If you are creating your own test module, just take some noisy sample like a crash cymbal or a power snare with lots of reverb. Play it back at a very low pitch or resample it in Scream Tracker if you know how to do that. If the playback routine uses the GF1 chip it will generally sound much more …

If the software is sufficiently old, it is very easy to determine if a software uses hardware mixing or not. Software mixing was always done without interpolation in the early days because a 486 couldn’t cope with > 16 channels and achieve the same quality as a hardware mixing device. If you use a …

You could try to use the UNISOUND utility to initialize your SB in DOS, it is discussed on this forum. Also, my experience is that you always have to run DIAGNOSE /S (if you don’t use UNISOUND) in DOS. Did you use CTCU to set the resources of the SB?

I was about to say the same. I first searched for the Maker Hart mixers, but they are not available in my region. Then I found this one, but the PDF specsheet (https://images.static-thomann.de/pics/atg/atgdata/document/specs/180444_specs.pdf) says it sums the RCA inputs, and the scematic also shows …

Unfortunately, when I disable the AWE64 again it still says "There is no 8019 PnP card on your system" and every tool I try that doesn't crash can't find the card anymore (I tried AIDA16, NSSI and HWINFO). No, it happens both with unisound and the creative software, but I had silently hoped that …

No, it happens both with unisound and the creative software, but I had silently hoped that unisound did something different😉. Anyway, I don’t know how I can fix it, as they clearly seem to have different resources when initialized in DOS and they also work happily together in Windows 95.

It depends on taste also. I’ve never liked the first low-poly games, I just found the characters ugly looking. And without a 3dfx those games didn’t run very well and looked even more ugly. When I (and my friends) finally had a PC that was fast enough, the quality of the 3D graphics had grown quite …

Uninstall feature sounds like a great idea, because in my 486, as soon as I initialize my AWE64, my RTL8019 network card (that does NOT share any resource with it) is not recognized anymore by the DOS drivers, not even after a soft reboot. Only a hard reset will enable it again, or booting into …

It seems it isn’t only the CPU emulation that determines the performance of DOSBox. Some VGA operations seem to be much quicker than a real system. For example, the TOPBENCH video score is a few micro seconds, way less than any real video card I have can do. Also DOOM seems to run very fast for the …

Okay, well I notice with my GUSpnp that after certain programs (mainly demo's) that maybe don't exit clean, that after that samples sound staticcy (if that is a word) or that the loop points are not accurate. Especially with smooth samples like sine waves or pads you hear tics at the loop points …

The problem with that idea is that many of those are likely the revision with the "distortion bug". This appears to have been corrected in a later revision of the silicon, and those are the chips one wants when building a new InterWave-based device. May I ask what that distortion bug was? Were …

Great. Anyway, one more question... if you run Unisound again (a 2nd time) after the CQM left-channel issue, is it fixed? I ask that because there is a known issue between most games/programs supporting AWE synth and AWE64 / late SB32/AWE32 cards. After using EMU8K synth in that games/progs, then, …

Hmmm, that's weird... I checked v0.70c with my CT4520 and It worked well, both channels work (CQM), tested in: Descent, Tie Fighter, Dark Forces, SSF2T. Did a previous Unisound version work well for you? in that case, which one? What game/program did you test? What are your system specs? I am sorry …

I have a strange bug with the latest version of Unisound and my AWE64 Value. While the wavetable sounds just fine, the CQM synth is only audible on the left channel. As they share the same mixer input, I don’t know how to fix that. If I just use the Creative tools (diagnose and aweutil) it sounds …

Isn't it true that the OPL chip uses a quarter sine wave stored in ROM to generate the 4 basic oscillator modes? So, "technically", an OPL2 chip is a "wavetable" synthesizer 😊

I can also add from experience that the CF170 has the fixed disk bit set, and operates as a normal IDE disk. For me, the 16GB CF170 card has worked for over a year in my MS-DOS retro PC, but that is of course no long term guarantee. 😉

As far as music goes, it doesn't even need to be realtime, you can generate any amount of data ahead of time since you always know what music data is needing to be written in the chip and can render ahead a stream that you then play back. I think he means that Wolf3D also uses OPL partially for the …

Got rid of a 17” and 19” Iiyama trinitron CRT because I had moved to TFTs and they were too large and heavy to keep around at the time (I was a student at the time). Surely regret it now, my current CRT isn’t nearly as good as they were.
