I'm working on a plug-in for remapping MIDI notes and I wanted to start off with a very simple test plug-in to see if Camomile will work for my application. I created a simple Pd patch that takes notein, displays the values in number boxes then adds note and velocity (mod 128) and feeds that new note value into noteout. So this should play different notes depending on how hard I press the same key on a MIDI keyboard. I'm testing this plugin in Ardour on Mac and it is not working.

The example AlmondOrgan works fine, but if I insert this test plugin I made, it doesn't display the incoming MIDI values, and doesn't have any effect on the MIDI information flowing through. Any suggestions?
