Thanks a whole lot for the response.  I had this weird phenomenom when I
used audio 1 in logic and added waves rverb and hit notes on the keyboard.
The reverb wasn't as strong as the reverb with the onboard fx.  I had to
turn down the channel volume in logic for that channel or the waves
plugin's level would shoot up to the top and max out and distort like
crazy!  Do you know what this is??  Any help would be very much
appreciated.  Thanks again.
