But i'm surprised at your comments - maybe I've got this wrong, but it seems like you are saying your interface already had a -10 setting, which you could drive to 0 directly with your keyboards? So why do you want a Line Level Shifter again?

By setting your interface to receive a +4 input, you have added 12dB of headroom. I'm wondering if you have the LLS around the wrong way? Being a passive transformer, it will pass signal both ways, but obviously will work as an attenuator if used backwards. I plan to test this feature as a stereo reamp option.
I definitely have TRS cables on the +4 jacks running to the interfaces - checked that. I wanted the shifter because I'll be upgrading my interfaces to units that only run at +4 and I didn't want to spend for a bunch of preamps or a mixer. I also checked the labeling by swapping cables, which attenuated the signal (as expected) so the labels are correct. Even though the meters are reading low, the volume for a couple machines is acceptable though not great. The one that really suffers though is the Future Retro 777 - far too quiet. I'll just run that one through one of the Pacifica DI jacks - that works quite well
