Ok thanks

I have a track with the TTS-1 and whenever I press a key in the piano roll the green vertical bar moves but no sound whatsoever, no idea where else to check Also I'm following a tutorial video (https://www.youtube.com/watch?v=_2izQxY_x3Q) but not even the metronome is emitting sound.

Is it posible to play midi tracks without a device? I created a midi track, placed some notes but there is no sound, so I guess I need a midi driver. If I go to Prefereces > MIDI > Devices there is nothing there. Any help? Basically, all I want is to be able to create a MIDI file by placing notes in the piano roll and choosing an instrument for it.
