live performances with no glitches. Slight buzz on piano decay but it's still

the best piano for the money!

Lots of programing depth. You'll never get to the end.

Avoid VFX models since they have a split circuit board that

bends in the middle after sitting on stand for awhile with unpredicatable

sonic results and frequent operating system re-initiations.

This unit is a winner at used price of ~$700 American.

to use, excellent sound quality machine. For someone that just enjoys rich

full stereo instruments and beds, with the simplicity of laying down upto

16 tracks as if you're using a tape machine, nothing comes near the SD-1.

The large, interactive display is what makes this keyboard so fun to use,

and is unlike any other keyboard display past and present. You don't need a

computer with this keyboard--it's already got enough power and capability

on its own. I do agree the you can get lost in the programming parameters,

but for subtle changes to existing patches, it's there if you want it. I have yet

to tap all the creative aspects of this keyboard, and probably never will. As

the heart of my system, I'll never part with this gem until it dies on its own.

You can still get patches from Syntaur, Kid Nepro, and other smaller outfits.

display. However, I have owned one for years and found it has one of the

most powerful on-board sequencers from my pre-computer days. It tends to be

a bit "buggy" with its software-based O.S., but it was always fixable with a

reboot. The machine is also quite intuitive as a workstation. Most of the

sounds are remnants from the very "digital" late 80s sounds, but they, too,

will be resurrected. Oh, the snare sounds are killer with the "timbre" pushed

up and the effects dry. The on-board effects are a bit noisy for my tastes.
