[chuck-users] small note on LiSa.feedback()

Dear Dan, readme_LiSa2.ck lists; // mylisa.feedback(float); set feedback amount [0,1] for recording As far as I can tell it takes numbers larger than this as well as negative ones; -------8<-------------- LiSa l => dac; -5.0 => l.feedback; <<>>; -------------8<-------------- Amounts with a magnitude of over 1 may be unpractical/dangerous but since we will potentially be dealing with a especially perverted (and interesting!) form of Karplus Strong here I feel the option to use negative number here is rather relevant. Yours, Kas.
