Making a tremolo patch

Let's try out a really simple patch - a tremolo. This showcases two very powerful blocks for processing control signals such as the pot inputs.

#1 - the Scale/Offset block lets you constrain the low and/or high range of a control to make sure that the thing that you want to adjust is set just right.

#2 - the Power block lets you set a control so it comes in faster or slower relative to the rotation of the pot.

Further explanation of the "Tremolizer" block is in order. If you use the width control on the Sin/Cos LFO, then this will adjust the swing around the center point (which is 0 when the output range is set to -1.0 to 1.0 and 0.5 when the output range is set to 0.0 to 1.0).

What I really want is for the LFO signal, going from 0.0 to 1.0, to REDUCE the gain of the audio signal as the LFO amplitude increases. Otherwise you are left with the possibility that then the width is 0, you will have no volume at all coming out of the tremolo. The Tremolizer uses some clever internal scaling to give you this without having to think too much about it.
