Y u no 64 bit VSTs?

BTW. What is the reason juce can’t build 64bit VST’s on Mac? There seem to be bundles of them out there. Am I missing something?

I can’t answer your question, because i’m able to build 64bit vst plugins on mac.

I can’t answer your question, because i’m able to build 64bit vst plugins on mac.

When you say you “can’t build them”, what exactly is stopping you?

Hang on a second now… It does seem to work. (?) Let me explain… Where are my glasses…

I am running on a clean system so I haven’t installed a 64 bit VST host, only the vst host I have built myself with juce.
It’s the juce vst host that doesn’t do 64 bit! Is that so, and why? The vst host doesn’t get a 64 bit build.

Let me clarify. The juce vst host doesn’t do 64 bit builds. Is there a reason for that or is the code not updated?

What do you mean it doesn’t “do” them? Are you saying the host won’t build in 64-bit mode? If so, what are the errors?

I mean, that the class “VSTPluginFormat” is inhibited from being compiled, (and used in the AudioPluginFormatManager) through a series of statements such as:

Ah yes… I’d forgotten about that. Can’t remember the exact reason for it… Anyone tried getting it to run in 64-bits?

Considering the general readiness of 64 bit code in juce, I would guess this part is also quite there. I know you have many other things to do, but if it would be possible for you to look into this, I would be very grateful!

I also need this for a project and it seems a bit more complex than a few switches. I think the problem boils down to a lack of 64-bit Carbon support in juce_mac_CarbonViewWrapperComponent. When trying to compile this file in 64-bit mode I get a ton of "undeclared identifier " compiler errors. Perhaps there are different versions of these calls for 64-bit Carbon. Is Carbon even needed as per the “#error “To build VSTs, you need to enable the JUCE_SUPPORT_CARBON flag in your config!”” in juce_VSTPluginFormat.cpp?

Anyway to get the plugin host demo to this stage I had to comment out the ! (JUCE_MAC && JUCE_64BIT) in juce_VSTPluginFormat.cpp line 29 and juce_AudioPluginFormatManager.cpp line 58. Then I had to add JUCE_SUPPORT_CARBON=1 to the Introjucer’s pre-processor definitions hence all the errors described above.

Any thoughts welcome.

Hi Dave,
Carbon is not fully implemented in 64 bit. If you want 64 bit you need to go Cocoa. It’s as simple as that. I have a vague recollection that Carbon has a few 64 bit calls implemented but essentially its a no-go.

Without looking at the code, I assume that the 64bit VST plug-in code provided bu Juce is implemented in Cocoa. What remains by Jules to do is to add the same things to the host.

Yes, I was just wondering if there is anything that necessitates VST using a Carbon window or if this could be updated to a Cocoa one. Is this just legacy code from the old Carbon days of the library?

I don’t know for sure if 32 bit VST plug-ins require or expect a Cocoa or Carbon host window, but 64 bit VST plug-ins got to be Cocoa. Neither do I know if the VST plug-in would have a way of knowing if the host window IS of Carbon or Cocoa origin. Mac isn’t my strong side. I rely on Juce for this kind of compliance.
Personally, I wouldn’t rely on the VST documentation for this information as my experience is that plug-in devs not necessarily follow the docs all the time. I also think Steinberg is way to vague on matters that count, but that’s beside the point.

Hi guys,

I got the same problem so I managed to patch juce_VSTPluginFormat.cpp and juce_AudioPluginFormatManager.cpp to be able to compile with VST support in both 32 and 64bit modes.

My only concern is that I don’t have any 64bit-only VST to validate the change, nor do I have old-school 32bit Carbon VST to ensure that it is still displayable with the patch. Of course I’m going to make a 64bit VST real quick to validate the first point, but for the latter, I will need your help.

Here is the patch (I don’t have the latest tip so the line numbers might be wrong for your files):

Brilliant. If it works I’m going to motion to Jules to have a look at it so it’s actually integrated.

Ok the previous version was only half working, since it could not display the 64bit VST editor window. I hacked the VSTPluginFormat code a bit more to replace the CarbonViewWrapper by a plain NSViewComponent in the case where JUCE_SUPPORT_CARBON is not set.

The result makes this already messy class a little bit more messy… but at least it works!

Jules, could you include that change in the master? I can rebase the patch on the tip if it makes it easier. But I guess you will want to review and probably adapt the styling to your taste?

Cool stuff, thanks! I’ve checked in some changes that should do the job - would appreciate any sanity-checking!

Ran the plugin host demo, instantiating all the 64 bit plugins I have on my system, and it seemed to work like a charm.

Thanks for the quick integration!
