I realize this issue comes up frequently, but I still am unable to record into Logic 8 using the external synth sounds from my Roland x50. I set up a new software instrument track, click i/o, choose external instrument, choose stereo, choose for midi destination the x50 and one of the programs, and choose 1-2 for input. I still don't get any sound (except feedback if I turn the mac volume up). What am I missing? thanks!

why are you choosing a software instrument track? if u just want to record and playback the sounds from the x50 then just use an external midi track and set the channel you wish to use and the midi interface. If you want logic effects on the x50 sounds then choose a software ins track and insert the external instrument plug in as an insert. In this you set the midi interface ur using and the audio track that it will send out to. there are plenty of you tube videos on this.
