;; As for your question about the snare synthdef, pulse-divider doesn't actually generate any triggers on its own, it just outputs a trigger every div triggers. So instead you could try something like this:

(in-package #:cl-collider)

(defsynth snare ()

(out.ar 0 (white-noise.ar (decay2.ar (pulse-divider.ar (impulse.ar 4) 4 2) 0.005 0.5))))

(out.ar 0 (white-noise.ar (decay2.ar (pulse-divider.ar (impulse.ar 8) 4 2) 0.005 0.5))))
