When people ask me about the Profiler I always say: "I can record the sound of my amp, but not the music I play, only the sound. So then later I can play new, live music with that recorded sound." I don't know it this is really technically accurate, but it gives them quite an instantaneous idea of how it works.
I hope I will live up to the day when we can profile all kinds of sounds, like on an audio-recorder, and then play with them like malleable samples. Todays samplers sound so rigid, unchangable. To me they always sound a bit like parrots, meticulously repeating the same sound over and over without the ability for variations. Granular synthesis can offer some degree of flexibility but it very soon sounds very digital, artificial.
Wouldn't it be cool to play a guitar solo with the sound of a jet engine, or a tiger or a blackbird?
