Setting the OSC 2 - 3 FM Envelope Amount
Many sounds have complex harmonic movements at the start
of the sound. Introducing envelope modulation from an enve-
lope with a fast attack and decay time to control the FM amount
will simulate this fast changing harmonic effect.
Once in the Oscillator Menu (see previous page), a further key
press will enter the OSC 2 - 3 Envelope Amount settings. The
display will show F E and an alternating value. Adjust this value
using the PORTA/DATA knob. Notice how the ‘spit’ at the begin-
ning of the sound may be accentuated. Experiment with
Oscillator 2 pitch using the OCTAVE switch, SEMITONE and
DETUNE knobs.
Adjusting the FM Envelope Attack and Decay times
Assuming the the Oscillator Menu is selected and FM Envelope
Amount was the last selected item, a further key press will
enter the FM envelope attack time options. The display will
show F A and an alternating value. Adjust this value using the
PORTA/DATA knob.
A further press will select the FM envelope decay time options.
The display will show F d and an alternating value. Adjust this
value using the PORTA/DATA knob.
