I've read about this several places on this forum but can anyone give an example of a specific game or situation that would work best for testing the hanging\dropped notes issue with the PAS16's MPU401 emulation? I recently received a somewhat less common PAS16 variant, the IXW-MEMPHIS, which connects directly to the Media Vision Memphis multimedia speaker\CDROM system with a 44pin cable (no audio jacks on the card, but there's a ton on the Memphis unit). I tested it briefly in Windows98SE because of the built in drivers and using the add new hardware wizard it installed it as a PAS16 with SCSI. The MPU401 interface seems to work normally when hooked up to my Roland SC55 (via the MIDI output on the Memphis unit), but I've only tried a couple different things under Windows 98SE. I did have some issue with the digital audio dropping out periodically in one game (Captain CLAW demo) but this happened whether the MPU401 or OPL3 were being used for music, and a Windows game from 1997 is hardly the target use for a PAS16... it just happens to be something that's installed on my tester system.
If anyone has experienced these issues with a PAS16 in the past, I'd just like to know in what games and under what circumstances they experienced issues. If a recording exists of the issue that would be incredibly helpful, since it can be hard to tell what notes are out of place if I haven't heard a given MIDI track recently.
EDIT: Some discussion of the issue from around Vogons:
486 and Roland MT32
PAS16 sounds distorted
Plus a very short anecdote to simply avoid using MPU401 on the PAS16 from Nerdly Pleasures:

Other than that, I haven't found much information on the subject.
Now for some blitting from the back buffer.
