Fitzcarraldo, you are great.
With you it can always find different ideas for discussion.
I knew Arduino
but probably not enough, because I did not know he had a development system that runs on Linux!
I have some funny experience with Microchip PIC
(using C language and JAL) but have not yet learned to use the USB communication (mea culpa
They also have some very nice Starter Kit
to learn and have fun with microcontrollers.
I also remember a plug-in for XMMS that could control some features ...
I have to go searching through my old stuff!
TSO is a really interesting musical project (an iron fist in a velvet glove).
I have always loved extreme combinations (ie Royal Philharmonic with Deep Purple...)
