I have a roll up piano (see the image) that has an USB output.

An USB cable comes with it: it is able to connect the roll up piano with the computer.

Is there any way to record MIDI using the roll up piano, the USB cable and the computer (that runs Ubuntu)? Is a MIDI cable really required if I have the USB one?

What are the steps to record MIDI on Ubuntu using the roll up piano and the USB cable?

The output of arecordmidi -l:

# no cable is connected (after fresh restart)
$ arecordmidi -l Port Client name Port name 14:0 Midi Through Midi Through Port-0
# USB only
$ arecordmidi -l Port Client name Port name 14:0 Midi Through Midi Through Port-0 24:0 USB MIDI Interface USB MIDI Interface MIDI 1
# MIDI only
$ arecordmidi -l Port Client name Port name 14:0 Midi Through Midi Through Port-0
# USB & MIDI
$ arecordmidi -l Port Client name Port name 14:0 Midi Through Midi Through Port-0 24:0 USB MIDI Interface USB MIDI Interface MIDI 1

I tried to use QJackCtl and some other applications to make the connections:

The type of program that allows you to record MIDI data is called a sequencer; try Rosegarden, Seq24, or Qtractor.

Your piano can be connected with either the USB cable or a MIDI cable.
