Distortion and Lofi effects are audio processes that alter the relative quality of sounds. This can be by the addition of harmonics, reshaping of waveforms, reduction of sample rate and reduction of bit depth. They will do this by emulating various physical processes like tubes, valves and diode circuits and in Amp simulation often a convolution capture.
Distortion plugins by nature cause sounds to be amplified, while some plugins will control this process others will not and require you to adjust them manually. As a result, significantly louder sounds than expected can occur, And feedback into distortion can lead to rapid and dramatic increases in volume. Monitor and program distortion plugins at a low monitor level while learning them.
In Logic Pro X, you will find several distortion plugins with a similar interface. These are all different type of distortion emulation with subtly different controls. Despite their similar-looking nature, all have a very different end result.
The other type of distortion units we find in Logic Pro X are the Amp Designer and Pedal Boards. These aim to emulate various parts of equipment used to amplify, colour and tone guitars generally But are multi-purpose.
