But as to Yamaha having exclusive rights to FM synthesis: didn't several of Ensoniq's chips allow for the oscillators to be used for producing FM synthesis (as well as additive and plain sample-based synthesis). Additionally, I'm positive that Flare Technology's 1988 "Slipstream" arcade/console/ …

...what about the pre-CQM ASIC implementations of OPL3 used on many Creative cards... This was definitively answered here, as specifically relates to the CT1747: http://www.vogons.org/viewtopic.php?t=32001 ... I'd have to guess that CQM was developed as a cost saving measure that worked around …

I imagine you're trying to use TSLCDR.SYS? This driver relies on MVSOUND.SYS being loaded first, so the CONFIG.SYS entries, and order, would need to look similar to the following: DEVICEHIGH=C:\PROAUDIO\MVSOUND.SYS D:3 Q:5 S:1,220,1,7 M:0 J:0 T:1 DEVICEHIGH=C:\TSCSI\TSLCDR.SYS /D:SCSICD /P3 …

Hmm, I wonder if I have the right software. PAS.EXE on my system isn't graphical. You did use the asterisk, right? ;) Also, just for grins, try adding "t:1" to the end of the MVSOUND.SYS line in your CONFIG.SYS file. This tells the card to use its onboard crystal for the OPL3, rather than the …

All of the PAS16/variants I've encountered have an ever-present, high-pitched whine in the FM output. Whether this is due to inadequate filtering, or otherwise poor design, I couldn't say, but the simple solution is to turn down the FM volume to a level where this noise isn't as noticeable.

I'm writing an NSF player -- y'know, Nintendo music -- for the Tandy 1000 and IBM PCjr. So far this has worked splendidly except for one thing: the SN76489 kinda sucks at being a 2A03. Not only do the squares have no duty cycle and triangles are not possible, the bottom octave is missing. For the …

Here is another example of stellar Asian OPL2 FM work. A number of the pieces are fairly simplistic, but the blending of synth and traditional Japanese instruments was pulled-off to rather exceptional effect, especially given the medium to work with.

Did you have any trouble setting up the SCSI floptical drive? The Trantor SCSI adapter I'm using lacks BIOS support for Floptical drives, so I'm relying on Adaptec's ASPIDISK.SYS driver. No troubles though - the drive itself behaves nicely, and the regular DOS format commands cooperate with it as …

How do you know that? All AWE64s do have CQM, as far as I'm aware. You'll notice that I specifically quoted the statement regarding the CT1747 chip. You'll find that in that same QuestStudios thread, I'd initially assumed that the CT1747 contained an OPL3 core, given the fact that the later CT1747 …

I was referring to CT1747. I don't know why leilei thought I was referring to CQM when that isn't even being demoed in the video. Probably your "Creatives version" wording, which generally implies CQM. OPL3 vs CT1747 comparisons are a bit pointless, in any event, since the latter chips contain …
