I followed this tutorial myself and it even works great in Live Intro. Pretty cool idea and I would have never figured this out on my own. I’m working on using the nanoKONTROL as a hardware interface to it, once I get that figured out I’ll make my own vid and post it.
Step sequencers are are really cool for live stuff since you can modify beats and rhythms in real time. You can easily take this idea and map midi controls to the different steps for all kinds of cool possibilities.
