I don't know if there's such a tool. But AFAIK jack would only block
the raw MIDI device when you use "-X raw" to use the raw MIDI driver in
jack. Do you need that driver? If you don't, you can use the "seq"
driver instead. I find that one more useful anyway. You can change that
in Setup -> Settings in qjackctl. (Also, checking "Enable client/port
aliases" in Setup -> Display shows you readable MIDI device names in
the qjackctl MIDI tab, instead of the useless JACK default names.)
