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;

<<<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.
