i forgot to mention that i do drone music myself from time to time.
(sorry, i´ve got no recordings, i do that just for fun…)
one typical setup would be: a “simple looping device” a guitar and/or a mic, a simple mixing desk, a distortion pedal, spring reverb, bit crusher, etc…connect that somehow, create a drone kind of loop and then start to create feedbacks with the mixing desk and play around with all the knobs…
tried doing that kind of music with the OctaTrack too but i prefer doing it without it
