I am looking for a small MIDI synthesizer for Windows. It must accept MIDI notes from MIDI ports. On Mac I've found this


which works nicely. Anything for Windows?

Note: I'm looking for something free and compact, so how it sounds is not important in this context.


Try CoolSoft's VirtualMidiSynth.


While I don't know of a freeware all-in-one synth for Windows, you could roll one yourself by using Tobybear's MiniHost together with a free VST plugin, such as Oatmeal.

It's been awhile since I used MiniHost, but I recall that it can interface with the system MIDI ports, and that you can also instruct it to automatically reload the last plugin on startup. This way, you get a standalone synth without the hassle of a sequencer.

  • Thanks Nik, really to avoid more work here. I'm creating an iPad app that talks to a Java app. I just want to synth to be able to demonstrate how the thing works. Are there any free DAWs that come with synths for Windows? – Dan Rosenstark Oct 19 '10 at 19:21
  • @Yar, not sure about any that come with synths, but reaper.fm is at least free for windows. But like I said, there's a ton of great, free VST synths out there... it's really not so much work as you think. – Nik Reiman Oct 19 '10 at 19:42
