Many of you have likely heard the phrase, “You can never have too many VCAs.” The ubiquitous and humble VCA is one of the simplest, yet most versatile modules. Some folks are left scratching their heads wondering why. Typically one puts a VCA at the end of their patch to control sound duration and volume with the use of a modulating envelope. However, what if you were to put your envelope through a VCA modulated by random CV then send it to the final VCA? Well, you have now randomly modulated the level of you envelope to get dynamic volume on each trigger of your sound.
Using the same idea as above but with saw wave LFO into VCA and modulate with an envelope to get a rising saw. The green wave shows what the final output would look like.
If you modulate a sound in a VCA with some other audio, then you get Amplitude Modulation or AM synthesis, If the VCA is Bi-polar and you do the same, you get Ring Modulation. What would AM processed by RM sound like? Stack the VCAs, put a sound into one controlled by a square wave LFO and run that sound into another controlled by and Envelope and then a third controlled by random. Route modulation through a VCA first and only let that modulation pass when you want, instead of continuously. Create your own CV controlled Send/Return. The options are many.
Explore the many possibilities of VCAs. Create a patch and use VCAs in no less than 3 different ways. Try to use every VCA at your disposal, the more the better. Try to use them in as many ways possible.
