It is working under windows using the generic microsoft MPU-401 driver. But under port 220! Isn't that a bit strange? The card is in sbmidi mode. Does that mean that i wont be able to connect external midi modules?

Do you have playback under Windows through the MU80 or through the sound card?

The output is ESSMPU(220) and the module is working. Tried FF VII and it picks up midi and XG. The strange thing is that it uses the port address of the sound card (220) and not a regular midi port(3xx)!

That's normal for SB-MIDI.

From the programming guide, section 5-2:

SB-MIDI mode shares the same I/O ports and 8-bit DMA mode interrupt status bit associated with digitized sound. This means that you can access the MIDI port by writing to and reading from the DSP.

Interesting! So in theory setting up softmpu in pure dos using the port and irq of the sound card (220 & 7) should have given me output? And what port should i choose in games? They range to 3xx. Am I missing something?

Are you using the ENMPU.EXE TSR that ES688 requires for using the MPU401?

Yes i have. But using port 330 and irq 9. It will load but the midi port wont be detected by games.

The TSR may be defaulting to IRQ2? I have a few Non-PnP ES688 cards and none of them allow me to actually change the MPU401 Port or IRQ via jumpers, they are hardwired to 330/2 IIRC.

I will give it a shot.

Got it to work using the jumpers on sbmidi and running softmpu /mpu:330 /sb:220 /irq:7 :/output:sbmidi
Works with some older games (clouds/darkside of Xeen, cannon fodder) but breaks many others. The ENMPU.EXE does nothing at all.
