![]() ![]() Once you can put two and two together, you'll be able to look at an LFO wave and tell how its going to sound modulating something.Īlso realize that unless you offset them, LFOS are positive AND negative modulation. ![]() Notice how the pitch starts high and then falls, but doesn't gradually rise again? If you have a saw lfo (or use the QPLFO so the Skew is full CCW and the symmetry is centered) do the same thing as before. This is because there is no gradual change in the shape of the square wave, but an immediate jump. You'll notice now that there is no gradual shift in pitch, but an immediate change from a high pitch to a low pitch. Now use a square wave LFO on that same 1v/Oct jack. Hear how the pitch changes smoothly up and down? Thats because the shape of the wave does the same thing. Plug a sine or triangle wave into the 1v/Oct jack on an oscillator and turn the lfo rate down a bit. So think of putting the waveform on a graph like so: If you think of the shape of the waveform as a graphic representation of the amount of modulation over a course of time, it may help more. An LFO is basically an oscillator that is running so slowly that you cannot hear it. ![]()
