Hi, I’m on macOS 10.15.5 here and experiencing an extremely troublesome issue with Live 10.1.15 and Neural DSP Archetype plugins.
I’m running a mid-2015 MacBook Retina Pro so nothing amazing but there’s 16GB of RAM and a 2.5 GHz Quad-Core Intel Core i7 processor in there so I’m certainly not underpowered here. My system is a fairly fresh install of Catalina and is running pretty lean generally.
So, when an amp sim plugin is first instantiated on an audio channel in Live (and this is alone) the CPU meter clocks between 16-21% - this is in Normal mode; obviously it would be a bit higher in Oversampling mode…about 29-35%. I understand this is a single-core reference. As time passes the CPU meter creeps up…it does this over minutes until it hits anywhere from 80-115+% and sometimes even crashes Live. Digital garbage commences around 75-80% and it become unusable. Deactivating the post FX will slightly lower the number but doesn’t really help much.
Im operating at 48kHz and my buffer is at 128 though I’ve tried all possible buffers with no success.
Sometimes the plugins come back to normal CPU range. Sometimes they just stay high and crackly.
The only other plugin in my system that behaves like this is another Amp Sim/Fx plugins: Blue Cat Audio Axiom. The behavior is almost identical. For comparison, Helix Native sits and behaves at around 16-20% all the time.
I’m really not sure if this is a Live issue or a plugin issue but would appreciate any advice you may be able to offer. I’ve not been working with these plugins much recently so it’s hard to say this with 100% conviction but I do not remember this kind of behavior ever since day one of the Plini plugin. Since I don’t remember these plugins ever being this unreliable there’s a good chance it may be a problem with Live 10.
It seems to happen with AU, VST2 and VST3 versions equally.
Hope someone here might have some useful advice or a definitive solution to this problem. Thanks.
