Munt MT-32 emulator VSTi is a portable VST 2.4 instrument/software MIDI synthesizer for Windows that is based on Munt.
It is primarily developed for my Soundfont MIDI Player to integrate MT-32 support but apart from this it is a full fledged VSTi plugin.
You need the MT-32/CM-64 Control and PCM ROM images to use it. Unfortunately it is not legally allowed to redistribute these files.
But if you do not have the proper ROM files you can try these images.
In the package both x86 and x64 versions are included for different x86/x64 hosts.
Using x86/x64 host bridges are not recommended.
Mt32emu4v.dll has to be copied to the same (VST) directory as MuntVsti.dll.
Supported MIDI events/controllers can be found in Roland's documentation.
Contrary to normal Munt releases x86 version of MuntVsti works even on Win9x.
Notice:
Since Munt only supports 32000, 48000, and 96000 Hz, you have to set one of these sample rates in the host.
These frequencies correspond the COARSE, ACCURATE, OVERSAMPLED analog output modes in Munt.
Since Munt also uses 32kHz internally for timestamps in order to get the most accurate timings 32kHz is recommended. But 96kHz is still preferred to 48kHz.
From version 2.0 the plugin supports any sample rates through internal resampling but the above written about timings still holds.
Features:
version 3.0
1. Added newest Munt core library version 2.8.0
2. Implemented infrastructure to work with the new MT32 Patch Editor:
https://github.com/MusicallyInspired/MT32edit4v
3. Due to the new infrastructure the 2nd synth instance is now a full synth with all 9 parts available.
4. Some other minor fixes and optimizations.
Too bad there is no way to edit patches. A VST version should have included a panel for patch editing while this is entirely program and sysex driven, pretty just a VST wrapper of munt.
Edit: I contacted the author to discuss this, but he manifested no interest, despite it could have been the first programmable LA32 VST synth around. A real pity, but since it is free one can't insist.
EDIT: now (may 2026) thanks to my request, a volounteer made an editor dll which integrates transparently in Munt VST. I tried it and it does its job very well ! Now I can say we finally have a true LA32 VST synth, and is free ! Ok it may not be very CPU efficient because it is based on munt (any coder looking at the sources can say how inefficiently it was coded) but it definitely does its job !!! Now nostalgic musicians who want to recreate their old Roland D-10/20/110 or MT 32 sounds in a modern environment have a finally a solution. Requires Roland ROMs though, but they can be easy found online (I wonder, to which point Roland still bothers for ROMs used in instruments of the 80s/90s ??? Meh...

What a wonderful project! Mt32 which sounds much better than D110 thanks to 32-bit floating point internal rendering! If I only have editor for those sounds build in...
From version 3.0 you can have an editor in the form of an optional/additional editor plugin:
