Additive synthesis starts with sine waves. Sine waves from the harmonic series are combined together to produce musical tones. In this video, twelve sine waves from the harmonic series are added together to produce a rich tone. Then the tracks are staggered so that the harmonics come in one by one. Next the start of each harmonic is faded in to create a smooth blend. One of the harmonics is modulated in level to create further interest. This in itself demonstrates additive synthesis from first principles. The video goes on to load the resultant tone into a sampler so that it can be played from the keyboard. Demonstrations of single note and chordal playing are included, ending with the addition of reverb and sustain pedal.
