[sdiy] Yamaha PSS460 users?

[Joe Kramer]

Dear Harry,
    Thanks!  The DX-7 reference was a helpful clue.  Consequently I found this DX-7
site and learned a lot:
http://www.geocities.com/SunsetStrip/Lounge/2133/dx7_tx7.html .  I guess the PSS460
is my accidental introduction the the wonders of FM synthesis.  I'm hooked!  Now to
feed my MS20 some high frequency sine waves. . . .

Regards,
Joe Kramer
