TODO¶

1. Check that polyphonic context works;
2. Ensure that program change messages work;
3. Ensure key presses work. (Niels: Buttons now sometimes turn red when you click on them. But this does not seem to happen consistently; i.e. most of the time no response is given; this might confuse participants when it suddenly works and then doesn't);
4a. Ensure that ratings and reaction times are recorded;
4b. Ensure that responses are recorded after the end of the melody;
5. Check why some chords (particularly the first one in each cadence) are played twice inside the programme. This is not the case when played outside the programme; thus, it should not be a problem with the MIDI files themselves, but a problem with the programme's interpretation of the MIDI files. This does not seem to occur when Marcus runs the programme on his laptop;
6. Investigate why MIDI files are played inside the programme with a lot of reverb even though this reverb is not present when MIDI files are played outside the programme. I have tried changing the <midi device> argument, but it doesn't seem to make any difference;

Other points:

1. Check that probes are activated at the correct note;
