Modulation signal smoother

As said in the title, I'm trying to smooth radical modulation signal value changes (like square LFO). For the moment, I'm using an modulation --> audio signal converter, then an audio envelope follower but I'd like to know if there is a way to achieve the same result without converting modulation signal into audio...

There is no more direct way yet and indeed going via audio costs a bit more cpu, but at least it's possible and the audio rate modulation will always be best quality so the cpu cycles are not wasted

Thanks a lot for the info ! If it doesn't take too much cpu power, I'm happy ! 
Well.. A smoother module is simply inserting a ramp values when it receives a value. And often, you may set the time it takes to reach the value it received.
Like an interpolation https://en.wikipedia.org/wiki/Interpolation
At the output, instead to have a staircase shape curve, you'll have a slope.
Sometimes, in a synth, with some presets, since there is only 127 filter cutoff points, you may hear like a zip noise when changing cutoff value, and with a smooth module, this unpleasant noise will disapear. For instance, my Powercore Virus has a smooth feature.
If you modulate the amp gain with square LFO, you'll hear clics every time the gain value is changed by the lfo. In Mux, convert the lfo modulation signal into audio signal, to go thru a envelope follower, its output is modulation signal, go to the amp gain input and set the envelope follower attac & release time to get slow or fast slopes.

I see now, how about just editing the LFO shape, would that not work, or is there more to it than that ?

Well.. Lfo was an example, with some other modulation signals, you can't edit nothing.

Post a screenshot of your MUX window JoPo.
I'm thinking I might want to modulate my SE-02 using CV in for better control of its Filter.
I want to add more resolution to my Expression Pedal, which will control cutoff.
It works pretty good right now but having used SilentWay before the quality of audio as a modulation source is vastly superior.
I'm running i7 4790k CPUs @ 4.4GHz so I welcome more CPU Cycles getting used.
I want my money's worth.

I must say, as Silent Way user, that Mux modular allows me to do the same and even much much more to my Scope modular via asio drivers ! It is a Sonic Core product, working on their AMAZING hardware unit Xite-1.

Much much much too unknown ! A bit like Mutools ! They devote their time to develope their products instead of marchandizing ! But from very far the best audio DSP system on the market !
I didn't notice a less good resolution modulation signal by sending them via asio in comparaison with Silent Way.
You just have to convert modulation signals into audio signals in Mux, then send it to your audio card, just like for Silent Way... But you certainly already know that.
To smooth modulation signals, first, you have to convert them into audio signal in order to input them into an envelope follower module. In this module, you can set up attac & release time, and it outputs the modulation signal with ramp that takes the time you entered to reach any new value.
When I'm building any modular patches (in Mux or Scope Modular or Reaktor), I always check how behaves the signal (thanks to modulation/audio/event monitoring modules) before and after a module, to be sure of what I'm doing. Et voilà !

For smooth modulation you can also use a simple setup like this:
modulation to audio converter > LP filter > Audio out/or audio to modulation converter.
There are also other tricks but this is the simplest one:)

Right ! It works very well with LP cutoff very low but time ramps are not customizable..

Excellent, thanks JoPo and Taifunk.
I like options.
Another I will try is the Behringer FCV1000 Exp/CV Pedal.
I can still control everything on the SE-02 with FCV 1/4 Expression.
But the CV Out on FCV will go to VCF CV Input on the SE-02.
I can't hear any difference in sound quality from my SE-1/SE-1X over the SE-02.
Impressive control features too.
Just can't use the ModWh or Expression to control Cutoff.
I need both hands to play, so the high resolution ModWh sounds great, but impractical.
Expression to Filter, very smooth but too much play/lag on the Expression Pedal.
These were my concerns.
I'm confident I'll get what I want using MUX or the FCV.
Whichever works best wins.
