• Wave Select / PW
The function of the WAVE SELECT/ PW knob varies depending on the Oscillator Mode and the current value
of SHAPE. Starting with patch ROM B-120 'Tutorial 1', please take some time to explore the different modes
and how the WAVE SELECT/PW knob behaves in each (first ensure that SELECT is focussed to OSC1):

• Semitone
Adjusts the base pitch of the selected oscillator in semitones. You can pitch each oscillator by +/- 4 octaves.
Use steps of +/- 12 semitones to adjust the pitch by an octave.
**Please select patch ROM B-121 'Tutorial 2' before continuing.**
• Detune 2/3
Use the DETUNE knob to create a slight offset in the pitch of either Osc 2 or 3. Suitable amounts of detun-
ing between the oscillators can really help to make a sound 'warmer'. If OSC SELECT is either OSC1 or 2
then the target parameter is always Oscillator 2 Detune.
• FM Amount
FM is an abbreviation of Frequency Modulation, a process by which the frequency (pitch) Oscillator 2 is
modulated by the frequency of Oscillator 1. The resulting effect is often a dramatic distortion of the affected
oscillator, but there are also 'sweet-spots' to be found, where the effect is more subtle and harmonious.
Experiment with different values for Osc1 and 2 Semitone and FM Amount. If you want a purer, less dis-
torted FM sound, use a sine wave for Osc 2 (turn SHAPE fully anti-clockwise).
The function of the FM AMOUNT knob varies depending on the mode of Oscillator 2:

Sweeps through the Index of the current wavetable

If Shape = Wave>Saw 98% or less, the function is Wave Select, which allows you to
choose between Sine (default) and 63 different 'spectral' waves. If Shape = Saw....
Pulse, the function is Pulse Width, which affects the width of the Pulse wave
