If you are of a certain age you would be familiar that the peak computer audio experience was the Roland MT-32 midi processor. This was when PCM audio took up lots of space so music was stored in midi format and processed by software or output to a midi device. When games started to be released on CD-ROM, developers favored audio recordings over midi compositions and devices like the MT-32 were no longer needed. These days the MT-32 can be software emulated just like old consoles. But also just like old consoles there are projects to duplicate functionality through hardware. The MT32-Pi project has similar inputs and outputs as the original Roland. The digital processing side I don't think needs the FPGA treatment like MiSTer. DA side could use some attention. The original specs for the Roland show that the output was with pcm54 chips, a 16bit ladder DAC. I happen to have a Modi MB…which is a 16 bit R2R DAC! Whenever I have the time and resources I would like to build this MT32-Pi + SPDIF out + Modi MB and compare to the software emulation supplied by ScummVM or original MT-32 if I can get my hands on it. edit: reading a bit more about the MT-32 and it doesn't seem as simple as just using an R2R DAC. After the DA stage there's some analog post-processing which contributes to a signal decay. Depends on what the MT32-Pi can do but I think its safe to say nothing will sound quite like the original. I have quite a few people in my retrogame group that have an MT-32 in their setups. I asked what speakers they used and most of them use Logitech. I just came across this vid from the youtube algo. He shows side by side comparisons and OSSC looks like a good device.
