I have a mixer but wanted to have a headphone out on the rack to not need to power everything on to just have a play with the synth. I know that envisioning this whole rack as a stereo channel being labeled as 'mod synth' on my console next to 'Lead Vox' or 'Bass G' is already probably flawed thinking in the long run :-)

I could just get a small Mackie mixer or the like and run the mix out from that into the main desk.
Doesn't modular run a bit too hot for a normal line level mixer?

The CVilization seems really cool. Mode one (4x4 matrix mixer) and mode two (4x4 sequential switch) particularly so.
Thank you again for the steer to look at matrix mixers as I would have probably not looked into this functionality as deeply before.
If i find one of these modes invaluable then I could always get a dedicated module for that next. What is super cool about the Cvilization is that in either mode quantisation is an independent and additional function that can then be added to any output individually! And best of all does all this in 10hp!!
