I am working with a student who is just getting started. She is a good musician. I recommended Cakewalk by Bandlab. The price was right and I have used Sonar since Sonar 1.
On her (first DAW) download,I have not found any other VST instrument except TTS1 and the general midi sounds. Am I missing something?
