Different Kinds of Reverb
If you're looking for inspiration on different kinds of reverb to implement later on, may I suggest checking out the algorithms that Tom Erbe used in the Erve-Verb by make noise. As far as I understand they are all based on simple delay taps and filters that feedback into themselves, so I imagine they would be light on processor power. He made some Max/MSP and PD versions of the patches and they sound amazing.
And, while probably processor heavy, implementing some kind of convolution reverb would be wild. Have a folder where you store impulse responses or use samples recorded directly with the Deluge as impulse response. That would be fun! Ha!
