sxformat Format a system-exclusive MIDI message using expr sxformat can make it easier to send system-exclusive parameter change messages. It takes as arguments a list of numbers which are sent out sequentially. In addition, you may use one or more "expr"-style statements, which start with the word "is", which will be evaluated, with the result being sent out. "is" statements need to be separated by slashes. The format of sxformat arguments is similar to statements in a "lib" object script.
