aleksej Member Joined: 2006-04-30 Posts: 212 Location: moscow	I have read many times on this forum about "hanging notes" bug with midi routing through "fake" mpu-401 interface on creative sound blaster cards with dsp later than 4.05 Is there exist any solid test (maybe some midi playback) for 100% catching this bug and note for myself that this card is in black-list? I ask for it because some times ago i collect various awe32 revisions for catching very similar bug with midi hanging notes. All awe32 have dsp 4.13 as i know but some models was bug-free in my opinion. I have one dumb test for this purpose. Now i want to know - is there any ultimate strong test for this bug? Where is appear always and constantly? _________________ iBASE MB800H \| P4 3.06ghz \| 2gb PC2700 \| Palit GF 6800GS 256mb AGP Live! \| AWE64G 28mb \| GUS ACE 1mb \| SCC-1 \| MT-32 \| MU10 \| Covox Vanilla DOOM multiplayer across the internet in W9x / pure DOS.

Maybe better is extract this Hexen map02 midi and attach there? _________________ iBASE MB800H \| P4 3.06ghz \| 2gb PC2700 \| Palit GF 6800GS 256mb AGP Live! \| AWE64G 28mb \| GUS ACE 1mb \| SCC-1 \| MT-32 \| MU10 \| Covox Vanilla DOOM multiplayer across the internet in W9x / pure DOS.

I've seen the thread where you explain the problem you had with the game Hocus Pocus. You are one of the few (only?) who actually tests instead of talking about a bug no definite test seems to be available for. I am not saying there is no bug, but until someone tests a lot of cards (like you did in the other thread) in a lot of different configurations, instead of preferring armchair speculation, there is no solid evidence for it.

In the music of the first level (E1M1), the hanging notes are very apparent and cannot be overheard. These are the cards I tested (with both SCB-55 and WaveBlaster I): CT1750, DSP 4.11 - hanging notes (scarce) CT1759, DSP 4.05 - OK CT2910, DSP 4.13 - hanging notes CT2960, DSP 4.13 - hanging notes CT3980, DSP 4.13 - OK I got the last card (AWE32) today and I didn't expect it to work without hanging notes, since it also has the v4.13 DSP, but apparently it does. _________________ 486 DX4 \| 486SP3 \| 64MB FPM \| S3 Virge GX \| AWE32 + DB50XG \| GUS \| SCC-1 \| LAPC-I K6-3+ \| P5A \| 256MB SDR \| Voodoo5 \| AWE32 + SCB-55 \| GUS PnP A64 \| AV8 \| 2048MB DDR \| Radeon 9800 Pro \| ALC658D

However, DSPs 4.13 seem to have a better chance of working fine than 4.11 or 4.12. The card is also a factor here as well. c.imp also said in his other post on the subject: Quote: CT2760: midi - corrupted, fm after emu8k wt- mute CT3900: midi - ok, fm after emu8k wt - mute CT3980: midi - ok, fm after emu8k wt - mute, Qsound 3D on/off - always on CT3990: midi - corrupted, fm after emu8k wt - ok, Qsound 3D on/off - ok I think that if you want an AWE that doesn't suffer from this problem, you must go with the 3900 or 3980. I read somewhere that the SB16 had problems with 8-bit digital sound, leading to cracks and pops. Maybe the later DSP revisions fixed that at the expense of the midi. Finally, to respond to the complaints, Creative did something with the board to fix the midi.

Unfortunatelly even with these two bug-free AWE32 revs. similar "hang note" bug exist but now it have phantom behavior and appears occasionally. In example - it may appear after long playing (20-30m) same midi song during play game. Maybe it bacause of extremal overclocking in my rig (83mhz FSB/ 20.7mhz 16bit ISA) and cards just heat up? _________________ iBASE MB800H \| P4 3.06ghz \| 2gb PC2700 \| Palit GF 6800GS 256mb AGP Live! \| AWE64G 28mb \| GUS ACE 1mb \| SCC-1 \| MT-32 \| MU10 \| Covox Vanilla DOOM multiplayer across the internet in W9x / pure DOS.

