Just scammed me a poly800 II from a pawn shop tonight for $65. I love it. I've done ALOT of research on this piece as well, since I wanted to make sure I was spending my grocery money wisely. I've seen alot of complaints about it losing it's memory without batteries. Well, I don't have ANY batteries installed (except for the little internal battery), programmed some patches, turned it off, taken it apart (power unplugged) and my patches are still there.
Any of you did the filter mod to yours? That'll be my next project. Aside from a broken key, I'm thoroughly happy with this synth for the money I paid for it. It's certainly better than paying double what I paid to get a crappy casio and be stuck with sounds. At least I can program to my hearts content, save my presets to my sampler through the tape out jack, and move on. I haven't quite figured out the step sequencer yet. I know how to get it in the recording mode, but haven't been able to play them back. I don't have a manual.
I've also seen alot of complaints about having to program so much stuff, therefore it being a piece of crap. I see this as being much better than picking up an expensive synth, playing all the "cool" sounding pre-programmed presets in your music, then come to find out you sound just like every other person who chose to just use the easy route.
Well, any help with an online manual, downloadable patches, or the sequencer help would be appreciated. As soon as I get all of my patches programmed, I'll put them online for download.
