Level Modulator
PM osc saw 2 square morph
If you have played a little with the PM oscillator you will no that carrier:modulator ratio 1:1 gives a sawtooth like spectrum and 1:2 gives a square like spectrum. This idea uses a LevMod (ring modulator) and level shifter to shape the sine through to a 2X frequency sine. So a signal applied to the Mod Depth input will morph from saw-ish to square-ish.

Because the modulator is the output of the carrier, this is known as feedback FM, the Phase mod level is quite sensitive and will break into noise if set much higher.

The example patch contains two circuits as shown and filter envelope etc.

Amplitude Modulation (AM) and Frequency Modulation (FM)
Amplitude Modulation (AM) and Frequency Modulation (FM) are actually Vibrato (FM) and Tremolo (AM), but with the modulation being in the audio range. If you'd normally use a LFO for Vibrato, for FM a "regular" oscillator is used.

For examples on FM look here.

The AM examples below are by BlueHell:

Brown noise, pink noise, whatever. Read much more about it in Roland Kuit's RM and AM-workshop on Clavia's webpages.

Pitchcontrol with RM
The ringmodulator can be used to transpose pitch. Read much more about it in Roland Kuit's RM and AM-workshop on Clavia's webpages.

VOSIM
This is a close redo of VOSIM, a synthesis method that creates vowel-like sounds. It works by wrapping a Sin^2-wave in a downramp sawtooth, thus decreasing the amplitude of the Sin^2 wave (in the example below we have four Sin^2-waves in one sawtooth). Read more in Rob Hordijk's workshop on VOSIM on Clavia's website.