I'm surprised that the ISA cards work at all! The 16-bit ISA bus is supposed to be run from 6MHz to 8.33Mhz. The bus may be getting ahead of the card. Try playing without the computer overclocked and you may see that hanging note bug disappear. What kind of processor are you using anyway?

What about the other chips? Could the problems with v4.1x just be a coincidence? It seems strange that the bug vanishes on the CT3980, it has exactly the same DSP as the CT2910 (I can't tell with the 2960, since it's an all-integrated Vibra16C). When I look at all the chips, it seems to boil down to the following: CT1746B + CT1741v405 = OK CT1746B + CT1741v411 = Bug CT1746B + CT1741v413 = Bug CT1705B + CT1741v413 = OK Can someone verify this? Here I assume that CT1746B and CT1705 basically do the same thing, judging from their position on the board. c.imp wrote: Maybe it bacause of extremal overclocking in my rig (83mhz FSB/ 20.7mhz 16bit ISA) and cards just heat up? Although Intel 430xx chipsets do not have selectable clock dividers for the PCI bus, the ISA bus is decoupled from FSB. (I also ran HX and TX chipsets at 83 MHz ) It's extremely unlikely that an ISA SoundBlaster still works at 20+ MHz. Most of them already have problems at 12-16 MHz. I destroyed two AWE64 Gold cards at 16 MHz until I found that out _________________ 486 DX4 \| 486SP3 \| 64MB FPM \| S3 Virge GX \| AWE32 + DB50XG \| GUS \| SCC-1 \| LAPC-I K6-3+ \| P5A \| 256MB SDR \| Voodoo5 \| AWE32 + SCB-55 \| GUS PnP A64 \| AV8 \| 2048MB DDR \| Radeon 9800 Pro \| ALC658D

aleksej Member Joined: 2006-04-30 Posts: 212 Location: moscow	Ofcourse is my mistake - default ISA bus clock is 8mhz not 16mhz, then if my FSB 83mhz i have ISA clock 10.3mhz Anyway this is enough for make many old ISA cards non-worked. In example: My Matrox Millenium II work solid only with 75mhz FSB / 37,5 PCI. With 41mhz PCI he lock up with cyrillic font driver loaded when with 33/37.5mhz all ok. Roland SCC-1 just lock up with any FSB/ISA clock higher than default - very old card Now i set all my cards wich i have in my rig that work just fine on FSB 83mhz. _________________ iBASE MB800H \| P4 3.06ghz \| 2gb PC2700 \| Palit GF 6800GS 256mb AGP Live! \| AWE64G 28mb \| GUS ACE 1mb \| SCC-1 \| MT-32 \| MU10 \| Covox Vanilla DOOM multiplayer across the internet in W9x / pure DOS.

One finds lists documenting the various videocards and soundcards, tested and not-tested, and their quirks when using the software So, I wonder, are there any games out there that list this problem in the readme? Or even better, has anyone ever seen a PC magazine in the day documenting this problem, or receiving letters about it and placing it in the mail section? There must have been numerous people experiencing this problem in the day. Or was the amount of people using the waveblaster connector rather slim? Or perhaps there was a massive conspiracy on the part of the PC magazine editors funded by Creative, heh?

It may be used as a dumb test for first time. Do you have hexen? If not you may download demo version here. launch it with -warp 02 parameter. "hexen.exe -warp 02". Right in begining when game starts (not in loading screen) you must hear (or not hear fortunatelly) hanging note. _________________ iBASE MB800H \| P4 3.06ghz \| 2gb PC2700 \| Palit GF 6800GS 256mb AGP Live! \| AWE64G 28mb \| GUS ACE 1mb \| SCC-1 \| MT-32 \| MU10 \| Covox Vanilla DOOM multiplayer across the internet in W9x / pure DOS.

Just for knowing reason - necessary a game itself or not? Maybe enough only midi file for testing.
