Austen Satterlee has released a free VST plugin for Windows that lets you transform and reroute incoming MIDI signals.

After placing MIDI-Transformer in your VST chain, the plugin will read incoming MIDI values from the selected input source during playback and transform those values using the specified transformation curve. It outputs the transformed values according to the selected output destination.

For example, if the input source was set to CC2 and the output source was set to CC3, the plugin would read all incoming CC2 values, transform them, and then output the transformed values as CC3 messages.

The plugin’s GUI will show a vertical line along the curve to indicate the last input value that was captured, and how it was transformed.

MIDI-Transformer is free to download as a VST3 plugin for Windows at KVR Audio.
