;
#X text 139 152 [tabosc4~] is a traditional computer music style wavetable
lookup oscillator using 4-point polynomial interpolation. The table
should have a power of two points plus three "guard points" \, one
at the beginning and two at the end \, which should be wraparound copies
of the last point and the first two points \, respectively. The "sinesum"
and "cosinesum" methods for arrays do this automatically for you if
you just want to specify partial strengths.;
