Re: Sierra/Dynamix sound driver hacking

Been awhile since I got a chance to do any serious retro related work. I forget what I did to "fix" / "workaround" the Rama sound silence bug but everything plays - have to try on KQ7 to see if it fixes the gargoyle freeze / kitchen mouse sfx bugs there. Lowering the dacsize introduces the sometimes …

Thanks - did not know that or paid close attention about Duke3D. Going to listen to the AWE64 results later. Debugging Rama is so annoying. I think I found the pseudo-bug where it refuses to start new audio tracks though - hope to get that working (incredibly annoying bug, whether Dosbox fault or …

Strife has no GS percussion. But 1 drum CTF D_SLIDE.mus ; CTF = Jazz [000019] C9 26 [00001C] 99 29 51 [00001F] B9 0A 32 [000022] 99 24 63 [000025] 99 26 43 Track has 1 instrument - percussion channel only. So it looks intentional enough. So Hexen + Strife are now added to patcher. But there's this …

Checked all of VSC documentation and nothing about drum kits 70h - 73h. Just 7Fh = CM-64 / 32L. I'll remap it to STANDARD. Drum kit is hard-coded into the physical MIDI score itself. It's the only one in any Doom-engine game so far. (Raptor: Call of the Shadows = plain GM) GROVER.mid uses ch1-8 + …

what is meant with this combination? I don't know. It's what NewRisingSun said once in the Sierra thread when I asked about his SQ5 driver. So I only know based on that - I take his word that it exists but don't know how it sounds / works. xx( For Hexen, type this: visit11 https://doom.wikia.com/ …

SC-88 has that 'No instrument' message when using melodic CTF. I wonder if it does the same thing with 'bad' drumkits (no percussion plays)? Or does this special drumkit even exist on SC-88? To be more precise, does the percussion sound the same on SC-88 vs SC-55 non-GM vs Yamaha when using this …

I checked the mirsoft MIDIs. They look wrong - zero program changes once score starts. Doom 2 raw recordings have lots of patch modifications mid-track. There's just 1 soundtrack that covers both FM + MIDI.

Check around 1:32 for D_DM2INT. You'll see program change and there should be around 6 hits total from then on. http://www.doom.com.hr/public/doom2/music/midi/ Thanks for the D_OPENIN info. Problem is going to be... how to fix this? Unless there's a bank controller I didn't see. And then patching …

Did some RAMA - menu, plenty of interview clips, prologue, new game sequence. I'm surprised that the menu, logo, interviews, prologue turned out okay on default settings. But the new game is a big hit / miss - some plays it's mostly okay with some audio glitches. Other times it's partly pop, crackle …

Not yet. 🙁 I've got a small idea but couldn't get around to actually playing to see what happens. I do have it installed and just sitting around. 😐 - Thanks for reminding me though. I'll mark it as a higher priority.

Feels like ages have gone bye. Doing Descent I+II in piece-meal as I get time. Copy patcher tool to . Run and it will patch MIDIs only to be Fl. Keyclick friendly. Be sure to make backups of your DESCENT.HOG / DESCENT2.HOG files first.

Probably going to have to make my own patcher. xdelta is too rigid - exact hashsums - and others don't allow flexibility that I'd like. I don't remember Descent GUS having custom percussion samples. But we could check anyway. Didn't know that System Shock uses a few custom patches.
