The Kawai & Teisco Analog Synths Group

Hi all,

new member here. I'm interested in getting one of the SX synths, as an
addition to the Kawai XD-5, K4 and K5 synths I already own. 

As I understand, the SX-240 is basically an SX-210 with MIDI and a
different panel, right? Are there other differences? 

And the SX-400, is it a (mostly) fully analog version?

I'd prefer to get an SX-240 because of the (basic) MIDI support, but
if there are cool features I can find on one of the other synths, that
might change.

Cheers,
Antoine
