Design Choices @andee_marks

Design Choices #1/Notes ⇨ <module name="LineLength"> (cond (< line-length 10) (note-from-octave octave-1 line-length) (<= 10 line-length 39) Notes (note-from-octave octave-2 line-length) (<= 40 line-length 79) (note-from-octave octave-3 line-length) ... @andee_marks

Design Choices #2/Tempo ⇨ <module name="CyclomaticComplexity"> (+ (* 20 complexity) default-tempo) Tempo @andee_marks

Design Choices #3/Key ⇨ <module name="SimianCheck"> Keys (if (< duplication-percentage 10) (set-major-key) (set-minor-key))) @andee_marks

Design Choices #4/Instruments ⇨ (if (not (= current-author (get-author))) (instrument-for current-author) Instruments @andee_marks

Design Choices #5/Lyrics (if (not (= current-source-file (get-source-file))) (lyrics-for current-source-file) Lyrics @andee_marks

Design Choices #6/Sequencing Sequencing @andee_marks

Design Choices/Unresolved ⇨ Volume Stereo Length /** **/ Editor Note length Comments integration @andee_marks
