Could someone add the list of known AWE32 model numbers that are bug free to the wiki?

They are already there (in Section Bugged (Type 2 only)). The hanging note bug can still strike on these AWE32 models (I've witnessed it on CT3900 and CT3980), they are just immune to the variant of the bug that occurs in Doom/Hexen/etc...

Ahh, didn't get that part.

So effectively, the only way to use a genuine sound blaster with a daughtercard is to use an early 16. AWE32 gives you half of the problem, and AWE64 avoids it entirely, but you're stuck with no DB header.

Is there a way around the issue of not being able to use a joystick when you have a daughtercard plugged in?

Yup - plug in another card 😊

Well, it's not exactly half of the problem with the AWE32, it's much less than that since the remaining variant of the bug only occurs very rarely.

There shouldn't be an issue with a daughtercard and a joystick being used at the same time. If there is one, you should take a look at the wiring of the joystick.

I always assumed this had something to do with RAM. My daughterboard is a Turtle Beach Rio and it has a slot for some SIPP EDO RAM. Unfortunately, it's expensive on ebay so I can't add more RAM into it to see if that was the issue.

Not sure. I've got my CT2940 with a XR385, and a CH Jetstick plugged into it. The daughtercard gets muted when the joystick is plugged in, but the joystick works just fine when the daughtercard is attached. MIDI seems to be coming out ok when the joystick is plugged in, except that it's 100% silent, muted I guess?

Adding memory to the RIO is completely optional. Memory allows adding some custom samples, that is all. (It is easy to convert a SIMM to a SIPP with some soldering.)

I figured it was probably trivial with soldering. However, it looks like there is only about 30 pins or so and EDO has 72. So, it's not EDO specifically, but the modules on the EDO itself look similar.

Is there no benefit to adding the SIPP if I plan to use it strictly for games?

Most likely it's because the CH Jetstick shorts pin 12 of the gameport to ground. This complies with the original purpose of this pin, but soundcards started to use this pin for MIDI-out, so most joystick don't have this pin connected. It can be fixed by either removing pin 12 on your joystick connector or using a dedicated game port for the stick.

I was just browsing the archived Yamaha site when I found this:

If you are getting stuck notes when playing games this is down to some sound cards using virtual device drivers rather than a genuine MPU401 Compatible midi port. When the games tries to initialise in MPU401 mode, it cannot as the chip is not on the card. This coupled with the drivers that are handling the waveblaster socket, can lead to stuck notes. The Creative Labs update patch to help with this problem is free to download from the Goodies to Download section of this page.

Not sure if it has anything to do with the hanging note problem though.. the readme included with the patch says something completely different:

Sound Blaster MPU401 Fix Version 1.00 Creative Labs, Inc. […]

Sound Blaster MPU401 Fix
Version 1.00
Creative Labs, Inc.
11 June 1993

Description:
------------
SBMPU401 adds support for Creative's MPU401 port to several programs
which currently support Roland's MPU401 cards but fail to work with the
Sound Blaster 16. If you have a Wave Blaster or an external MIDI module
that you wish to use but your computer locks when you select Sound
Blaster Pro digitized sound and MT32 or General MIDI music then this
utility should fix the problem.

Usage:
-------
To enable the fix type SBMPU401 /E.
To disable the fix type SBMPU401 /D.

Here's the link:

Thought I'd just post it here, as I've never seen it mentioned here before. Has anyone ever tried it?

Actually in this very thread I asked this a while ago:
SB16 vs DBs (hanging / stuck / wrong notes in MIDI)

I think it is the same tool you are speaking of.

My Apple-Dos-Card has a Vibra16CL PNP. Does anyone know what Chip/Card that is and if it has the hangingnotesbug.

Thx!

Some Vibra 16C chips are not bugged. I recommend you:
Download NSSI and verify the DSP version
Download the Hexen demo and run hexen -warp 2 after configuring Sound Blaster audio and MIDI music. This will check for type 1 hanging notes.

I realize that I'm responding to a post from 3 years ago, but this may help other people if it's indexed by google, so here's my take on this.

Converting a 30-pin SIMM to a SIPP doesn't even have to involve any soldering. What I did - and this was for a 286 motherboard, but should work the same for a sound card that uses SIPP - was buy a few 30-pin SIMM motherboard connectors (think it was from Jameco), installed each SIMM in a connector and then plugged the SIMM+connectors in the SIPP slots. Works perfectly.
