ratio at a low operator level with even-ratio operators to add bite to a string sound
and many other effects.
The standard DX27 keyboard pitch is 8’; therefore, in terms of footage: 0.50 = 16’,
1.00 = 8’, and 2.00 = 4’.
14: DETUNE
This parameter permits slight detuning of the selected operator in relation to the
others, making it possible to create richer, fuller voice effects. If detune is applied
to carriers, the result is a thick, multi-instrument effect. Applied to modulators, the
result is a slight periodic variation in timbre similar to a phase shift effect.
The data range is from -3 to +3, for a maximum detuning range of +2.6 cents.
At 0, no detune effect is produced.
15-19: ENVELOPE GENERATOR, AR, D1R, D1L, D2R, RR
These buttons select the specific envelope generator parameters to be worked on:
ATTACK RATE, DECAY 1 RATE, DECAY 1 LEVEL, DECAY 2 RATE, and RELEASE
RATE.
The data range for AR, D1R, AND D2R parameters is 0 to 31, with 31 being the
fastest rate (Instantaneous) and 0 the slowest (i.e. no change). The RR parameter
has a data range of from 0 to 15, with 15 being fastest release and 0 being the
slowest.
The following EG curve shows the relationship between the RATE and LEVEL
parameters.
