Can't wait to see that, any eta or pricing idea?

Eta.. not really sure... given my current schedule it will probably be a few weeks before I get the prototype completed. Pricing? Assuming it does actually get to a stable and sale-able state, I would guess sub-$100.

Any updates? Very interested. :)

Ah, sorry, i've been pretty busy so only seem to have a handful of minutes to myself at any given time, so I usually get distracted with something that I think will only take a couple minutes.

I hope to return to this soon and get a couple boards assembled.

I realized though that what I've made (from a hardware perspective, anyway) is more like a fancy MIDI adapter for the OrangePi, and therefore moreso a generic MIDI computer than specific to something like MUNT.

N00b question: if that's the case, how is it going to be different from something like this?

Pisound doesn't connect to the Wave Blaster port on a sound card.

This also won't, it'll be a standalone card with a waveblaster port on it. See this post: viewtopic.php?p=572261#p572261

So effectively, it'll be an internal version of PiSound?

Well, I will admit that (a) I have not heard of this project, and (b) they are very simiar. Both have audio I/O and MIDI I/O to a SomethingPi. The software I develop will probably be as compatible with a Raspberry Pi 2/3 as much as it will be on the OrangrPi for which it is built.

The three main differences that I can think of between PiSound and this project is (1) the form factor -- externally, MB-32 is designed to be in a nice case and emulate the appearance of an MT-32. The I/O ports are all on the back to support this form factor. I have a 3D prototype printer onboard to develop a case. (2) internally, it can/will connect to standard WaveTable header and can operate directly attached to a compatible sound card, and (3) it has an LCD and front panel controller that can be attached when used externally (and therefore emumates the front panel I/O of the MT-32) and used internally (theoretically possible to make a 5-1/4" bay I/O unit for LCD and buttons... I should look into getting the 3D printer to develop this too).

But otherwise, I will concede that basic functionality is the same between the two projects.

My interest in the MB-32 just when from, "neat but I already have a real MT-32" to ludicrous. That sounds really cool. Hopefully the display can have different modes such as spectrum analyzer (FFT) and maybe a mode similar to a SC-55/SC-88.

Thanks for your speedy and extensive response! :)

It wasn't yet clear to me that you're also planning on building an external version and a LCD/front panel (and perhaps even a bay) version. Very, very interested. :)

Would the external version connect to a MPU-401 (or UART in combination with SoftMPU) port?

And this will be a software emulation, using MUNT on RPi? If so: that would bring a lot of flexibility, given the ability to change the software, upgrade the software, etc.

I looked at this project a while ago. Ultimately, I wanted to connect peripherals via USB rather than I2C or SPI so I could avoid having to make and maintain a custom BSP overlay.

Damn, I had a similar idea in the back of my mind for a while. Googling "buildroot + munt" brought me here. I wanted to use the GPIO for MIDI IN and a 20x1 LCD display, along with a single volume button to replicate the look of an original MT-32 at a much smaller scale.

Obviously you have given much more thoughts about it than I have, so I'll take a step back and follow this thread now :)

this looks cool, how do we understand this: you put a waveboard on a soundcard that has a cable going out to another board ? I don't really get it

Get Raspi as Compute Unit, and place it on a ISA Card with MPU Interface, interfacing to RX/TX Pins of Computeboard.
