VirtualMIDISynth is a software MIDI synthesizer implemented as a Windows multimedia user driver, accessible as a standard MIDI Out device.

It works on Windows XP (SP3) / Vista (SP1) / 7 (SP1) / 8.x / 10 (both x86 and x64), and is based on the great BASS library from un4seen.

Main features

  • User mode multimedia driver, no reboots, no BSOD
  • Directly accessible as MIDI Out device, no need for virtual MIDI cables (like MIDI Yoke, LoopBe1)
  • Supports up to 4 virtual devices, each with its own soundfont configuration (new in version 2.x)
  • Virtually unlimited polyphony (limited only by available CPU power)
  • MIDI mixer to set track mute/volume, accessible through systray icon
  • Integrated MIDI converter to easily convert your MIDI files to WAV/MP3/FLAC
  • Lightweight setup (~1.2 MBytes)
  • No DLL cluttering, everything is self contained installation folder (except for MIDI device driver) (new in version 2.x)
  • Clean installer, won't affect other MIDI devices
  • Efficient RAM usage (allows using large SoundFonts, > 1GByte)
  • Load soundFonts (up to available memory), enable/disable/chain them at your will; native 64bit version (on x64 OS) is not limited to 4GByte (new in version 2.x)
  • Configure MIDI Mapper default device (this feature is already available in XP, but missing in Vista / Windows 7)
  • Windows 8/10 users can also install CoolSoft MIDIMapper and configure it straight from VirtualMIDISynth configurator to get the well-known MIDI Mapper back to their systems
  • Multilanguage dialogs.
