I took my build in a slightly different direction than others I've seen. Rather than having standard MIDI ports, my custom PCB connects directly to the DB15 Joystick/MIDI connector on most old PC sound cards. I included a joystick passthrough so I can continue to use my joystick by connecting it to …

SOLVED! Not magic! I had my joystick plugged in the whole time, and it rudely shorts pin 12 (MIDI OUT) to ground. When I said "I didn't make any changes" what I really meant was "I unplugged my joystick." Since the wave table and external MIDI both share that same line, having the joystick plugged …

...and it magically started working today. The wave table output is on the "synth" volume slider mixed in with the OPL3 output. Without any driver changes or any other changes, it... just started working. Sigh.

The diagnostic tool checks out, but they don't check MIDI. On the theory that AST had a specially modified CS4232C.EXE, I tracked down an original driver disk image from the Internet Archive and used those drivers, to no avail. I guess I'll give up on this and build an external module to connect to …

Thanks for the links. Yes, that's my chip. Yes, those are exactly the drivers I am using to initialize the card. My CS4232.ini file is stock, as found in that cwd_dos.zip archive. There is no FDAC_SRC option. It does work in windows. Does anyone have these chips and has this working under DOS? …

I believe FDAC_SRC is a setting found in SOUND16.CFG for Opti chipsets, isn't it? This is a CS4232 chipset, so it doesn't have that file or setting. This is the first card I've come across that combines CS4232 chipset with QS700 wave table. Does the CS4232 have an equivalent setting?

Hello! I have an AST Advantage 826 with a built-in sound card. It's a Crystal CS4232 with a real OPL3 on the motherboard. A ribbon cable connects the motherboard to a second daughterboard containing the wave-table capability built with QDSP QS700 and LGS GMS80C501. It's not a standard waveblaster- …
