FM is actually digital synthesis, though some implementations included analog filters. What the OPL3 produces cannot be any different than what an effective emulation of it can produce. It literally outputs digital data which needs to be converted by an external DAC, which is normally right there on the same board. On the other hand, SID's synthesis is analog, something that really confused me as a 15-year-old trying to make video game sound effects but which I really appreciate today. I think the only reason we don't see more "SID in a box" devices for the increasingly popular chiptune culture is that chiptune composers seem to favor Nintendo devices like the NES and Game Boy. But the SID is much harder to emulate accurately than those, and an external box would really be desirable (if one doesn't find a way to just network a C64 to do it, which may be cheaper). >> But the periodic appearance of hobbyist-level SID-based devices for >> modern PCs indicates you're not the only one with this sort of idea. > I used to think of these devices as hobbyst's things, but (specially > regarding the MOS SID) their demoscene users tend to take some art out > of them. And they actually were designed with a musician's perspective By "hobbyist" I mean "hand made one at a time by hobbyists", as opposed to "mass produced in Chinese factories". It's certainly not a judgment on their quality or the art that one may produce with them. I still have a Commodore 64 myself, and while I'm more than happy enough with emulation of its sound for the most part, I do recognize that analog synthesis does have qualities that simulations of it don't... and vice versa. At any rate, speaking of the hardware SID specifically, what you're looking for is definitely possible... the hardware may still be available: http://amigakit.leamancomputing.com/catalog/product_info.php?products_id=842¤cy=USD but the Linux driver site seems to have disappeared in the last year: http://web.archive.org/web/20130812052953/http://llg.cubic.org/cw/ Rob _______________________________________________ Linux-audio-user mailing list Linux-audio-user@xxxxxxxxxxxxxxxxxxxx http://lists.linuxaudio.org/listinfo/linux-audio-user
