I'll delurk for a minute to say that what Dave has done with the PSIM
is one great way to take this thing (in addition to many of the other
suggestions). Adding MIDI and display capabilities to the "standard"
CVS would be phenomenal improvements over the PSIM.... not to mention
the Speakjet chip ;)
