yup, another good vid.
i'll add my tuppence, as well
one of the cool things you can do with parallel paths is use fx to effect other fx, but leave your dry signal intact. an example....say you put a delay in parallel at 100% wet. now no dry signal is passing through that effect, so if you put a flanger behind the delay and then join back to the main line, the delay repeats will be flanged, but your dry signal won't. you can set up chains of stuff which you can enable simply by unmuting the first effect in the chain (if the bypass mode is set correctly).
multidelays running into pitch shifters...reverbs running into lfo controlled filters...pitch shifters running into multidelays...i have patches with 7 or 8 effects in a parallel path (which may even have it's own parallel sub-path), to create huge ambient scapes which appear "behind" a simple unaffected clean sound (which i can bring in or out as i wish). it's a very powerful technique!
