I own a Midiman MM-401, and have been using it to output to my MT-32 (old) and GM modules. In my particular situation, using an MT-32 (OLD) on a newer system (K6-2 500), it seems likely that I will run into speed related issues with my MT32 in some games. Will SoftMPU fix this problem with the /DELAYSYSEX switch?
If so, am I gaining anything at all by using the Midiman as opposed to any other MPU-401 interface? I know these cards are quite rare and pretty valuable, since they generally work well without SoftMPU, but... if SoftMPU can still improve compatibility of the Midiman, is there any reason I shouldn't just switch to using the MPU-401 interface on another card, like an AWE64 Gold or YMF719? SoftMPU seems to pass all the tests that people put it through.
On that same note, what would be the limitation of SoftMPU? What systems would it be unsuitable for? I've read that EMM386 is required, so presumably a 286 or 8088 would be too old to use it, but what about an actual 386 or 486? I'm just trying to determine if there's any reason at all to seek out intelligent MPU-401 interfaces like this Midiman card, now that SoftMPU is so good.
Does your MT-32 (Old) display either of these messages?
- Code: Select all
Exc. Buffer Overflow
Exc. Checksum Error
If Exc. Buffer Overflow, either press Master Volume and number 4 (Overflow Assign?) 1 for yes or 2 for no, or as you suggested, run SoftMPU with the following command:
- Code: Select all
softmpu /sb:220 /irq:5 /mpu:330 /delaysysex
***NOTE:*** replace the /sb /irq and /mpu with your configuration on both your sound card and MPU-401 Intelligent card
If Exc. Checksum error, either disable your cache or run a slowdown program, like MoSlo (I use MoSlo for NHL Hockey 95 and it almost works). Either that or purchase a Roland UM-ONE mkii USB MIDI adapter, install Munt
onto your computer, obtain the ROM files (PCM and CONTROL) for the MT-32 and CM-32L, install the MIDI driver in Munt, plug in the cable that says "Plug into MIDI out" into the MPU-401's MIDI-OUT.
Also, keep in mind the Midiman MM-401 doesn't work with Legend Entertainment games, like Frederik Pohl's Gateway for example. I have a Music Quest PC-MIDI IH9MQ9 clone card that is 100% Roland MPU-4o1 compatible, and NHL Hockey 95 doesn't have the right instruments/notes on my MT-32 (Old) since it gives me Exc. Checksum errors across the room.
