How can you tell if you have a VST2 or VST3 license?

I have no idea, you don't need a license if you're releasing under the GPL though.

I'm going to have to check again, for some reason I thought the VST SDK I built HISE with was a binary, and not source code. I remember reading that VST3 does have a GPLv3 license, but I didn't realize that was what I was using to export my VST2 and VST3 plugins.

[hujackus]

So I looked into it and HISE is not built with source code that falls under GPLv3 and therefore a VST3 license is needed from Steinberg. I was reading into which versions of VST3 have the GPLv3 license and I found that not everything HISE needs to compile falls under GPLv3.

The boilerplate at the top of all the VST SDK code is from 2016 and has no mention of GPLv3.

You can see this here: https://github.com/christophhart/HISE/tree/develop/tools/SDK
[3rd party SDKs
In order to build certain configurations, you'll need some 3rd party SDKs that can't be distributed along with the rest of the source code for licencing reasons. Instead you'll need to register at each company and do everything they tell you to do in order to get their SDKs.]

@hujackus ah that needs updating, the vst3 SDK is included with the source code

So as it stands, I can't compile HISE without a VST3 license because the VST SDK it uses hasn't been updated to the version with the duel license(which includes GPLv3).

[d.healey]

@hujackus Oh interesting. @Christoph-Hart What's the reason for this? Is the newer version not compatible with JUCE 6?

[hujackus]

@d-healey I did some more digging. There is some VST3 source code under GPLv3 that is included in the JUCE portion of the HISE source code. Here is a link to that code.

I'm still looking through the code to find other places where HISE uses non GPLv3 source code. Would it be easier to search the HISE-develop\tools\SDK\VST3 SDK directory and delete all the files that don't have the dual license and see what compiles?

You could try it.

@hujackus I wouldn't worry about it. Just do your thing. I don't think Steinberg will mind.

So I tried it. I deleted the HISE-develop\tools\SDK\VST3 SDK directory and I recompiled HISE Standalone without any problems. I opened up my project in HISE and exported it to VST3 and immediately got an error "VST SDK is missing".

I put back the VST3 SDK directory, but removed the vst2.x subdirectory and I was able to successfully export it as a VST3. I disabled VST3 support and it exported as a VST2 successfully.

It seems HISE does require some of the files in HISE-develop\tools\SDK\VST3 SDK, but does not use all of them (all the vst2.x files for example).

I'm just trying to comply with the open source terms set by HISE. It is impossible for me to release my VST2 version because of not having a VST2 license from Steinberg, and even if I did have a license I would not be able to release it because HISE requires the project to be fully open source under GPLv3 (unless I purchase the Indie commercial license).

In fact, nobody can release a VST2 under the HISE Open Source License. It was never possible. Therefore, I must consider VST3 only if I am to use HISE. It has taken a lot of review to come to this conclusion. Right now I'm just trying to find out if it is true that I don't need a VST3 license from Steinberg if I only release using GPLv3.
