Well well well Andy - biiig congratulation!
I got the SK20 myself - and what can I say, it`s
the only hardware poly I got left (besides the
TX7)and it will never ever leave. Why? For the very same reason as you describe - the SK´s are just incredible sounding machines! I love the organ section as much as the string and the synth sections - the organ is actually based on Yamaha`s original FM technology, like in the GS series.
I got my SK modified with a CV filter input, so
now I can control the filter with a Moogerfooger CP251 control processor...pretty great!
I wish you many many great hours with your "new"
great keyboard Andy!!!
