Could be one of a thousand things, but try some of these- This may be too obvious, but under "Audio-->Audio Hardware and Drivers" make sure the 828mkII is selected in the pop-up menu in the CoreAudio driver... make sure the piano track isn't muted in the arrange window AND the channel isn't muted in the mixer window. (also make sure channel 1 isn't muted) Make sure the output of the track is routed in the mixer channel strip to the standard output going to your 828mkII (Output 1-2 or whatever your 828 says). When you play back your MIDI part, watch the meter on your 828mkII -if nothing is appearing in the meter, then there's something in Logic that needs to be changed - if you're getting a meter signal but no sound, you might check your amp and monitors, etc. GK
