I have never seen MIDI output using Running Status from any device I owned.Have you investigated this at the protocol level? Running status is intended to reduce the amount of information that travels "over the wire," but by the time your application receives the MIDI messages they are fully formed. In other words, it's not something that applications need to take into account except when reading (and optionally writing) MIDI files.

Do such devices exist at all?
Can any regular MIDI keyboard be configured to turn the Running Status on/off?
Need to do some testing for a software issue: https://github.com/jazz-soft/JZZ/issues/26
Thanks a lot!
