I want to send program change msgs to my Yamaha P-60 in CM. The P-60 does this with a combination of a program change msgs and a bank select/control change msg. Is there a (make-control-change ...)? Are the (make-...) midi msg constructors documented anywhere? The dictionary doesn't seem to mention them. Chapter 21 of Notes From the Metalevel mentions a few of them, but not in detail.
