Approach

  • Uses mid2seq to extract notes from existing MIDI files
  • Tick-based notation preserves original timing and velocities
  • Patch 19 = Church Organ (General MIDI)
  • Chord notation [A4,A5,A6] for simultaneous notes
  • Pipeline: mid2seq → seq → to-midi → fluidsynth

Bach-esque - Algorithmic Baroque

Abstract
Procedurally generated baroque-style organ music. Three voices generated algorithmically with seed 1685 (Bach's birth year).

Approach

  • seed stage provides deterministic randomness
  • motif stage generates melodic patterns algorithmically
  • scale stage quantizes to D minor scale
  • Complexity 9 = high melodic variation for upper voice
  • Complexity 2 = simple, stable bass foundation
  • Each voice uses different seed offset for variety

Hard Rock - Arensky Inverted & Reversed

Abstract
Anton Arensky's String Quartet No. 2 in A minor (1894), with voices INVERTED around A4 and played REVERSED. Arensky (1861-1906) was a contemporary of Tchaikovsky but far more obscure. Transformed into aggressive hard rock with funky syncopation at 150 BPM.
