Hi I'm new to the forum,any help would be greatly appreciated. I'm running pro tools 7 on a mac G5 with mbox 2 pro. I have a TC HELICON & Lexicon MK200 that i would like to use to add effects to vocal tracks. I tried using the MK200 on a mono vocal track. Connected the spdif from mbox to MK200,created new mono track,set output of vocal track to spdif L and input of new mono track to spdif L. The meter on the MK200 shows a signal but no signal on the new track i created in pro tools. My goal was to have the effects on the new track so i could blend them with the original vocal track.
