New MIDI Filter - Controller Latch

Here's another little improvement inspired by a question on the forum.

The question was asking how to use a MIDI button or pedal to toggle the leslie speed of a B4 from fast to slow. Although Cantabile supports assigning CC's to VST parameters, it's a direct mapping from CC value to VST parameter value. What this means is the leslie would got to fast when the pedal is pressed and slow when the pedal released.

What's needed is a way to convert a button or pedal press into discrete CC values. In other words, a way for each press of the pedal to generate and alternate CC value. Time for a new MIDI filter... Controller Latch.

The controller latch MIDI filter is a simple filter that looks for incoming button presses and generates a sequence of outgoing CC values for each press. It's not limited to a simple toggle either - you can define as many CC values as you like and they'll all be sequenced through.

This will be in the next official build, or you can grab an interim experimental build here:
