on the clock related to the BPM, the MIDI BOX sequencer should be able to handle the rest. Maybe a future implementation? Got to love MIDI DIY!!!
the application will be written in assembly language for the best performance. A C frontend could be possible, but it’s not planned yet. However, small modifications in the control surface should be possible without much PIC knowledge, for advanced solutions you need to learn the assembly language (but a MIDI project is a really good starting point for this :))
