3 years ago Hi,
Try the following... put a sleep(1.0) (more, or less) between the two statements, and see if that helps...
Explanation: The first statement uses the JVM Midi sequencer, which runs in a separate thread inside the JVM. The second statement is executed far too soon (i.e., before the Java Sequencer had a chance to finish opening the MIDI file). Adding a little delay should take care of things. Also, you might want to download the latest code from http://jythonmusic.org. This github code may be a little outdated. But that shouldn't be your problem.
