Macro: Offset

Offset here means 'level shift', not the opposite of 'onset'.

The Offset control adds or subtracts a constant value from the stream wave, effectively sliding it up or down within its range. The total of Offset and Level must ordinarily not exceed 100%, assuming a normal waveform that uses all of its range. If you add or subtract too much, the wave slides up or down so far that it is "clipped" to the maximum or minimum value. This produces distortion, which gets worse as more of the wave is clipped off.

Note that sound cards block constant (DC) values from ever reaching the output, so unless clipping is present there will be no audible effect. So, why bother to have this control at all?

The Offset control is useful when the Stream is used as the modulation source for another Stream, allowing you to provide some constant amount of modulation on top of whatever is provided by the simple waveform. You can also use Offset when you are adding Burst or Pulse Streams together. You may not need it often, but remember that it is available... when you need it, it will usually be obvious.

Macro Notes:

L.3.Offset=50 directly sets Left Stream 3 Offset to 50%. L.3.Offset=-50 sets -50%. Alternatively, L.3.Offset=>1 increments and L.3.Offset=>-1 decrements the current Offset by 1%. Only steps of +/- 1% are allowed with this format.
