I recently upgraded from Cubase Pro 5.5.3 to 10.5.20 and noticed in the mixer that there’s a constant low noise/signal on every input channel regardless of whether I have anything physically connected to my audio interface’s inputs or have added any tracks to a project at all.
I can open the same project (or create empty ones) in 5.5.3 and do not have this issue. If I open existing CB 5 projects or create new, empty ones in 10.5.20 all the meters are showing a slight signal coming in.
- I removed ALL connections to my 8 ch audio interface (Tascam FW-1884), turned all mic pres to 0, and all input faders to 0 but still see a signal coming in.
- I tested switching audio interfaces to the ASIO DirectX Full Duplex & then again to the Generic Low Latency ASIO driver and still the signal is there so I am doubting it is the interface.
- I tried changing my buffer per another similar post but that didn’t help (https://www.steinberg.net/forums/viewtopic.php?f=226&t=128048)
- I tried recording input channels 1-8 from the audio interface (with no actual audio sources plugged in) and a signal DOES record in ver 10.5.20 so there’s definitely some slight noise/interference there.
- Similarly I tried recording inputs 1-8 in Cubase 5.5.3 just in case there actually was noise even though the meters showed no activity, but nothing recorded–not even silence. Cubase 5 saw no input and thus no audio files were created proving the mysterious signal isn’t happening in ver 5.
Because it does not happen in Cubase 5 on the same PC with the same audio interface, I am wondering if it may be a Cubase 10 setting or feature I am unaware of. Although I’ve been reading the CB 10 manual and trying to learn all the changes/features, it’s a steep jump from 5 to 10 and I don’t see anything that stands out to me.
Can anyone shed some light on what may be causing this or how else to troubleshoot?
FWIW, my issue seems similar to these other posts:
