FM Modulator Phase


Macro: FMmodPhase

Controls the phase of the Sine modulator, independent of the main wave (carrier) Phase. This is particularly useful if you have set FM Sync, and want to adjust the display sync relative to the modulator cycle.


Macro Notes:

L.1.FMmodPhase=90 sets Left Stream 1 FM Modulator Phase to 90 degrees. Alternatively, FMmodPhase=>1 increments or FMmodPhase=>-1 decrements the current Modulator Phase by 1 degree. Only +/-1 degree steps are allowed with this command format.
