Envelope or filter trigger problem

[Oli Ullmann]

Hello everyone, hello @Christoph-Hart :-)

I have the following setup:
A synthesizer group with a waveform generator and a filter effect in the effects section of the synthesizer group.

In the grain modulation of the synthesizer group, I have an envelope, and in the frequency modulation of the filter, I also have an envelope with an attack set to 373 MS.

Above a certain release length of the gain envelope, it seems that the filter envelope is no longer triggered when I play notes in quick succession. The filter cutoff is then not turned up slowly but is always played at the maximum value. However, when I look at the filter envelope's own plotter, it looks as if it is being triggered normally. But the signal does not seem to reach the filter.

Am I doing something wrong here? It doesn't matter which envelopes are used. It happens with Simple Envelopes, Flex Envelopes, and even with a Matrix Modulators (the envelopes then come from the Global Modulator Container).

If I'm not doing anything wrong, it's not really possible to publish a plug-in with HISE that has separate envelopes for gain and other effects. But maybe I'm making a mistake or there's a workaround.

It also doesn't matter whether I use HISE's own filter or a filter via a hardcoded effect.

I've created a short video that illustrates the problem (please watch with sound):

Here is a minimal snippet that illustrates the problem:

PS. It shouldn't be the reason, but I think I'm using commit c49bcf3 from January 21. Unfortunately, HISE doesn't show me any commits, but I'm pretty sure I'm using this commit.

@Oli-Ullmann weird looks like a regression and it only happens if you replay the same note. I‘ll take a look later.

@Christoph-Hart
Great, thank you very much. Since it concerns fundamental modulation, I think that's an important one.

[HISEnberg]

@Oli-Ullmann Can confirm your issue. It sounds rather similar to what I posted here (minus the noise about global modulation). I.e. Filters + Envelopes break down in a polyphonic setting in HISE.
