Crash bug opening current windows build

[geoffeep]

When I run Bespoke, it opens, stays open for about a second, and then crashes.
I don't have enough time to click on the ? unfortunately, so not entirely sure what version it is sorry!

No useful information in the Windows Event Viewer either.
Can't imagine it is helpful, but I'll paste it anyway:

Have you tried removing your Documents\BespokeSynth\userprefs.json file?

[geoffeep]

Gave it a shot, but still instant crash!
I think I'll have a go at compiling from source and see if I can catch it, has got to be a really weird edge case if no one else is getting it

[geoffeep]

Ok building from source and getting somewhere!
The assert is in ModularSynth::GetOutputBuffer.

Channel is 1 going into that function, and the output buffer array only has one element in it.
Still trying to work out what that means, but I'll keep poking it.

[geoffeep]

It is from this function call:

[geoffeep]

Figured it out :)
Arctis 7 Chat setting as a playback device is insta crash!

Hi. What if build Bespoke with the latest JUCE? It should compile.
There is an option -DBESPOKE_JUCE_LOCATION= which can be pointed to the JUCE source tree.

[geoffeep]

I'll give that a try at some point, but I'm pretty ok with using the "Game" mode on the headset for now, I think it is probably the better setting anyway :)

[awwbees]

my surface-level guess is that bespoke doesn't handle things properly when your audio device just has a mono output, it always assumes you have at least 2 output channels. your headphones' "chat" setting is probably just a single channel, which is breaking that assumption. should be a pretty easy fix, although I should figure out how to get (or simulate) a single-channel audio device to properly test it. I might be able to do it with vb-cable.

[geoffeep]

Ah ok yeah, that makes sense.
If you want me to test some code out locally I can do that if it helps!

[geoffeep]

I might try to look at this one myself, if you're ok with that?

As a side thing, I wanted to do a really hacky multi channel output for VST plugins just to see if it was even worth a feature request, and I noticed this comment:
* Until we support multi output we end up with this requirement that
* the output is at most stereo.

So I am going down the rabbithole of trying to understand input and output channels and busses already anyway :)

So regardless how I go on the output channel hackery, handling Mono output might be something I can work out!
I managed to get the code setup, and vaguely understand github, so I'll see how I go :)
