for a CD about electronics for artists. Although it takes time and effort I
think it's worthwhile learning how to make customised gadgets. It shouldn't
take too long to learn how to put together a few switches and/or radio
receivers and transmitters as well as simple sensors. Too late for your
present show but a good investment for the future.

The PIC microcontroller seems to me (a mere musician) to be a bit
complicated but I'm planning looking at all that stuff once I've got a
handle on the basics.

As for sync'ing the mp3 players I recently got 8 members of the public to
press "play" simultaneously on portable CD players to kick off an 8 channel
piece. An easy solution which also gives people a stake in the work. Good
