I'm having a problem with my mbox and tc electronic m one effects processor working together via spdif. The only way i can get them to work is setting the clock source on the mbox to the spdif setting instead of internal. I shouldn't have to do this because the m one should be able to work off of the mbox clock. in the m one i/o menu you can select either analog, or digital. and under digital you can select 44.1, 48, or digital. when i select "48khz" i have to use the m one's clock. when you select "digital" the m one is supposed to lock to the incoming clock source but it's not for some reason. any suggestions?
