Creating sounds
By using an LFO (Low Frequency Oscillator) waveform to control the OSC 1/2 PITCH, the FILTER CUTOFF, or
the AMP LEVEL, you can apply cyclic change (modulation) to the pitch, brightness, or volume.
The SH-201 has two LFOs; LFO 1 and LFO 2.
You can use one LFO to control up to two destinations (DESTINATION 1 and DESTINATION 2, p. 42 and p. 43)
such as pitch or volume.
fig.LFO-buttons
Use these buttons to specify whether you’re making settings for LFO 1 or LFO 2.
Press the button for the desired LFO; it will light.
fig.SHAPE-buttons
Use these buttons to select the LFO waveform. One of the indicators will light to indicate the waveform that’s
selected. Press the right button to move clockwise through the selections, or the left button to move
counterclockwise.
