3. To select another parameter of the current oscillator, press either Wave#,
Coarse Freq, or Fine Freq.
4. To select another oscillator, press Oscillator Select until the desired oscillator
(A-D) appears in the top display line, then repeat the last two steps.
Stepping through the oscillators with Oscillator Select does not alter the
position of the display cursor. This method of adjusting oscillator parameters
allows you to quickly modify program settings either one oscillator at time
(by switching between parameters), or one parameter at a time (by switching
between oscillators).
Descriptions of each oscillator parameter follow.
Wave #
Each oscillator may generate a dierent waveform. When Wave# is selected,
the slider adjusts the wave number assigned to the current oscillator. There are
127 waveforms available. Waveforms are organized as follows:
0-31 User waves (RAM)
32-127 ROM waves
#32 Sine wave
#126 Null wave (silence)
#127 White noise
The musical value of specic waveforms can only be learned through trial
and error, working with various program settings (“patches”). Although some
simple waveforms are included, the ROM waveforms are much more complex
than the typical sawtooth and pulse waves on an analog synthesizer, and
therefore they do not lend themselves to generalizations such as “sounds
brassy”, or “contains only odd harmonics.” Since they were created and are
edited by ear, there is no point attempting to discuss the specic harmonic
content of the ROM waveforms.
Coarse Freq and Fine Freq
Each oscillator’s tuning is displayed as a four-digit number. The rst two digits
represent the Coarse Frequency (number of semitones above concert pitch),
which is adjusted by pressing Coarse Freq, then adjusting the slider. For
basic “concert” tuning, set Coarse Freq to 0. For that oscillator, middle C will
then be located at key C3. Values 12 and 2k are one and two octaves above,
respectively.
The second two digits represent the oscillator detuning in cents (hundredths
of semitone), which is adjusted by pressing Fine Freq, then adjusting the
slider. Fine Freq is often left set to zero, so that the oscillator is not detuned.
However, detuning is actually a great resource for making timbres sound less
pure and machine-like.
