request: Plugin in AU format

[gdreyband]

Hey @jpcima I'm so glad I found this! I was an occasional contributor to JUCEOPLVSTi and I'm so glad to see an OPL3 plugin that's available on Mac natively! I'm playing around with the standalone version now but I'm a Logic user and I'd love to see AU plugin formats supported.

Let me know if that's possible.

Hello @gdreyband
This project is based on Juce plugin framework, which means the code should support directly the Audio Unit specification.

It's not yet readily available only for a few practical reasons.

1. I'm not an owner of Mac, meaning it's difficult to test things personally, and I rely on external feedback which I receive.
2. It's been low on the priority list, because now one has requested it before you did.
3. Last time I looked, I did not understand how to introduce this to automatic builds, because the AU way if building has confused me; but I will re-examine this.

As a user of Mac, you have a solution to construct AU which has a possibility to work, if you are adventurous enough to build the source code.
These subdirectories contain Xcode projects, which hopefully are able to build.

• project/adl/juce/Builds/MacOSX
• project/opn/juce/Builds/MacOSX

I cannot guarantee this method succeeds, because I have never tried it.

@gdreyband I have some AU builds under the latest dev release.
Are they working?

[gdreyband]

I just tested the one under latest, I got an incompatible plug-in error so it doesn't work unfortunately. I can try to do a build of the source over the next few days.

I have made a new iteration of Audio Unit. You're welcome to try this one.
If still not working, please indicate the computer model, OS version, and processor architecture.

• fixed a defect of AU bundle construction, where the resource fork is not at the right location
• the Xcode project files have been updated
• symbolic links have been added in the package (for a more dmg-like experience, but not quite still). I should provide a DS_Store layout
• files remain distributed as 7z; I have thought of changing it to something more conventional, like a dmg or xip, however 7z is compressed twice more compact.

@sub26nico if you have time and opportunity for this, do you mind to try loading these Audio Units ?
It will be very appreciated.

Binaries are found at the usual place.

For reference, I'm on a Mac on OS 10.12.6, using Logic Pro X 10.4.4

It works, although it fails the plug-in check. If I override that I can use it within Logic.

There are some miscellaneous bugs I found which I can file separately:

For both AU and Standalone

• In the bank [AIL] Ultimate Soccer Manager, certain patches just produce a generic white noise sweep. They're 2-OP and they all appear to have the same or very similar parameters. Switching from FM 1-2 to AM 1-2 produces a vacuum-like noise that doesn't decay.
  Patches, for reference: 29-31, 44, 50-55, 65-67

@jpcima , I've quickly tested the binaries, all seems good. Standalone works fine and made sounds.
Au,Vst and Vst3 works in Reaper, Au,VST and lv2 works in Ardour. I have just put the plugins on a midi track and play with the keyboard on the UIs, no more. I'm on El Capitan (10.11). I have no much times at the moment but feel free to ping me later if you want deeper tests.

Yes. The plugin has a known defect ; it is unable to handle adequately parameters and states while it is in a disabled situation. It was an oversight of the design, and is most likely why validation is not passing.

With a somewhat hackish workaround used, it seemed to operate fine in practical cases.
An ideal solution takes some work and more rigorous testing.

It's the original game bank and most likely it never used these instrument slots.
About noise that doesn't decay, you are correct, and more annoyingly the panic button is not able to silence these channels.
@Wohlstand this seems like a case where adl_panic is failing.

@sub26nico
Thanks also for confirming AU working.
I have managed a vmware setup which gives me access to compiling and AU lab, but none of the big DAWs though.

Looks like is need to override instruments by correct zeroing data, and also be careful against rhythm-mode which makes three channels to act differently... Will check this at my home, for now I'm at my friend
