Main Tone Phase
This sets the starting phase of the main Wave stream, in hundredths of a degree from 0 to 360. The actual output resolution is one part in 8192 per 360 degrees, or about 0.044 degree. If you enter a negative value, it will be converted to the equivalent positive value (-90 = 270, etc).
In Burst mode, without Reset Tone Phase On Burst or Reset Phase On Train selected, this is the phase at the beginning of the entire Burst interval, including any Lag delay. In other words, Lag does not delay the start of the main wave, it just delays the beginning of the burst.
The phase control is useful for starting the display at a certain part of the main wave, and also for adjusting the relative phases when two or more streams are used together.
One non-obvious use for Phase is to produce a constant DC level by setting the main Tone Frequency to 0. Then if you set Phase to 90 degrees, the output of that stream will be a constant 100%. Although this by itself would produce no sound from the AC-coupled outputs of the sound card, it can be modulated by the Burst or Phase Modulation options and used to modulate another stream.
L.1.TonePhase=90 sets the Left Stream 1 Tone Phase to 90 degrees.
L.1.TonePhase=>1 increments the Phase by 1 degree, and L.1.TonePhase=>-1 decrements by one degree. Only +/-1 step is accepted.
