set \, the waveform won't be remembered as part of the patch but will
be reinitialized to zero when the patch is reopened.;

#X text 35 395 For efficiency's sake tabosc4~ requires that the table
have a power of two plus three points (64+3=67 \, 128+3=131 \, 256+3=259
\, etc.) If you want wraparound to work smoothly \, you should make
the last three points copies of the first three. This is done because
tabread4~ does 4-point interpolation.;
#X text 38 494 If you want a specific sinusoidal composition \, you
can send table10 a message \, as below (see 11.arrays in the control
examples):;
#X text 36 240 Here \, in place of the "osc~" cosine wave oscillator
\, we introduce the tabosc4~ oscillator which produces an arbitrary
waveform. You can draw in the waveform with the mouse.;
