Modulation in MUX?

[DruMunkey]

I've got a quick pre-sales type question I've not been able to figure out from watching videos...

A bit of context:

I will mostly likely want to use MUX with VST's. That is, I'm mostly interested in control streams, not synth/sound (at least creation-wise).

So, sinc eI'm mostly using it to control VST's, can someone tell me how modulation sources "act" on VSTs?

For instance, Can I use the VST's native interface to set a parameter (e.g. cutoff), then send a MUX LFO to the cutoff control so that all the LFO values are "added" to the VST set value? Or does the LFO value "take over" the VST's value?

I'm looking for a solution that will allow modulation to be "delta" values, not "set" values.

Here's a REALLY simple example:

LFO Step : Value
1:0
2:5
3:10
4:3
5:0

VST Cutoff value = 50

VST values @ each step I want when LFO Runs

1:50
2:55
3:60
4:53
5:50

What I DONT want but most DAWS seem to do:

1:0
2:5
3:10
4:3
5:00


Does this make sense?

Most values in Mux / MuLab are expressed as percentage ranges, Eg. -100 to 100 %, that said
you can draw out the shape of your LFO's however you want. So as long
as you can express your desired values as a percentage of 100 you should be good to go.
Shapes can be uni-polar or bipolar and you can specifically set the length of the oscillation
in milliseconds, beats or whatever.

You can also use additional modules to vary or randomize the parameters of the
primary LFO for varying amplitude and whatnot.

So yeah the system is pretty flexible. If I understand you correctly I would think
you should be able to accomplish what you want pretty easily.

*Oh and regarding the vst parameters, Mux of course has no control over the vst.
I imagine a vst parameter has to adhere to the vst standard for it to work with automation,
Mux simply does the same I would guess.

One easy way to find out is to try it. MuX runs with all features enabled in demo mode, just emits a soft noise on its outputs mixed in.

Say you want to MuXify a VST instrument. Insert the MuX VST Instrument into your host. You'll get the "Basic Synth" patch selected. Switch it to "Empty Synth" then drop into the modular area and replace the Polysynth module with the VST instrument you want to modulate. I'm using MDA Piano in this example. When you've chosen your VSTi, its front panel will display. The MuX container toolbar will show one of the VSTi parameters selected. Wiggle one of the VST controls and the selected parameter in the MuX toolbar changes. OK, so that means MuX knows what's going on in the VSTi. If that doesn't happen, then you may have a VSTi that doesn't work according to the standard.

Next, in the modular area, add a Parameter Event Generator module, link it's output to the VSTi event input, then open it up and pick one of the VSTi parameters to modulate. I'm picking "Muffling Filter" -- because it shows something important. The default value in the VSTi is showing 20%. The default value in the Parameter Event Generator is showing 50%. If I now move the Value knob, the VSTi value jumps to match the Parameter Event Generator value.

OK, so we want a slow LFO with a limited range wobbling that muffle. Add an LFO module, connect it's (green) modulation output to the (green) modulation input on the Parameter Event Generator. Watch that muffle wobble! Need to slow it and tame... Open it up, set Frequency to 0.1Hz and Amplitude to 5%. There... Hm. It's wobbling around 50% but I wanted it at around 20%...

So for that, we can add a Modulation Mapper. As we've already set the Amplitude, this is just to control the offset. Insert the mapper between the LFO (to first green input on the MM) and the Parameter Event Generator. Set the Offset to 30%. Now that's sorted - oscillating over 10 seconds from 15 to 25.
