Audio inputs aren't working anymore

[ustk]

@Christoph-Hart Since I've pulled the last commits to my branch I cannot have audio inputs anymore.
The culprit seems to be the - added audio & MIDI clip file drop to DAW timeline simulator commit.

I still FORCE_INPUT_CHANNELS like before but nothing... (so it's not related to the USE_BACKEND flag that comes with that commit, which anyway is 1 obviously)

So is it possible for the two friends to coexist? (audio IN and Timeline Simulator)

@ustk Might be related to this - https://forum.hise.audio/topic/7055/fix-channel-resizing-in-hise-broke-my-routing

[ustk]

@d-healey Well that's what I thought at first so I reverted this one but with no luck.
It's the one before that causes my troubles (the input stream is back when reverted)...

Two commits, two issues

[ustk]

@Christoph-Hart Have you had the time to analyse this issue, please?

[ustk]

Bump bump

[ustk]

@Christoph-Hart Hmm... Nothing on this issue?

[d.healey]

@ustk Have you figured out which commit caused the issue?

[ustk]

@d-healey In the first post ;)

[DanH]

@ustk did this ever get solved?

[ustk]

@DanH I'm not sure actually, as I use my own Hise branch where I reverted the commit that was causing the issue...
And for whatever reason, I can have my branch running in Xcdode with no troubles while the develop branch always fires an assertion, but this might not be related to that reverted commit...

[DanH]

@ustk ah yes I remember you edited the source code to enable the inputs, is that right?

[ustk]

@DanH Exactly

[DanH]

@ustk was it a simple edit?!

[ustk]

@DanH we talked about it together here :)

[DanH]

@ustk haha! I thought I remembered something

13 files... that's a lot! If you're willing to share details let me know, no problems if not! :)

Would this be possible to have it fixed, please, Christoph?

[ustk]

@Christoph-Hart Found the culprit... Is it safe to do this?

void BackendProcessor::processBlock(AudioSampleBuffer& buffer, MidiBuffer& midiMessages)
{
#if !HISE_BACKEND_AS_FX && !FORCE_INPUT_CHANNELS // <- Added the FORCE_INPUT_CHANNELS preprocessor def
	buffer.clear();
#endif

If ok for you I'll push a request

[ustk]

@Christoph-Hart Hmmm... Something else happened on top of everything. Somehow, the input is directly sent to the output internally.

It's always been the case since I opened up the possibility of activating the inputs (and I think it's totally normal), but a muter in a container always solved this to keep the separation.

Now even with a muter, the input is still leaking into the output and completely ruins my project. I wonder if this can be related to the recent channel fix/improvement you've made. Any idea how to solve this or at least where to look?

[ustk]

@Christoph-Hart Seems that I found the culprit, but please I need your light to see if it's safe.

I re-enabled the following lines that were removed by the commit https://github.com/christophhart/HISE/commit/799694e1f330fd82aa827a36b756ffa4e14d4d7d,
but this time with an inverted preproc like in the screenshot (it was !FORCE_INPUT_CHANNELS)

Without this fix and with the FORCE_INPUT_CHANNELS flag enabled, audio input is summed twice because I do this too to get the inputs working:
(this explains why a muter just removed one part of the signal while the rest was still going through)

void BackendProcessor::processBlock(AudioSampleBuffer& buffer, MidiBuffer& midiMessages)
{
#if !HISE_BACKEND_AS_FX && !FORCE_INPUT_CHANNELS // added !FORCE_INPUT_CHANNELS to keep inputs
	buffer.clear();
#endif

Will this cause big problems?

[Christoph Hart]

@ustk yes this will mute any sound created in child containers which is why I pushed that commit.
