I have an IBM Thinkpad 486 w win95 which I'm very happy using for midi playback My problem is I am looking to buy a sound module (I was using an opcode into a sv88), which is bit irrelevant ). Do I have to spend up to 500. bucks for a new one? or have prices come down somewhere in cyberworld.? What are the big differences in the newer models ( say roland 1080 for eg.) and say one a couple years earlier?Do people sell used sound modules?
