Im having some problems using the external FX in paralell in Cubase Pro 11. I recently started Cubase so im in a middle of some testing for my work.
One workflow i use a lot is paralell processing.
When i try to use an external compressor on a duplicate track i get some comb filtering, sounding like the compensation is not working properly like it should.
Here is the process:
Track 1 - Audio
Track 2 - Copy of same audio but using the external FX inserted ( i setup all properlly in the connections so i know its all well routed, i see some signal in the compressor and on the way back in). After i insert the plugin on channel 2 i ping the plugin gives me 0 .0ms but i have comb filtering.
Same doesn´t happen in Reaper , my other daw ( using the insert plugin - which compensates for roundtrip plus the audio interface buffer size latency)
The only method i found is to render the audio and import it back in to the session.
