Hi @Lugia , thanks for the suggestion, I'll think about it.
I'd like to note my workflow to audio path, usually I make a hard use of stereo path, is for this reason I have 2 veils (for the moment I don't find another solution). I use one veils for left channel and the another for right channel. Sometimes I use HPO as a merger stereo, sometimes I use an external mixer. When I make a recording session I use each out from veils to sending the audio to external mixer. I've spent a while searching a solutions mixer to keep the stereo path in eurorack, and save hp as possible... but I didn't find nothing better, so I continue with this workflow.
Because I'm working with hard stereo path, mostly I use the buffered multi (links too, so useful for those works) as a mixer/splitter/merger the audio path. Sometimes I make a hard use of that, sometimes less. Maybe I should replace the buff mult from wmd to another links better for this kind of audio works.
