AMPLITUDE:
Sensitivity to amp I itude modulation is variable from 0 to 3.
Amplitude modulation sensitivity is set independently for
ea ch operator . Applying amplitude modulation to a mod-
ulator creates " w ow" effects , while applied to a carrier it
results in tremolo effect s.
Operators are selected using the
I

LECT! key Pressing the

successively selects the operators in order from 1 to
4. T he number of the se lected operator is disp layed
in the upper right hand co r ner of the display panel.

and the number of the next active operator wi II be

SYNC (Synchronize):
When the SYNC function is ON, all operators begin oscilla-
tion from the same phase angle (0 degrees) With SYNC
OFF the phase angle at which an operator begins oscilla-
tion is carried over smoothly from the preceding note. In
the polyphonic mode, for example, maximum simultaneous
output is 16 notes. If a 17th key is pressed the first note
makes a smooth transition to the 17th note.

The envelope generator determines how the amplitude
(volume) or timbre (tone) of a note wi ll vary over time.
Enve lope modu lation of a modulator results in time-based
tim bre variations, w hile envelope modulation of a carrier
produces amp litude variat ions.
