It seems that S3 has lost the option to D&D a MIDI over the window, so there is no other way to recognize a midi than playing it on another track, YUK
I hope this feature is in the standalone (that I don’t use)
Otherwise, this lacking feature is a problem
Wait that I found it: not a D&D but you have to click on the almost invisible folder icon
The problem is that having one only a “Save icon” for uploading a file is counter-intuitive, and the tooltip doesn’t work in the Detect Midi area
then you can select a MIDI in your PC
