Re: [sc-dev] Valid UGen input rates
Most don't... most input rates take audio or control (but may only read them as control rates). IF they ONLY want audio rates (like Pan2 for instance), then inputs are checked. Otherwise, you need to check the source.
Perhaps a classvar for UGen would make sense?
classvar rates;
then - a symbol to describe value inputs?

I think Scott (?) started to do that some time ago? We really all should pitch in and get that done. With CSound - they name the arguments according to acceptable rates, but an array after the arg description in the doc is probably what we need (and I think it is what Scott started to do?).
