Good information hear, learned a few things.

1 way I use Mod envelopes is like a sort of "fade-in" effect, for example could set your mod envelope to control PWM on an oscillator. Set the attack on the envelope to maybe 1 second, hold down a key and listen to the PWM increase over the 1 sec period

loads of stuff can be done with Mod envs and LFOs, really depends on what synth you are using

Cryo - Care to give us the dirty on Mod Matrix's? I still don't think I know how to use them to their fullest.

Sure. I'll use Z3TA+ as my example since a lot of people have it.

You can see the mod matrix in the lower left-had portion of the GUI. Mod matrices are essentially just slots that let you choose assignable (i.e., not dedicated) modulation sources and destinations, the amount of modulation, and any additional controllers. So, in the Z3TA example, there are fields for Source, Range, Curve, Control, and Destination. You can see that in the first slot of the example, LFO1 is used as the modulation source. By clicking on the arrow to the left, you could change that to any one of several dozen available modulation sources, which include other LFOs, envelope generators, oscillators, XY pad, etc. The Range control is similar to a modulation amount control on most other synths' mod matrices, except that it is two-sided in the case of Z3TA+. In other words, you aren't stuck with 0 to 100% - you can choose a low and high value (e.g., 20-80). The Curve is just how fast the effect responds to a Control (not many other synths have this parameter in their mod matrix). The Control slot allows you to specify an optional controller, such as a mod wheel, aftertouch, breath controller, etc. for manually adjusting the modulation amount or another modulation source, such as another envelope generator or LFO1; without a controller specified, the amount will simply be determined by the Range (or Mod/Amount knob in other synths). The Destination field is where you specify the parameter that will be modulated by the Source.

So, in the case of the first slot, Oscillator 1's pitch is the destination and it is being modulated by LFO1 at a range/amount of about 20%, with no additional control specified. In the second slot, EG1 (Envelope Generator 1) is modulating the cutoff frequency of all filters at an amount of 100%, with no additional controls specified.

Gotta get back to work! HTH.

I made a video about this and posted more explanation here:
