Noiselab FM Synthesis TUTORiAL

The origins of FM Synthesis date back to the 1970's. Frequency modulation is a type of synthesis that is heard in many genres of music including house, pop, dubstep, EDM, electronic music, and more. Popular synthesizers include the Yamaha DX7 keyboard and the software synth Native Instruments FM8 - both of which have been used by notable artists.

This course is designed to teach those who may not be familiar or comfortable with synthesis about frequency modulation, and how it can be used as a method of synthesis to create very unique sounds and textures. We will start by making the connection between frequency and pitch, and then introduce the basic concept of frequency modulation by using an LFO to modulate the pitch of a sine wave. By increasing the speed of the modulation, the viewer will notice that it sounds less like the pitch is changing and more like the overall timbre is changing. Once this is understood, we will dive deeper into the Operator instrument in Ableton Live and discuss various ways we can take advantage of frequency modulation by utilizing the four operators, different routing algorithms, and different sources of modulation (LFO, Pitch Envelope, Filter Envelope). At the conclusion of this mini-course the viewer will be able to create unique sounds from scratch by utilizing FM synthesis.
