Changes in version 0.10u:
- Added support for legato where a controller value is set instead of sending the NOTE_OFF of the current note after the NOTE_ON for the next node. This is needed for certain MIDI devices (e.g. from Roland) to enable usage of note slides. This feature can be enabled by setting the attributes "legatoController", "legatoControllerValueOn" and "legatoControllerValueOff" in the MidiPlayer's "map" tag.
