Got an expression pedal working with Jesusonic, yummy (right now it's just
connected to my microcontroller dev board). Since that works, I started 
working on a wah effect. Using a resonant bandpass, seems to be working 
but haven't gotten it to sound decent yet. Here are a couple mp3s.

The first one also has the new advanced drum sequencer I made earlier today,
it lets you specify volume, panning, and additional timing information for
each event. Yay for more flexibility, and it's backwards compatible too.

(One final post-posting note, I realized that picture is giant line6 ad. 
oh well.)
