I have been using sinesum to create square waveforms in arrays to be read by [tabosc4~] but I am not sure about the amplitude of the partials. I have been reducing the amplitude by half and the waveform doesn't look square enough to me. Am I doing this properly?

[$1-osc sinesum 64 1 0 0.5 0 0.25 0 0.125 0 0.0625 0 0.03125; |
[$1-osc normalize 1

It's
cosinesum 64 0 1 0 -0.333 0 0.2 0 -0.1428 0 0.1111 0 -0.09090
or
sinesum 64 1 0 0.333 0 0.2 0 0.1428 0 0.1111 0 0.09090
