Lessons learnt from this session.

(a) instead of teaching a synth to handle both mono and stere buffers,
    you could write a function which loads sound into stereo, duplicating
    the mono if needed

(b) it's not very convoluted to load all sounds in a folder into a
    dictionary, indexed by the filenames..

    (filename:buffer-with-sound-from-that-file,...)

(c) [["foo",12],["bar",42]].flat -> [ f, o, o, 12, b, a, r, 42 ]
