Timbral Evolution: Harmonic analysis of classic synth sounds

Posted by & filed under Phase Distortion, Synth DIY, Vintage synths.

This post is a place to gather my thoughts about one of the most important parts of synthesizer design: the timbral evolution of sounds. It also presents the results of my analyses of some classic synth sounds. There have been many methods developed over the years to achieve timbral evolution. The voltage-controlled filter is the first and most obvious. Pulse width modulation and oscillator synchronization are two more from the analogue era. Other later approaches include wavetables, vector synthesis, FM, phase… Read more »

Phase Distortion Synthesis

Posted by & filed under Casio, Phase Distortion.

I heard about this and could find little about it, so I started to investigate. Phase Distortion is one of those forgotten synthesis techniques that someone once built a few instruments with, and then abandoned. In the case of PD, Casio were unlikely synth pioneers to start with, and after a brief flirtation they gave up on the professional market and went back to making home keyboards. The real question is whether, if they’d stuck at it, phase distortion could… Read more »
