Pro Q-3- Issue with Audio Units in Ableton on Mac

I am using the AU version of Pro Q-3 on a session in Ableton 10 (as the AU version works with Instance naming, and VST2 doesn't), and I am finding that every time I open Pro Q-3, and add/edit an EQ curve, the spinning wheel appears and stays spinning for 20-30 seconds before I can use Pro Q-3 again. After that it is okay. But if I open a new instance of Pro Q-3 (say on another track), it happens every time.

This is 100% reproducible on my current Ableton project (around 20 audio/midi tracks). I have a new Mac Mini 2018 (Core i7, 32GB Ram, 512GB SSD) running Mojave, so not a slow machine.

Is this a known issue?

Just to add that this issue does not occur when using the VST2 version of Pro Q-3.

Thanks Frederic. If you need any further information from me on this issue, or even any screen recording, let me know.

Hi Frederic,
Any update on this?

Even on a new small project I have just started, using Audio Units is not viable. This bug appears every time.

I have to use VST2 in Ableton, as they do not support VST3, and this means that Instance naming does not work correctly, making my workflow much more difficult to manage.

I would much rather use the Audio Units, where Instance naming works, but this bug gets in the way.

Thanks.

Hi pramster,

We're looking into this! We've tested on Mojave with the latest Ableton Live 10, but haven't been able to reproduce this issue yet...

Does it only happen when adding a new curve, or also when editting an existing one? Does is happen only when using many instances, or also with the first or second instance?

Thanks,
