Are they playing an instrument, or are they doing 50 push-ups?
If only one could cheat and NOT really do it, but somehow use technology to achieve the same sound, so anyone could do it, if only there was a device that could , oh I dont know, record what you play and repeat it at odd timings, so you didn't have to... that would be wonderful!not sure I've understand your point here, Mark, but I'm almost sure that technology will allow that in the future and I would try that for sure (I'd like a sort of "generative odd time signature software...lot of fun !).
