DFX Buffer Override

Buffer Override can overcome your host app's
audio processing buffer size and then (unsuccessfully) override that
new buffer size to be a smaller buffer size. It makes a lot more sense
if you just try it out and hear what it does. It can sound like a
stuttery vocoder or a stuck beat shuffler or many other delightful
things. In certain hosts, you can also "play" Buffer Override via MIDI
notes and even sync it to song tempo.
