How does one go about writing a virtual MIDI interface?

Question

I want to do some funky things with controlling MIDI streams, and I'd like to be able to pipe MIDI input into an application like Ableton or Reason. Presumably this involves some sort of driver level work?

Ultimately I'd like to write my application in Python, so if there is some Python-based solution, I'd consider it. I'm perfectly fine with using C/C++, though, so that's not a problem.

Answer 1

I suggest you check out Audacity http://audacity.sourceforge.net/ it's a gui client but it's also open source so you can probably make(rip out) of it what you need and want.

You can get the source there under /download/beta_source

Answer 2

I'm not sure you need a driver. I think you want to check out VST's, which is a standard for plugins which can be loaded by various DAW's (Digital Audio Workstations).
