Recived my MP32L last week, thanks for fast shipping dreamblaster!
There seems to be still total component blacout in world, everywhere i looked, no Raspberries available.
Has anyone tested MP32L on Raspberry Pi 2b? I did not find any info regarding MP32L on RP2b, so i decided to try out. So i dismantled my home server running on RP 2b. Prepared SD card and config file... and it kinda works! Boots up very fast, music sounds on General MIDI mode games very good. But older games, that support only MP32 sound kinda off. I mean like wrong instruments are used. Tested with old version MP32 and CM32 roms. Can anyone tell me where is the problem?

Does your sound card support MPU401 intelligent mode?

No, i use a cheap-o cristal chipset based SB clone + softmpu. For comparision i have an original old version MP32 running next to MP32L.

Your issue sounds like SoftMPU is not working, or your computer is not managing to upload data to the MT32-Pi. This could be a problem with the USB MIDI interface you are using. What brand/model is it?

I use it on my 486 PC at the moment , so no USB cable but MP32L directly hooked with Midi cable to sound card Joystic port.
I have also that cheap chinese USB MIDI cable somwhere lying around too, if i find it will give it a try.

I'm a pretty happy CM32-L owner at the moment.

One word of advice is that the small posts at the bottom of the case may need a little trimming, your Pi board should mount onto those holes, they aren't simply spacers. Took me a while to figure out why my case wouldn't go together properly.

I have not yet found good quality screenshot of PCB in order to ID DAC chip on MP32L. Owners here, could you share this info. Product page is describing it as "High quality DAC" and that's all.
