II. FUNCTIONS FOR SOUND CREATION

LFO

The low frequency oscillator (LFO) is the modulation source for the SH-01A. Here you can create cyclic changes to
various destinations on the synthesizer. You can make the filter frequency rise and fall, or create a vibrato like gate, or
even set a pitch that rises and falls. The shape of this modulation can be set to six different settings, and adjust the
amounts with three different attenuators and two different switches. The behavior of the LFO can be addressed in the
system settings where a choice between the classic SH-101 style is default, and an advanced setting can be
selected. See page XX for more details about how to choose this setting.

EXPERIMENT:
1. Select a patch, or adjust the settings on the front panel to create a sound you like.
2. Raise the MOD slider in the VCF section and listen to what happens to the sound.
NOTE - If you don't hear any change, try lowering the FREQ slider until you start
to hear a cyclic change in the sound.
3. Now adjust the LFO RATE slider and see how this changes the way the sound feels.
4. Select a different WAVEFORM shape for the LFO.
5. Do you like this? Does a cyclic change make things start to happen for you? Or
do you prefer a steady sound?
NOTE - You can attenuate the amount of effect the LFO has on any given
destination by lowering the MOD slider from all the way up (very intense) to
almost completely off (very subtle.) Mess around with this.
