Midifork

Midifork is software MIDI controller which supports a variety of output options. MF is a tool for sending various sequences, envelope data, and controller messages out any connected MIDI device or directly to other applications. While Midifork 2 was originally designed to be an extension to Spongefork's interface through the IAC bus, its use doesn't end there. By using MIDI events as the protocol for communication, MF is capable of driving any other device or application as well. Midifork is potentially the simplest and most intuitive way to automate MIDI controller information and other professional audio applications on Mac OS X.
