Hi Ethan,
Thanks for asking. We are still working on a multi-rate version of Faust,
even if its development is not necessarily going as fast as we would like!
The idea is to introduce the multi-rate aspects as a new class of
primitives focusing on the signal processors themselves (rather than
operations on the signals). These new primitives allow controlling the time
base with which signal processors work.
Take a signal processor P with n inputs and m outputs, then ondemand(P) is
a new signal processor with n+1 inputs and always m outputs. The additional
input is a clock signal that controls when the computations are done.
Similarly, upsampling(P) and downsampling(P) add an input to control the
time base by a multiplying or dividing factor.
Upsampling and downsampling are essentially variants of ondemand. A
preliminary specification of ondemand is available here:

Cheers
Yann
