Envelope follower

Thanks Narcissus...
very helpful explanation ..

Hey again. I was trying to use the analog inputs on the snow, so decided to try the envelope follower, so I did a google search for it, and the result that popped up was this page ..a question I myself had asked a little while ago.
Anyway..I re-read it, and this time understood a little better, since recently I learned about envelope followers in FL studio, using something called a Peak Controller. The same way a bassline is sidechained, the peak controller can be linked to any destination or parameter in the DAW. I had been sidechaining bass for a while before, but only realized the potential of the peak controller/ env follower, recently after reading about it online. Great little technique. I enjoyed using it on a distortion plugin, so as the bass got louder it distorted more.
Although I have grasped the concept of env followers, quite well, I am still having a hard time implementing it on the Virus.
I am not sure how to set it up and use it. For example,on the input mode patch, FX page - activate input- static input, and then activate the Env follower from input. WHat is the env follower affecting in this case ? is it acting on the input signal itself or can I play the synth oscillators and stuff at the same time as input ? will the env follower affect the oscillators internally ? can it modulate anythig apart from volume and filter cutoff ?also does each of the 4 parts on My snow have an individual env follower or can one stereo analog input affect the env follower on all 4 parts.
I wasn't really able to figure it out. something did happen, but I couldn't figure out what exactly was happening.

Thanks

Not to hijack here, but will an envelope follower allow for treating the incoming signal unaltered? As in if I was to send it an external LFO or envelope signal, would the envelope follower alter the envelope or LFO wave no matter its settings, or could it, with the right settings, just echo the wave as it was originally?

If so, will any of the viruses allow this?

the signal can pass untouched, yes. you can use just the fx or filters on it without the envelope follower, therefore preserving the signal as is.

No I meant as a modulation source. I might have misunderstood something though. What I'd like to be able to do is to put a line level modulation wave in there, say to modulate filter frequency, without the envelope follower changing the shape of the signal wave, like rounding off the edges etc. But is this at all how it works, and is it possible to do this with one of the viruses?

what the envelope follower does is replace the filter envelope.

you can use it as a modulation source in the mod matrix, by choosing "filtenv" source. so if you were to put this volume modulated wave in there to modulate the filter frequency, it would instantly work like that. you'd use the env amount knob to control how much it affects the filter, and the attack and decay knobs are usable to, as well as the sustain knob that acts like an input knob for the incoming signal.

Wow that's nice to know! So if attack is set to 0, decay to 64(?), sustain to 127 (for unattenuated input level(?)) and release to 0, then the filter frequency is modulated by the original, unaltered wave, and modulation depth is then controlled with the env ammount knob, is that correct?
