Here is where you can change the parameter values for the selected event. The labels will reflect which event you have chosen.
List of of MIDI events in the selected track.
NOTE that a MIDI note always comprise of two events, the “note on” event and the “note off” event. SynthFont tries to connect the right pairs, but sometimes this is not possible if there are several notes of the same value overlapping.
Surplus events are events that do not change the current value of the parameter.
Event filter: select here which kind of events to show. Note that here proper Controller events are separated from self-contained events like Program Change
If you are a MIDI expert you may be interested to learn to use the events list editor. There are only a limited number of editing features: you can change the timing of an event (“When”), the type of the event (if it is a Controller) or the note value for a note, the Value of the Controller (or velocity “Vel” for a note) and the length of a note.
