MSP More about cycle~

Previously we defined cycle~ as a sine wae oscillator generator. It is actually capable of doing a lot more.Computers generally generate waves (sine waves for example) by looking at stored tables and readingthrough them at very fast rates. For example, to produce a sine wave of A440, the computer may readthrough the wave table 440 times per second.

Cycle~ is no different. It is also a wave table look up. By default it has 512 values in the table, in the shape of a sine wave. 512 samples equals 11.61 ms buffer length.

a buffer length of 11.61 ms is equivalent to 512 samples

cycle~ heythere

buffer~ heythere 11.61440.

With peek~ we can get different wave forms into buffer~ so that cycle~ can generate a different kind of waveform, even one that you draw.

edit table. Get info (size - 511)

numbers 1 - 512 sent out as fast as possible

place into a range of 0 - 511

limit to a range of -1. to 1.
