Does inserting something into the right inlet of *~ always mute its output? I have multiple cycle~ objects in an additive patch I am working on and want to modulate the combined waveform with a simple LFO subpatch that I can turn on or off.

The [*~] object multiplies two audio signals (sample by sample). If nothing is coming in one of the inlets (or a signal of amplitude 0 is coming in one of the inlets) the product of the two signals will be 0. So, when dealing with audio signals in MSP often it's valuable to think of "turn on or off" to mean reducing a signal's amplitude to 0.

Below is an example. See also MSP Basics Tutorial 2: Adjustable oscillator.
