I recently left Cakewalk Sonar for Cubase SX and I am loving it; however, I have one regret. Cubase's sheet music interface is horrible. I love the interface that Sonar provides and wish that I could control Cubase with Sonar, i.e., use Sonar as a sequencer to control my software synths and samplers that are running as VST in Cubase. I have only one MIDI port on my system. I realize that for win9.x there is a program called Hubi's Loopback Device that would solve a problem like this, but this utility does not run under Windows XP, which I use. If anyone knows of a way I could accomplish this, please let me know. Thanks.
