It happens because of the Java source code that is inside MidiDriver2.jar. @stevel05 needs to remove those.

 

[stevel05]

I have removed the source from the MidiDriver zip and updated the MidiPiano project. It was one I hadn't tested lately. @Theera. thanks for the report. Please download both again.

@Erel, it's strange that the driver worked with the source included in other projects.

@Erel, it's strange that the driver worked with the source included in other projects.

This is the first time that I encounter such issue. Might be related to the updated build tools.
