The AURA Editor works quite nice for me, really.
The cumbersomeness goes away when you use a midi interface that can merge MIDI signals internally.
I use a MioXM and I can merge the data stream of the Editor and my Keyboard very convenient.
I always had hickups with the original software even if not using the audio side of things.
Plain midi editor use caused glitches on the audio (not USB audio mind you).
The AURA editor really cured that and gives me good tool to have (kind of) total recall.
The developer is kind and very responsive.
It´s a bit of work to setup the thing and confusion arises IMHO mostly when using midi-loop-back to merge virtually on your computer.
Ins become Out....
This is a shortcoming of windows of course not the editor itself and is due to the restriction to one client per physical Midi-I/O on Windows (even 11).
This is the reason why Access implemented a 2nd Midi device in the driver for the Virus TI one for playing, one for the editor....never really worked sadly.
On Mac multiclient use of Midi devices is possible (don´t know myself really because I am on Win11).
