Yes, you can tempo sync parameters using Csound externals with either PD or
Max/ Max for Live. To leave an instrument running for a performance, you
would typically use the turnon opcode on the instrument processing your
sound, and load an empty ftable a long time after the performance starts
(the performance will not stop until the ftable is loaded, which allows you
to use pass realtime audio through an orchestra for extended periods of
time). You can also send an instrument message with a long duration to the
instrument that does your audio processing. I tend to make all of my UI in
Max, and do all of the audio processing in Csound, using the csound~
external. I think doing something like a multifx pedal is easier to program
and more efficient in Csound than in Max or PD. If you're interested in
using the Csound code inside of a DAW other than Live, then I would look
into Cabbage (although, I don't think there is currently AU support).

Just glancing at the examples you gave, I don't see why you wouldn't be
able to make any of them in Csound.
