Using the Low Frequency Oscillator on an Analog Synthesizer

Video Transcript

"My name is Dan Rapport. Today we are going to be talking about analog synthesizers. Here we have the modulation busses and the low frequency oscillator or LFO. In the original mini Moog you have to use oscillator three as an LFO, but in the new one they have made it so that you can have an LFO separate. So this modulation bus here these control the modulation wheel that we saw it earlier, and right now I have it set to a sine wave, the rate of which is being controlled by the LFO. The destination is going to the filter, which we talked about earlier the filter cutoff and the shaping of it comes from the envelope generators, the filter envelope generators and these particular modulation busses will allow you to route what the mod wheel does. So here is an example of the sine wave LFO. And I will control the rate to go to very fast to very slow, here the rate is very, very slow. On the other modulation bus is the pedal control which you cannot see, but it is a good example of the square wave LFO as opposed to the sine wave LFO and here is an example of that, you can see it is much more choppier than the sine wave, that is square wave and sine wave, one more feature that we can talk about is the glide rate, which is a pretty interesting feature used on a lot of synths, it allows you to bend or melt the notes in together; a portmanteau control if you will. Here is with it completely off, and now here it is turned up."
