"""
Thanks for your reply Lenard,
I looked at the examples and created this working program (see program
below). When I close the program, this error message appears in the
terminal:
PortMidi call failed...
PortMidi: `Bad pointer'
type ENTER...
What can I change in the program to avoid the
"PortMidi-call-failed-Bad-pointer" error? Any code snippets, links to
articles, or suggestions would be greatly appreciated.
