unnamed subterm is serious. i think only the last one created gets

  saved, or something

OK  KC smaller font on labels should allow bigger sliders

  curvecalc_all_subterms needs redo

  touched dmx cable; ~/dmxcrash in dmesg; process went to 'D' status; rebooted

  a nice startup would be: take a cd, boot up our OS image, make a new

  show from the cd tracks, UI for naming the channel numbers.
