Making an astute prediction: Once you all hear it, your apprehensions
will subside.  The MOdel 30 not only behaves like it's analog brethren
as far as the user experience - the interface, it sounds remarkably
analog as well.  

We must remember the big part of the DX wasnot only the operator architecture, but the manner in which it handled polyphony.  This took a big toll on the it's richness.  They weren't fat.  The MOdel 30 doesn't have these issues.  Imagine that marvelous phase cancellation caused by two slightly detuned analog oscillators. We know this sound.  Now imagine that phase cycle being a minute long. These are the types of advantages digital technology bring to the analog model.

Sound samples will be here soon.

Regarding the select switches, and we must keep in mind that the MOdel
30 is still in development and being digital, changes can come easily.
But as it stands, the select switches are used in conjunction with the
WAVESHAPE (labeled 'Variable') controls to determine which VCO or
combination of VCOs are effected by manual adjustment or control
voltage of waveshape.

For instance,  if you wish to change the waveshape of VCO 1 alone, you
would depress it's SELECT button, it's LED will light indicating it's
armed and then you could change it's waveshape via the pot or
external VC.  If more than one VCO is selected, which is allowed, then
each individual LED will light and adjustments to the Variable control
will effect them all.

If multiple VCOs are enabled and on the next adjustment you wanted to
change only one of them, depressing the select button of any 
'live' VCO will disarm it.  It's LED would turn off, it would not be affected by the change.
