Hi Han (Lukitoh): I too fondly recall the 01/W as I too owned one (actually the 01/W FD version, of which included a built in floppy drive). The 01/W FD:
was my second foray into synth ownership, my 1st being the futuristic looking Korg 707:
The 01/W was a terrific sounding keyboard for its time (circa 1990) . I distinctly remember the acoustic piano to be an impressive improvement over the Korg M1 predesesor. Though the 01/W is still perhaps a capable keyboard, by today's standards, it pales in comparison with (both in sound quality & features) todays leading synth workstations. Han, thanks for bringing back my fond Korg sound memories, and which is perhaps the reason, I consider getting a Korg PA1/X now. - Scott
