firestARTerjust released a new version of the GP2x Midi Interface for the LittlePiggyTracker. In the new version it is possible to use all Midi-Commandos now. So LGPT can be used as a little Handheld Midi-Sequencer. If someone like to add Midi to her/his Application, it is no problem with the GP2x-Midi Interface.
