So first off, Cantabile is definitely my lifesaver regarding these off/on broadway shows, and it gives me a very good reason not to get a Mac for Mainstage.
I run my Keyboard (Roland Juno DS88) to Cantabile, which is usually running Keyscape for great keyboards, Kontakt, Roland Cloud, and Hammond B-3 X from IK Multimedia. Sometimes if I don’t like the sounds I have from the program, I usually have my own performance set on my Keyboard, and Cantabile routes the midi data back to my keyboard to a specific channel that I choose to play (I don’t have a timpani patch on my computer? No worries. Route it back to my Keyboard!).
I also have a Behringer FCB 1010 foot pedal. I found so much use for this for turning pages using Cantabile and go to the next state of the song (yes, I have Cantabile Performer).
I tend to have the best quality possible when performing these shows. Thanks to Cantabile, it makes it much easier to program without putting my hands off my keyboard.
Edit: If you want to see my setup for these shows, I’ll post one below for you guys!
