Ive seen heaps of videos of people using these in completely the wrong way, in the right hands things can be pretty useful, but using them as a step sequencer as alot of people do leaves a lot to be desired IMHO.
All Monome Youtube videos sound like variations on this one to me:
A self congratulatory masturbatory f*ckin’ racket. I haven’t seen anyone use one to do anything that couldn’t be done in 3 minutes with the tracker editor in Fruityloops. It’s such a beautiful device, but it’s really a solution looking for a problem.
I’m sure someone will figure it out eventually, and I’ll bet the answer will be something along the lines of “If you add a box of sliders and knobs for your right hand and use it with the Monome you can do… THIS!”
