Re: using the UM-One
The Pi 2 supports using the integrated UART on the GPIO header for MIDI in/out. One must then build the isolation/current loop circuit, but this is the same as building a sound card MIDI adapter and is very well documented.

The Orange Pi may support a similar method, but I haven't looked to see if the Orange Pi is compatible with the kernel module in question.

The OPi actually has a dedicated header for UART, that is normally used for a serial console but is easily repurposed for anything else (the Odroid C2 has a similar dedicated UART header).

Now if there's just a way to have a toggle switch to select either SC-55 or MT-32 😀

That's the plan! All the toggle has to do is disconnect the midi in from Munt and connect it to Fluidsynth/Timidity (and vice versa). I'll also push a message to my LCD.

The work being done on Pi and other mini computers is terrific, but I'm wondering if anyone has the skill, time and passion to write a front-end or something like that for Windows to use on a standard notebook with MIDI interface?

Are you wondering about a scripted setup?

As long as the UART supports a MIDI compatible clock, I suspect ttymidi can be made to work.

Yea, basically what you're working on, but for Windows and a simple application.

The Pi 2 does support Windows (sort of), but it's certainly no easier to do this on than Raspbian.

Once I'm done, I hope the software end will be no harder than writing an SD card then copying the MT-32 and CM-32L ROM files. General use will be via a few buttons on the front for mode, reset, etc. I think that's pretty easy.

This is awesome - Thank you!

In preparation.. Could somebody point me to the cable I need? I plan on using a SoundBlaster 16 CT1750. I want to route that to USB for Munt and SC-55 emulation.

You'll likely want one with a joystick pass through.

Check the first post. I've outlined all the parts needed 😀

I'm not sure how I missed that first post. I have too many Vogons tabs open at once 🤣

Let me know how you go!

I'd love an interface for Windows. Even if it's just some batch files, that would make it much more user friendly.

Long time lurker - finally this project convinced me to register 😀

Has anyone actually confirmed that this fix makes this kind of cable work with Munt? I suppose it should since it seems to make the USB Midi cable work with MIDI-OX and I remember reading in another thread that Phil was having problems getting it to recognise anything. If it works, I'm going to purchase everything soon and start this thing right away 🤣

Thanks!

I would wager money that the chip on board semiconductor under the epoxy blob is a bog standard UART which has been clocked appropriately for MIDI. The remaining features will be for isolation and current loop conversion. If this isn't done properly with buffering and optical isolation, the adapter will be sensitive to source and load impedances. Removing these parts will result in an adapter that will work, sort-of, sometimes.

So, I haven't confirmed the fix (although the referenced web site did), but the situation and remediation does make sense both in terms of engineering and dodgy business practices.

I wonder if a WinBook Tablet with Micro USB adapter (for MIDI adapter) would run Munt and Sound Canvas VA. Does anyone have one of these? They go for cheap and have actual Windows installed - not RT.

Specs?

I'm actually considering this unit now
http://en.chuwi.com/product/items/Chuwi-Hi8-pro.html

I just want something smaller than a laptop that can run Munt and Sound Canvas VA - sit in a little stand on top my retro PC and cost under $100

Can use it for other purposes also. This unit dual boots Android - interesting

Still looking forward to the pi stuff of course

Fellows I just installed MUNT for the first time and found SCC1 utility with midi files that set the SCC-1 or SC-55 to MT-32 mode and back.
I found about SCC-1 soundfont and CoolSoft VirtualMidiSynth late last year.
Along with SC-VA, I'm having major fun and rediscovering what I missed in the 90's, back then I only had a Sound Blaster Pro with OPL3.
It's only in the last year I have found that the games I played as a kid did not sound their best but it's how they are most nostalgic to me, pure OPL3 (FM Synth) on everything.

Now that we have everything emulated to perfection (SC-VA from Roland, and actual MT32 & SCC1 Roms), for the late fellows like me who didn't want to invest in hardware.
What's next?

I just ordered my Roland UM-ONE - about the only Roland hardware I can afford 🤣

What's the best free alternative to Sound Canvas VA?

Is Munt still the best for MT-32?

For Windows, probably BassMIDI. Fluidsynth for Linux. You can experiment with soundfonts to see which sounds best or more true to you.

Munt is really the only MT32 / CM32L emulator, though.

I finally got all my parts and everything setup with a laptop. But I'm not getting any sound.

AWE64 > MIDI OUT > coupler < MIDI IN Roland UM-ONE MK2
SOFTMPU.EXE /SB:220 /IRQ:5 /MPU:330

SAVIHost renamed to "SOUND Canvas VA.exe" on laptop
Devices / MIDI / Input Port 1: UM-ONE

Set Doom to Sound Canvas

Nothing 🙁

Installed Munt, Soundfonts, Set device to UM-ONE
Tried Sierra's Codename: Iceman but I just get a black screen (was just a long delay from SoftMPU)
But unfortunately no sound still.

The UM-One MKII has the labels telling you what to connect it to. Swap in with out 😀

So MIDI out of the Sound Blaster goes into MIDI out labelled plug on the UM-One MKII.

The UM-One should MIDI flash when receiving input.
