Jason then did some actually useful stuff and showed additional techniques for specifying filter parameters and employing them algorithmically. He also highlighted a few aspects of Max/MSP (like right-to-left precedence) that are Good Things to Know. Here's what he had to say about the class:
Then we looked at filtergraph~ a little more and built a simple patch with 2 bandpass filters whose center frequencies were controlled by x/y mouse position and gains were controlled by x/y velocity. Originally, I was going to let them loose at that point to extend it in various ways (e.g. signal-rate ramps of the parameters with line~, "quantizing" freqs to a scale, or something else fun and exciting), but at that point there were only 10 minutes left in class. So instead of doing the group work, I showed them a similar patch that used a wacom tablet to control it. The point was to start them thinking about interactive control of synthesis that goes beyond moving sliders on the screen, and beyond controlled a single parameter at a time.
