Sine Wave into Buffer~
The cycle~ object allows you to read from a stored cosine function (use a phase offset of 0.75 to get a sine phase), and does high-quality interpolation to give you excellent resolution even though it only uses a 512-sample table. (See MSP Tutorial chapters 1-3).
But if you want to put a sine wave into a buffer~, here’s a way:
Once opened, the patch will set the buffer~ ‘size’ to the appropriate duration (in ms), at the current sample rate, for 512 samples, using the sampstoms~. Then it will send this same integer (the number of samples) to an uzi, which, in turn, will drive the output of the expr object that will calculate the appropriate value for each sample, and save it into the buffer~.
