thanks for the info, Greg and Guitarhacker.
I think I will upgrade to MC6 and keep my fingers crossed.
I don't use Finale or Sibelius because I find them clumsy and stiff compared to Cakewalk; I have used Cakewalk since 1998 and love it for scoring. I arrange A Cappella for my work and this program offers so much.
Sound card is Roland Edirol. I know nothing about the tech stuff; this was all on the advise of a Computer God. How do I figure out the sound card settings, synth setup and routing? I'm horrifyingly ignorant of this stuff.
Greg, in response to your confusion about transferring tracks, I probably used the wrong word to describe what I'm doing; I assign an output to the tracks.
I'll get MC6 running and report back.
thank you both for your assistance!
