BassMIDI VSTi is a portable VST 2.4 instrument/software MIDI synthesizer for Windows that is based on the Bass/BassMIDI libraries by Un4Seen.
You need some SF2/SFZ soundfont (s) and a VST Host/DAW to use it. In the package both x86 and x64 versions are included for different x86/x64 hosts.
Using x86/x64 host bridges are not recommended.
Bass.dll and Bassmidi.dll have to be copied to the same (VST) directory as BassMidiVsti.dll.
Copying BassMidiVsti.vstxml is optional. It's only included for easier parameter customization.

Bassflac.dll is also optional, it's only needed when FLAC compressed SFZ files are used.
Supported MIDI events/controllers can be found in
BassMIDI documentation.


  • Fast and lightweight.
  • Supports both 32 and 64-bit processing.
  • Supports up to 5 different stacked soundfonts even on different banks (16384 maximum instruments).
  • Supports 12 different Reverb/Chorus effect types.
  • Supports 14 parameters for options that are not (or not easily) MIDI controllable.
  • Can send MIDIProgramNames to hosts that support it.

version 1.2

Fixed restoring MIDI channel related settings (program, bank, modulation etc.).
Fixed some UI related problems.
Added new bassflac.dll version to handle loop information in FLAC files.
Added new bassmidi.dll version to handle SFZ program names.

So happy this exists, finally a VSTi that faithfully plays soundfonts, was almost tempted to make something like this myself, since everything else out there is either outdated, unsupported, broken or fake.

I've seen bass.dll present in numerous games' folders. I'm trying to wrap my head around this VST — what's it for, how it could be useful? Is it different from an SF2/SFZ player in terms of features or structure?

Hi, .

Do you remember Cakewalk/rgc:audio SFZ? It's something like that but tries to correct some of its issues:

1. It cannot run reliable on systems with more than 2GB of RAM.

2. It can only load 1 SF2/SFZ file at once.

3. It uses a buggy XG/GM2 addressing mode that is weird since Sondfonts are inherently more GS like.

4. It's does not follow the SF2 specification. Bassmidi library is much more reliable in this respect, ans it's still constantly evolving.

But the most important one: there is a need for it :)
