Mono versions of FX Plugins?

[hisefilo]

@orange Well! Finally working. Previous channel configuration of the plugin was cached by Logic Pro X somewhere (no AudioUnitsCache, nor preferences, nothing that I can find)
Changing the plugin name makes it work in Stereo/Dual mono as expected. Thanks mate!
BTW Faust working like a charm in this configuration. (I was expecting stereo Faust .dlls to do something weird in mono plugins)

OKay so I have a client who wants a plugin in mono to work in Logic and PrFools.... can anyone point me in the (currently) right direction for getting this going?

I have a preferences set up like this:

and a routing like this:

Do I have to manually change this to something like:

Or should just renaming and recompiling the plugin work - 'cause I've tried that and its not working for me/him in ProFools....

Any directional help appreciated....

@Lindon you shouldn't have to rename the plugin - it uses the same plugin binary and should detect the channel count automatically.

You don't need to reroute anything, I think it will just call process with an empty right channel.

hmm, well he tells me its not working in ProTools and Logic(AU) and those DAWs wont allow the plugin to be loaded into a mono track....

@Lindon I could be wrong but I think there might be a preprocessor definition you need to add: HI_SUPPORT_MONO_CHANNEL_LAYOUT

so where am I putting this? in the "usual spot"?

[d.healey]

@Lindon Ya

[Lindon]

@d-healey

HI_SUPPORT_MONO_CHANNEL_LAYOUT= 1

???

[d.healey]

@Lindon Sounds right to me (I'm just guessing here about this whole thing)

[Christoph Hart]

HI_SUPPORT_MONO_CHANNEL_LAYOUT=1 has the same effect as if you tick the Support Mono FX box.

Have you cleared the AU cache?

Have you cleared the AU cache?

I've asked him to do this...

Okay he's cleared the caches in Logic and ProTools - and still this will not load onto a mono track

What else should I be trying?

Well this has come up for me today. So all I need to do is check that box and my stereo effect will work on both mono and stereo tracks in Logic? Does it affect VST or just AU?

@d-healey
Yes, checking this box allows the plugin to work in mono on the mono channel.

If your fx plugin is a reverb, stereo delay, chorus, etc., you will want to enable the "Mono to Stereo" feature too. For this, you need to check that box and also add the HI_SUPPORT_MONO_TO_STEREO=1 compiler flag.

“Mono” and "Mono to Stereo" options affect AU and AAX plugins. VST works in all kinds of ways anyway.

@orange What does that do?

@orange What does that do?

Instead of just outputting the channel to mono, it converts the mono channel to stereo.

Generally, users want this for those effects. For example, if you add reverb, chorus or stereo delay to a mono vocal channel, you want the output to be stereo, not mono.
