Roland MT-32, CM-32L and General MIDI for $50!



Apologies, for the catchy title. I just wanted to grab you attention because I am very excited about this project :). I am showing how to build a MIDI box for your Retro Gaming PC that will substitute Roland MT-32, CM-32L and General MIDI.

Instead of having to buy this:

You can build something like this:

Please note that a space notebook or desktop is required, but it doesn't have to be very fast. I'm using a 1.7 GHz Celeron notebook.

The main ingredient of this MIDI Box is the Roland UM-ONE mk2 USB MIDI adapter, which you have to purchase for around $50. I've tried a cheap one from eBay, but sometimes instruments sound wrong. So here it pays to invest a little bit more. Other branded products should also work, but I have only tested it with the Roland UM-ONE mk2.

The video shows step-by-step instructions of how to build your MIDI Box, and how to set it up for MT-32, CM-32L and General MIDI operation. Recordings of Monkey Island 2, Space Quest III, Ultima Underworld,

Parts needed:

ISA soundcard with MPU401 MIDI interface (UART mode, use SoftMPU for intelligent mode) and line-in
MIDI cable for you soundcard
MIDI joiner if necessary (female on both ends)
Roland UM-ONE mk2 USB MIDI interface
Spare desktop PC or notebook
Audio cable (headphone jack to headphone jack)

Software needed:

BASSMIDI

MIDI-OX

Wow, das ist eine wirklich geniale Lösung.
Das ist die perfekte Aufgabe für mein 11,6" Netbook.
Vielen Dank dafür! :-)

Very Cool, I have to try this out. :-)
I will give the 6€-Adaptor from Amazon a chance before buying the expensive Roland thing.

Dos anybody know where to get those Ganeport to DIN Cables? Couldn't find one for < 20€ :-(

I found this one: http://www.ebay.com.au/itm/MIDI-Organ-E ... 5d59081a0d

Postage might vary from your country.

You will also need a MIDI joiner: http://www.ebay.com.au/itm/Swamp-Audio- ... 1e6cdcebac

Another option is to make your own cable :) The pinout should be easily found online.

Big thx for the nice overview, I will try it :-)

By the way, if the second machine is a desktop, an old soundcard as MPU401-interface also works great (for example cmi8738) :like:

Let us know how you go.

Das schaue ich mir noch mal genauer an. Vielleicht ist das was für mich, wenn dann aber nicht mit einem Laptop oder weiterem vollwertigen PC.
Denke da an den Raspberry.
