I know it's been awhile since this thread was started but I just noticed it, at a time when I just made the switch from MC5 to Sonar 8.5.2 and I've been using the UA-4FX for a year now. I've been quite happy with its performance but only recently have I tried to move it beyond its 44.1khz sampling setting and attempt to use the 96Mhz settings.
First, why does it have a separate switch setting for record(r) and playback(p), for 96khz sampling? Do they really expect us to flip a switch to one or the other each time we record a track and then try to play it back? We didn't need that in 44.1 or 48 settings! The manual says nothing about how this setting is to work. Further, I have not been ABLE to get it to work. MC5 seems to have only as high as a 48Khz sampling rate - the drop-down in the sampling rate screen only goes to 48. Sonar goes all the way up, but when I try to set the Edirol to 96 on either setting, restart either by unplug/plug in the USB, or power cycle the whole PC and box, Sonar loses the Edirol setting altogether and sees no interface. Can anyone verify the usability of the 96Khz sampling setting with this unit? Thanks!
