I have been playing with Renoise for the last weeks, I think I have understood all the basic stuff (I used in the past Reason), and I’ve started some nice project songs
yeah sounds like 2 layers to me
bottom layer sounds like a low pass saw wave
top layer sounds is 1 octave above and has more harmonics. again a sounds like a filtered saw but with chorus/detuning with an maybe an amp sim for color.
there is small room reverb in there, maybe with some modulation on that too
