seriose lisp programming

How/what libs?
Mainly sockets and SDL stuff.
Please tell me i can use these in scheme. I don't want to read steeles book on common lisp it's huge ;_;
currently i am using MIT/scheme.

Real Scheme code. Note the hilarious hack and the manually passed random state.
(map (lambda x
           (let ((idx (random 12 random-state)))
            (make-music 'EventChord
             'elements (list (make-music 'NoteEvent
                              'duration (ly:make-duration 2 0 1 1)
                              'pitch (ly:make-pitch (quotient idx 7)
                                      (remainder idx 7)
                                      0))))))
       (make-list 32)))))
How it would look in CL. Notice the improvement in every way.
(loop
  for i below 32
  for note = (random 12)
  for octave = (truncate note 7)
  for class = (mod note 7)
  collect (make-music
           'EventChord
           'elements
           (list
            (make-music
             'NoteEvent
             'duration (ly:make-duration 2 0 1 1)
             'pitch (ly:make-pitch octave class 0)))))
