Hi, I’m using Ardour. In the specific case I used a two-channel stereo track.

The purpose is to use a track of 12 monophonic(!) channels (with Ardour you can do it). For example I load 6 parallel VST instances of the Eiosis AirEQ or equivalently with 2  5.1(= 6 channels) VST instances.

In the specific case I will have to use six VST instances of Blackhole.
