Yes, i'm late to the party, but i have some questions.
i've been using lsdj, an arduinoboy, and an EMX-1 with midi mode for a while now, juts sending start/stop messages to lsdj from the EMX.
Now that i have learned about midiout mode i have been playing with it, it all makes sense and is a lot of fun.
The thing i'm curious about is what do people think is the best way to trigger/program drums?
i'm kind of thinking i'll make noise percussion and set my drum machine to midi channel 4...
