...so unless you experience such a problem, it might not be important.

when using the editor (stand-alone or within studio manager using the USB cable), how can I do to play the rack? I mean, is it possible to connect the extarnal keyboard in some way to listen to the loaded sounds, or edited sounds?

See MIDI channels and MIDI ports, specifically the Port 3 information, on page 18 of the Owner’s Manual. With MIDI In/Out set to USB, data from a MIDI controller connected to the Rack’s MIDI-In will transmit on Port 3. Any software that allows rerouting of that Port 3 data to Port 1 should work.

From one of my posts in a previous thread…

I downloaded and installed the Rack XS Editor. I don’t have a Rack XS, but the Editor didn’t care (for port setup purposes, not editing). I was able to configure the ports so that an external keyboard (connected to my XF’s 5-pin MIDI-In) is able to play the XF while it’s in USB MIDI mode with the Editor running. You should be able to do the same with the Rack.

I suggest that you read Readme_MIDIPort_Editor_EN.pdf
It comes with the Editor download.

This should work…
Click Setup under “File”
On the Setup screen, USB and Detail On
Set MIDI KB In to MOTIF-R XS-3 (Port 3)
Set Port 1 - MIDI Out to MOTIF-R XS-1 (Port 1)
Set Port 4 MIDI In and MIDI Out both to MOTIF-R XS-4
Click OK
Turn Thru on at the lower right of the main screen

Let us know if you need further help in setting up the ports.

The above is based on the 1.6.3 version of the Editor, running stand-alone.
