This video covers the basics of Frames and demonstrates a handful of uses for the module:

1:4 mult
Attenuating mult
4 channel attenuator
4 channel mixer
Crossfader
Panner
Sequencer
Envelope

One quick note about the envelope that I forgot to mention in the video, it could actually be trigged by a single gate, given that you have a module to slew a square wave. Then it would act as a sawtooth, playing the envelope sequence forward like I show at the end of the video.
