Posted February 15, 20241 yr Additional DICTUM types: :grace-note and :previous Executes a specified function applied exclusively to grace note events. (:do (pitch-transpose 12 x) :grace-note t) Executes a specified function within the specified bar(s) exclusively to grace note events. (:do (pitch-transpose 12 x) :grace-note t :bar 2) This operation alters elements meeting certain predefined conditions from the preceding event, replacing them in the current event with a new element. Such conditional manipulation facilitates intricate, criteria-driven modifications. (:previous ff :do p) (:previous (h c4 f) :do (pp tr)) Example: (setf omn7 '((s fs3 mf d4 a4 c5 b4 f4 bb3 cs3) ((acc e f2 cs2) q c2 f stacc) (s e2 b2 gs3 e4 bb4 c5 bb4 e4) ((acc e gs3 b2) q e2 f stacc) (s c2 cs2 f2 cs3 bb3 f4 b4 c5))) (dictum '(:previous c5 :do (cs6 tr1+fermata)) omn7) => ((s fs3 mf d4 a4 c5 cs6 tr1+fermata f4 bb3 cs3) ((acc e f2 mf cs2) q c2 f stacc) (s e2 mf b2 gs3 e4 bb4 c5 cs6 tr1+fermata e4) ((acc e gs3 mf b2) q e2 f stacc) (s c2 mf cs2 f2 cs3 bb3 f4 b4 c5))
