Thank you for your time.

I'll be back home later, than I'll try w/o -S option.

I think the synth is listening : I set up Jack Keyboard to the same channel
on the synth. And what really worries me about is the fact of USB Interface
not blinking the MIDI output status light. So it seems the interface is not
receiving any data from the computer.

A few days ago I connected the same USB interface to my Smartphone (Android
6). I installed a simple MIDI program and the synth received the messages.
Man, I'm so sad about it, because my band has some shows scheduled and I
was coding something, based on Jack Keyboard source code, to send SysEx
messages to the synth, to make the performance even easier.
