Modulation Matrix Question

In the mod matrix of many engines feature there are several destinations related to envelopes: Env Amp S, Env Filter S, Env Aux S and Env Filter D.

Can anyone explain what these mean and how to use them, or point to a preset that uses them?

The manual has nothing specific about those destinations, and I was unable to create a patch where one of those targets produce an audible effect.

Here’s what I tried (in VAP, WAVS and DWA):

I started with an init patch, and latched a note in the arpeggiator (I set up a long gate time so the sustained part of the note is audible

Then I set up the sound like this:

. , .
LFO1
Frequency 0.2Hz
Waveform square (free, unsynced)
Amp envelope
Attack 0
Decay 0
Sustain 50%
Release 0
Filter envelope
Attack 0
Decay 0.2s
Sustain: 0
Release 0
Filter
Env Amount 50%
Modulations
LFO1 → Env Amp S
LFO1 → Env Filter D

Then played with the modulation amount, but nothing I did produced any audible change. However, when I manually change filter envelope decay or amp envelope sustain, the sound changes as expected. What am I missing here?

Edit: better description of the setup

Edit: appears to be a bug, here’s the bug report:

Env Amp S = Env Amp Sustain
Env Filter S = Env Filter Sustain
Env Aux S = Env Aux Sustain
Env Filter D = Env Filter Decay

Depending on your respective Envelope setings, I would suspect you’d most likely hear a difference when sending a modulation source to Env Filter D (Filter envelope Decay) … however probably even more likely if you were to send to Env Amp D (Amp envelope Decay) - hope that makes some sense ?

Of course, that sounds completely reasonable, however for some weird reason that is not what is happening on my Synth. So I’m curious if anyone else can get this to work on their Synth? The other destinations in those engines appear to work as intended.

It seems to be a bug in the software. This is already acknowledged by the team, but I have been waiting for an update for a long time now. Hope they will fix it soon and extend the routing even more in the modmatrix, because this would greatly extend the possibilities for sound creation on the Synth.

Thanks, that explains it.

In that case they should have added a bug report then, so that everyone can find it instead of wasting their time with pointless experiments. I’ll add one right away.
