Issues in exported AAX plugins: drawing panels and buttons, sliding a panel

[gorangrooves]

@Christoph-Hart Thanks very much! This is very helpful. I'll be debugging as you suggest and will report back my findings asap.

[gorangrooves]

@Christoph-Hart I ran the initial test with repaint. After 5 sec, the elements on the interface showed up. The sliding panel (that uses a timer) still doesn't come up.

I've discovered several more issues related to the "onNoteOn" callback.

• I have "note indicators", small circles that light up when notes on the keyboard are played. They are not showing, and the "incoming note#" display on the top is also not showing any notes played.

• "Learn MIDI note" is not working either. The way it works normally is that you enable the learn button next to a note, and when a key is pressed, it gets assigned to that instrument.

So, this seems pretty severe. I will now try different HISE commits to try to narrow it down.

@Christoph-Hart I am unsure if I am properly moving back in the commits.
In the Sourcetree, when I right-click on a commit I want to move back to, which option do I select?

I was using "Reset current branch to this commit." It places the "HEAD" label on that commit. It looks right, but I am unsure if it is.

@gorangrooves Use the commandline git checkout #commithash

[gorangrooves]

@d-healey Thanks, but I'd rather not. I want to stick with the Sourcetree GUI. I find it to be easier, but I need to ensure I am doing it correctly.

@gorangrooves if you're referring to GithubDesktop, then a right click on any commit, create new branch from this commit (or something similar) is what you want, and just give it a name.
Delete that branch when not needed anymore

[gorangrooves]

@ustk Thanks. The software I am using is Sourcetree, which is the same as what Christoph uses. There are several options. While I understand the overall concept and what I am trying to do, I am not sure if I am doing it right.

[gorangrooves]

@Christoph-Hart I confirmed that "Reset current branch to this commit" is the correct way.

Here is how my travel through time went for the last few hours. I am using VS2022.

• I first tried compiling AAX using the 2.6.1 SDK going back several months, and only the latest commits would compile the plugin.

• I swapped the AAX for the earlier 2.4.1 version. When I wasn't able to compile plugins with it either, I just tried to compile HISE.

• I went as far back as Oct 2022 and tried dozens of times to compile HISE, moving up a month or a couple of weeks. Up until August 2023, it is impossible to compile HISE as it is getting a lot of errors and warnings.

So, the earliest I can compile is August 10, 2023. I compiled the AAX with that version, and the issue I reported still exists. This is using the old AAX SDK.

So, since I am unable to compile anything earlier than this date, this approach is a dead end.

Next step: create a simple project with just one issue, like do something on NoteOn?

[Christoph Hart]

@gorangrooves have you resaved the projucer file before compiling after jumping around in the git history? This will solve most compile errors (there are a few intermediate states which don‘t compile but most commits should work.

[gorangrooves]

@Christoph-Hart I did. I would close Projucer, open updated Projucer project and clean build in VS before compiling.

[d.healey]

@gorangrooves Something might be messing up in your local repo, you should definitely be able to build HISE all the way back to the first commit, except for those occasional commits that no-one can compile.

[gorangrooves]

@d-healey I'll try again. I'll delete everything locally and start fresh.

[gorangrooves]

@d-healey @Christoph-Hart I deleted the local HISE repository and started fresh. I was able to compile HISE from Jan 5th, 2023 and AAX.

My plugin displayed the GUI properly, but panel sliding (timer) and onNoteOn are not working. That leads me to believe that there are several issues introduced at different HISE development stages. I will continue to hunt down and document exactly what happened and when and will report here.

[gorangrooves]

@Christoph-Hart I remembered I still had a backup of my old plugin version where those problematic features were working. I compiled it with the newest HISE and latest AAX SDK, and all those functions worked. The panel slides out, on NoteOn works. Whatever I had then working, it works now.

So, the problem lies somewhere in my project, but only for exported AAX.

Where do I go from here?

Did you use git to keep track of changes in your project?

[Christoph Hart]

Yes, git would be super nice for this. If you haven't used git yet, it's time to do so, then commit your earlier version and then overwrite it with your current project it will show you all changes.

[gorangrooves]

@Christoph-Hart I've been meaning to do the Git, but am not familiar enough with it and am pressed for the time.

I've restructured the project significantly, so I am not sure Git would be of much help other than telling me that everything is different now I used to have all sections of the project on the onInit. Now, they are split into files integrated with include.

I guess this will be a trial-and-error process. If I can at least get to the bits of code that are misbehaving, you could provide the clues as to why. The maddening thing is that it all works in HISE, compiled app, and VST, so there is no indication of anything being wrong.

That will help. Comment out all of the includes. Then re-add them one by one until the problem happens.

[gorangrooves]

@d-healey Yes, I'll do that.

[Christoph Hart]

@gorangrooves Hard to say what exactly is causing that but I would scan everything related to repaint() calls or when you start / stop any timers.
