Container modulators not working

[d.healey]

@christoph-hart I've updated the files in dropbox now. No glitches on Windows. Going to test debug mode on Linux now. There was a jassert juce_file.ccp line 134 on Windows in debug mode.

Debug build on linux:

JUCE assertion failure in ModuleBrowser.cpp:158 - this just happens on initialisation
I get a lot of nasty noise in the debug build - I've added another 8 second audio file to the dropbox zip file demonstrating this - but no assertion messages related to this.

With more careful listening I think the glitches are actually present even without the LFO. I'm not hearing them as strongly in my sampled instruments as I do with just the sine wave generator though.

I also tested the Windows build in a virtual machine on my Linux system and there was no glitches so this does seem to be a Linux issue.

Hmm, it seems as it sets every 8th sample, but the rest is silent, which correlates with the downsampling factor of the modulator system.

Can you change the downsampling factor and try again? It's a preprocessor macro in hi_core/LibConfig.h:

#ifndef HISE_EVENT_RASTER
#define HISE_EVENT_RASTER 8
#endif

Around Line 66. Change it to #define HISE_EVENT_RASTER 1, recompile and try again. If this solves the issue, we're still not sure what caused it, but on the right track :)

BTW, the best way to debug issues in the modulator system is by creating a dummy wave file with a fixed value of 0dB and loading it in the Loop player:

DC Wave file

(Make sure you turn your speakers down, it's "loud"!)

@christoph-hart That seems to have fixed it

[Christoph Hart]

Found it. It was indeed a code path that was just executed on Linux and contained low-level SSE optimizations that didn't work apparently :)

I've just pushed the change. Please check if it solves it - and make sure you roll back the manual change you did otherwise you won't be able to test it...

[d.healey]

@christoph-hart Excellent, that did it! Thank you. One strange thing I found though, changing the volume of the sine wave generator (doesn't seem to affect samplers) changes its pitch...

Is the master chain modulator issue a simple fix?

[Christoph Hart]

Wasn't exactly hard :)

@christoph-hart Yey, going to build now!
