The plug-ins open with no problem, but when you turn the knobs, change presets, or whatever you want to do, the GUI shows you no change at all.
For example, if I move the cutoff knob from a synth, it will affect the sound, but you can’t SEE that movement in the knob. It looks like a problem with the GUI.
It’s happening with U-he, PSP, SoundToys and Antares plug-ins.
I see, thank you. Definitely not the same issue and surely GUI / GPU related.
I’ll have a look as soon as possible, but I can tell you that it’s not a general issue - would you please PM me your Mac specs (a zipped system report would be even better)?
By the way, those plug-ins were working fine on Cubase 5 (32-bit) running on Snow Leopard (10.6.8).
The problem started when I updated the OS to Mavericks. Then I had the same problem in Cubase 7.5 (32-bit) and now in Cubase 8 (64-bit but using Jbdrigem to run 32 but plug-ins)
It looks like this is just a CUBASE issue, since all of those VST are working perfectly in Live 9 also on Mavericks.
Frankly, a comparison can’t be done between Cubase 8 and 5 (or other applications coded on different frameworks).
Not only the OS is completely different, Cubase itself is now built much differently. Most of the GUI / GPU related issues are system specific, which is why the plug-ins behave differently from system to system - I’m honestly surprised that PSP plugs are doing this for you, I’ve seen those working fine on a huge amount of Mavericks systems, I can’t remember seeing this before, although I’ve see it with other vendors.
You could try also to avoid bridging, I’ve seen a rush of issues with bridges on both Win and Mac recently.
But it’s worth a deeper look.
A quick follow-up: I just checked here on a Mavericks MiniMac (some PSP and Diva demo) - the knobs react as expected on a small test project. I’ll wait for the system report, thank you!
unfortunately not. The system logs are basically empty, only showing a very common warning on the use of a font.
Did the trouble-shooting article I sent you make any difference?
I did check my backlogs here and I found two very similar cases, both users on a Mac with the same GPU you are using… it looks like that is quite likely the culprit. I’ll try to gather some more info about this.
