Here we are at the close of our series on creating a guitar processor in MSP. To wrap things up, I want to make a connection to the real world - to hardware. In previous iterations of this series, we created a complicated pattr-based preset system, then coupled it with an equally complex routing system. When using the system, I found that what I really wanted was hands-off preset selection, and simple volume control from a foot pedal. So we’re ending this series by adding a simple - but effective - MIDI pedal connection.
