[sdiy] I think I found R2D2....

[Bob Weigel]

Hehe.   I've never see this organ before.  Yamaha DK-40 from 1976.  This 
thing has the ribbon strip similar to the CS80 and 60.  But it's not a 
pitch bender.  It's a theramin more like.  With a handfull of presets 
including the great yamaha ring mod.  But you can play that thing with 
your fingers to make R2D2 come to life!  It has a little keyboard for 
monosynth on top and two manuals that sound awesome.  All transistor 
based of course... -Bob
