ΦM Dev Couple Off On
This softkey toggles the ΦM deviation coupling on and off. Turning on ΦM
deviation coupling links the
ΦM deviation values of ΦMPath1 and ΦMPath2.
When the values are coupled, any change you make to one
ΦM deviation value is
applied to both
ΦM deviation values.

Φ
M Dual-Sine Ampl Ratio
Press this softkey to set the ratio of the deviation of ΦM tone 2 to the deviation of
ΦM tone 1 as a percent. The range of values allowed is 0 to 100%. The minimum
increment allowed is 0.1%. The sum of the two
ΦM deviations results in the total
ΦM deviation (set by the ΦMDev softkey in the initial ΦM Menu).
For example, if the total
ΦM deviation is 300 radians and you set
ΦM Dual-Sine Ampl Ratio to 50%, then the deviation of ΦM tone 1 will be
200 radians and the deviation of
ΦM tone 2 will be 100 radians (50% of
200 radians) so that the deviation of the two tones adds up to 300 radians
(200 radians plus 100 radians).
