Munt comes in two flavors:
1. A Windows MIDI driver, downloadable from the sourceforge project site.
- Can be used with any program that is able to use Windows MIDI drivers.
- This version is probably your best option for the most up-to-date Munt version, unless you are a developer.
- Latest version has a GUI that asks you where your ROMs are, and which ones to use (e.g. MT-32 versus CM-32).
- Allows you to see MT-32 emulation status (including a simulated LCD) and alter some settings via a GUI.
- May be harder to get working in Windows Vista and newer, as you will either need to configure each program to use it, or use a third-party utility to change the default Windows MIDI driver selection.
2. A library.
- (developers only) Can be built into programs to provide built-in MT-32 emulation support.
- Generally easy to configure the application to use it (via configuration GUI or configuration file).
- A copy of the ROMs must generally reside in the same folder (or a subfolder) of each program that uses them.
- The programs that use the library may not provide access to a GUI for monitoring or configuring MT-32 emulation status.
I've been doing #1 lately because projects using #2 don't generally pull the latest library source into their projects as often as the Munt team has been releasing driver updates.
If you want to do #2 for DOSBox anyways, I would suggest Ykhwong's excellent "DOSBox Daum Cafe" enhanced SVN build of DOSBox. He patches in the library flavor of Munt.
