MOTM

john-  many thanks for your advice and the links.  your suggestions
seem like a real good way to go.  as for the case, for work i am a
finish carpenter so i am looking forward to designing a case for the
system.  i hadn't been thinking too hard about midi-cv converters yet
and am curious to look more into the 650.  sound like it makes sense
to get the 950 rather than the 900.  the 650 has an arpeggiator?  that
is way cool.  

your system looks like fun enjoy it!
