I'm just getting started with Logic Express 7 and I'm trying to get my keyboards to work with the program. I went through the tutorial "getting to know the invironment" about setting up multi instruments but to no avail. I got the Quicktime synth to work for awhile, but even that didn't sound the last time that I selected it on my arrangement window. I'm getting MIDI signal, but no sound. I went back through the tutorial a couple of times, but I can't find what I'm missing. Any help would be greatly appreciated, thanks!
