My thought is to do this primarily on the ARM / Linux side. Virtual controller in Linux that can send commands like a real controller. Network service to receive controller inputs from remote player. There may be existing Linux projects to do both of those things already. This would be the solution. Transmitting the screen and commands over networ...

This looks so cool.

But honestly, I doubt the FPGA core will be as fast as the ARM side for driving the conversion. If you can't do it elegantly, do it with horsepower.

Also, if arm side, or with a separate post processor, you won't have to do this for every core.

How does your mt32 pi do downstream audio mixing? Do you need to disconnect stuff when you change to a non-midi core?

Alpha434

Sure does, and I guess rhester72 meant the ARM on the MiSTer. That's quite underpowered compared to the later Pi iterations. My Pi4B runs MUNT without breaking a sweat, plays the intro to Space Quest III without a hitch. Compared to a real MT-32 it even sounds less noisy. I do understand the mister's arm processor is limited. Maybe it's a daughter...

ARM isn't viable - even overclocked, software MUNT results in very noticeable dropouts, which is how the user port solution came to be in the first place. You hit a LE wall (and noticeable absence of any FPGA code!) trying to do it in-core (because it would have to sit astride the actual core you want to use it), which is why I don't think it can ...

Why would midi require or even benefit from FPGA simulation? Sure audio is timing sensitive but is there really that much there in old synth modules that a recent Pi wouldn't handle just as accurately? You're not really getting analogue synth hardware from an FPGA anyway, right? Of course you're correct, hence the MT32-pi. I think the concept here...

Nukeykt is working on a low-level MT32 emulator similar to Nuked-SC55.

This might be better if you can't get MIDI to fit on the FPGA core if you can get the emulation into the Mister operating system instead.

How many components is the MT-32?

Hello, new member here. Also a relatively new MiSTer user, with just a couple months under my belt. Not sure about gate array size or other system limitations, but I had the idea of adding a midi device to the audio output leg of applicable system cores. Once the MIDI device core is mapped, it may be easier to implement into the correct cores. I li...
