"The Casio VZ-1 lets you combine oscillators into complex sound generators using "EXTERNAL PHASE" mode. There are many possible combinations; in this video we only look at 4 oscillators and combinations of MIX and PHASE mode.
The Casio VZ-1 is an odd and misunderstood synthesizer. In this video we look at how "PHASE" mode (wavefolding) changes the behavior of some of the envelopes.
The story gets more complicated when you add "EXTERNAL PHASE" to the picture but I'll save that for a later video. If you want to read more you can also see the VZ-1 articles on my blog: https://blog.jacobvosmaer.nl/tags/vz-...
"In this video we explore the "phase" output format of the Casio VZ-1. Some people think this is FM synthesis, like the DX7, but it's not. It really is wave folding.
"I learned today that the TX81Z / DX11 coarse FM pitch ratios are divided into four sequences. I sat down with a basic bell sound to explore if I can hear a resemblance.
Besides the harmonic ratios 0.5, 1, 2, 3, etc there are 3 other sequences of ratios which are multiples of 1.41 (sqrt(2)), 1.57 (pi/2) and 1.73 (sqrt(3)). Read more at https://blog.jacobvosmaer.nl/0050-fm-...
