I'm listening to an ambient track by ILDJARN that sounds like it's coming out of the same synth as B12 – and so I think of B12.

Axiom: the choice of a synthesizer rather than another is more than a choice of material, it is even more than the choice of a style of music. It is also the choice of the whole era in which it was produced and of all that was done with this material, and that its sounds will evoke by association of ideas.
