Stereo effects plugin summing to mono in FL studio

[d.healey]

@orange So it's possible for a mono track in Logic to have stereo output?

That’s what HI_SUPPORT_MONO_TO_STEREO is being used for

Just follow the same procedure for AU plugin export; The plugin will convert the mono channel to a stereo channel with that flag.

Same for AAX on Pro Tools too.

@Christoph-Hart Given what @orange has said, I think it would make sense to prevent HI_SUPPORT_MONO_TO_STEREO from affecting VST plugins. Otherwise it makes it more cumbersome to automate builds as we need to switch out this flag in project preferences between building VSTs and AU or AAX.

[d.healey]

Oh actually looks like I can set the definition through CLI, so if I export VST and AU separately I can change it in between.

MONO TO STEREO VERSIONS ---> With different Plugin Code and Plugin name. I add - m to s afterfix to the name. Both HI_SUPPORT_MONO_TO_STEREO=1 flag and Support Mono FX is enabled

Is anything else needed? In Logic my plugin is only showing up with a mono option even though I have both of these things set. And when I try to load the plugin it gives me an error. Loading on a stereo track works fine though and everything passes in AU validator.

@d-healey Have you tried loading the plugin on the mono channel instead of the stereo channel?

mono-to-stereo versions appear on mono channels only

Also, mono to stereo version should have a different (4 digit) Plugin Code and Plugin Name

Yes that's what I was doing.

Doesn't appear at all for me.

@d-healey Does it happen if there is only mono-to-stereo version in the components folder?

Maybe AU cache needs to be cleared.

[d.healey]

@orange Yeah I only made one plugin. How do i clear the cache?

@d-healey

Close Logic Pro X.
Using macOS Finder go to “~/Library/Caches/AudioUnitCache/” (without the quotes).
Manually delete the com.apple.audiounits.cache file (to force a complete new plug-ins scan).
Re-open Logic Pro X.
Reboot the computer (mandatory).

I'm trying to test different configurations but my plugin doesn't show up unless notarized and codesigned which is slowing me down. Is there a way to disable this so that Logic will show uncodesigned/unnotarized plugins?

[Christoph Hart]

@d-healey if you build the plugin on the same machine then it should skip the notarization test. At least if you're running on native hardware, with a VM it might be glitchy.

Curse you Apple!!!!!

[d.healey]

Aha I finally got it to work, Christoph was right, the force stereo output option must be enabled to get mono -> stereo!

However I notice that stock AU plugins show both mono -> mono and mono -> stereo under a single plugin, so this is what we should be aiming for, there shouldn't be a requirement to create two separate plugins.

This appears to be the solution https://forum.juce.com/t/how-to-enable-mono-stereo-option-for-plug-in-within-logic/41545/2

@Christoph-Hart What do you think?
