A Low Frequency Oscillator. It is similar to a normal oscillator except that it outputs very low frequencies (very slow waves) and is used as a control input into another part of the synth. Examples of its use are to create vibrato or tremolo effects....
Cs-10
The CS-10 is a wonderful synthesizer. The original sound is warm and nice. It's very easy to
use, you have every parameter 'hands on' with knobs (22, excuding volume) and switches (8).
You could acctually see the sound travels at the panel of the CS-10 :-) It has CV/Gate
connections (Key volt in&out, Trigger in&out). Note that this (as the other CS's from Yamaha
and old Korg's) uses Hz/Volt triggering. And a very useful external in, that you could use to
patch all kinds of sounds trough. You also have two sliders for Portamento and Pitch Bend.
These two are not in use when you have the CS-10 controlled via CV/Gate. The Pitch Bend
slides one octave. The VCF has three modes. High, Band and Low-pas
