And assumed the data flow should cause that much traffic for a single MIDI interface, that e.g. note offs get lost? I just ask, since the OP mentions missing note-off events. It's idiotic to use old school MIDI by trying to expand it, while it already didn't provide the ability with old school non-multi-tasking-direct-midi-hardware-access-but-absolutely-hard-real-time computers to do things like that. Nowadays computer design by nature can't provide this in a sane way. Resp. it might be possible by using several MIDI IOs for such a task, but it's at least risky, when using a single MIDI interface. JFTR not all MIDI interfaces are using the same chips and/or diodes to provide edge steepness, sometimes adjusting a potentiometer could do magic.
