A pack of MIDI utility plugins I made to use with Tracktion's Rack Filters (though they'll probably work in most hosts). Uses the Simple Controls library of widgets I'm making for VSTGUI (still in development, not sure I can really be bothered to finish them)

MIDI Note Filter : Allows through only the selected note.

MIDI Note Trans : Transposes all incoming note values by the specified amount (irrespective of key).

MIDI Channel Filter: Only allows through MIDI messages from the specified channel. Useful for doing global transpositions (see readme).

MIDI Velocity Amp : Amplifies/attenuates incoming velocity signals.

MIDI Channeliser: Forces all incoming signals to the specified channel.

MIDI Force2Key: Forces all incoming notes to a key specified by the user. Also allows for transposition within the key.

MIDI Note Range Filter: Only lets through the specified range of notes.

MIDI CC Range Filter: Only lets through the specified range of cc values.

MIDI Velocity Range Filter: Only lets through the specified range of Velocity values.
