Warning: loud! It sounds nothing like Church. Tracks are hard synced oscillators where the master stays consistent, and the slave increases a lot. Generated in Csound. The emitters travel up and down the canvas and make a racket of overtones and harmonics. Modwheel is assigned to the filter set to 12db high-pass mode. It really (!!) accents those overtones. Play a chord and sweep that modwheel and prepare for bleeding eardrums.

These samples were uploaded by Andre previously as "synced". That version is definitely less extreme. No high pass filter, and fewer emitter placements.
