Topic: RME Digicheck 5.81 Real Time Peak spikes in Cubase VST Performance.
I noticed strange spikes on the real time peak meter of the Cubase 8.5.15 VST Performance with no project loaded. The spikes can reach the limit while the CPU meter is at 2% and lead to audio crackles with a project loaded.
I spent a day to find the culprit (changed settings in BIOS, ...) and it is the Digicheck process.
"RME's sophisticated tool DIGICheck operates like an ASIO host, using a special technique to access playback channels directly." "DIGICheck 5.81 operates as multi-client ASIO host, therefore can be used in parallel to any software, with both inputs and outputs"
"DIGICheck DSP: Level meter in hardware, peak- and RMS calculation". But not for Totalyser which use ASIO and is very important in my workflow.
I found these Cubase VST Best Settings
• Multi Processing activated;
• ASIO Guard Normal activated;
• Steinberg Audio Power Scheme activated.
I noticed that the spikes disappeared when I deactivate Multi Processing. But this is not an option to use only one core of a 1000$ 8x2 cores CPU.
Notes: The spikes are manageable with latency greater or equal to 512 samples and level meters set to hardware.
I can't do further testings because it is beyond my skills.
I chose RME for the quality of the driver which are constantly maintained (I have a Multiface, RME9652 and choose the Babyface Pro to wait for the UFX+).
But also for Digicheck which is an important part in my workflow and because I thought it had no impact on the ASIO performance as it is hardware DSP compute. This is not the case.
So my questions are:
Did you notice this misbehavior?
Do you have recommended settings?
Do you have an update planned to use Digicheck's "special technique" with Multi Processing?
