Linear versus Exponential VCAs & Envelopes
Some VCAs are labeled as having “linear” response, some are labeled as having “exponential” response, and some have a switch or even a continuously variable control to go between the two. Which one should use you use, and when? Of course, the best answer is “whichever...
Patching Exponential FM
One way to create more complex waveforms (and therefore, harmonics) than traditionally supplied by oscillators is to use one oscillator to modulate the frequency of another. In this article I’ll describe how to set up an “FM” (frequency modulation) patch, and include a movie from my Learn Modular Synthesis course that demonstrates the “exponential” flavor of FM.
