Hey all, Long time listener, first time caller. I'm a little bit new to this, but I managed to write a program that uses LiSa to play a sample of a piano harmonic at a specified rate, putting it at a specified partial. Here's the deal: I want to just do chuck harmonic.ck:4 for the 4th partial, or chuck harmonic.ck:5 for the 5th, but it keeps telling me that my arguments are strings, not floats. Is there a way to do a string-float conversion, or just even to read a particular argument as a float? float harm; string arg1; me.arg(0) => arg1; ... arg1 => harm; is all I have relating to the arguments. Obviously, that doesn't work, as you can't ChucK a string to a float. There's probably a simple answer to this, isn't there? Andrew Smith
