New: FILTER-EVENTS The function FILTER-EVENTS internally brakes-up an omn sequence into single-events (l p v a) and checks whether an event contains the given element. When an element is found the event is returned. All other events are transformed into rests. The option remain will invert the process. (filter-events 'd4 '(e c4 mp -e fermata e. d4 -h e. c4 e e4)) => (-q e. d4 mp -h.s) (filter-events 'd4 '(e c4 mp -e fermata e. d4 -h e. c4 e e4) :remain t) => (e c4 mp -e fermata -he. e. c4 e e4) These two options are useful for orchestration. Examples: (setf mat1 '(e c4 mp arco+ponte -e fermata e. d4 mp tasto -h e. c4 p pizz+ponte e e4 p arco+tasto)) (filter-events 'arco+ponte mat1) => (e c4 mp arco+ponte -we) (filter-events 'arco+ponte mat1 :remain t) => (-e -e fermata e. d4 mp tasto -h e. c4 p pizz+ponte e e4 arco+tasto) (filter-events 'fermata mat1 :remain t) => (e c4 mp arco+ponte - e. d4 tasto -h e. c4 p pizz+ponte e e4 arco+tasto) (filter-events 'fermata mat1) => (-e -e fermata -w) (filter-events 'd4 mat1 :remain t) => (e c4 mp arco+ponte -e fermata -he. e. c4 p pizz+ponte e e4 arco+tasto) (filter-events '(e d4) mat1) => (e c4 mp arco+ponte - e. d4 tasto -he. e e4 p arco+tasto) (filter-events '(e d4) mat1 :remain t) => (-e -e fermata -he. e. c4 p pizz+ponte -e) (setf mat2 '((e c4 mp arco+ponte -e fermata e. d4 mp tasto -h e. c4 p pizz+ponte e e4 p arco+tasto) (e c4 f stacc e. d4 -h e. c4 p ord -e fermata e4 stacc))) (filter-events 'e. mat2 :section 1 :remain t) => ((e c4 mp arco+ponte -e fermata e. d4 mp tasto -h e. c4 p pizz+ponte e e4 p arco+tasto) (e c4 f stacc -h.. -e fermata e4 p stacc)) (filter-events '((e.)

Check the RND-SEED document.

Export the two data files from SPEAR app: Text - Resampled Frames Text - Partials and save them in the ~/Opusmodus/Spectral Data/Data folder. Next: Import the SPEAR frames and partials data into Opusmodus format. Frames: (import-spectral-spear :frames "tbn cs3 frames" ;<- imported file "tbn-cs3-frames") ;<- output file name Partials: (import-spectral-spear :partials "tbn cs3 partials" "tbn-cs3-partials") The last step is to create a library file for an easy access to all the partials. To do that we need to load the file with the LOAD function (the path should point to the file in the Data folder): (load "~/Opusmodus/Spectral Data/Partials/tbn-cs3-partials.opmo") (load "~/Opusmodus/Spectral Data/Partials/tbn-cs3-frames.opmo") or alternatively you can open the file in the Assistant panel and evaluate. And finally we create the library: The expression below will create a folder Partials with inside a library file tbn-cs3-frames.opmo. (create-library 'tbn-cs3-frames 'frames 'p tbn-cs3-frames :file "Partials/tbn-cs3-frames") (create-library 'tbn-cs3-partials 'partials 'p tbn-cs3-partials :file "Partials/tbn-cs3-partials") Having followed the stages as above a new library with the name tbn-cs3-frames.opmo is created in the Def-Library folder.

Update to GEN-CONTROLLER function: The GEN-CONTROLLER function generates controller values in a given span (total length) with a defined time for each of the values (<value> <time>). The count of the sent messages is the sum of the time values equal to the span value. For example span 1/4 with time 1/128 will produce 32 values. (setf values (gen-sine 32 4 1.0)) (gen-controller 1/4 values) => ((64 1/128) (108 1/128) (127 1/128) (108 1/128) (63 1/128) (19 1/128) (0 1/128) (19 1/128) (64 1/128) (108 1/128) (127 1/128) (108 1/128) (64 1/128) (19 1/128) (0 1/128) (19 1/128) (64 1/128) (108 1/128) (127 1/128) (108 1/128) (63 1/128) (19 1/128) (0 1/128) (19 1/128) (64 1/128) (108 1/128) (127 1/128) (108 1/128) (63 1/128) (19 1/128) (0 1/128) (19 1/128)) The :min and :max option allows you to control the minimum and maximum value of the sent messages: (gen-controller 1/4 values :min 20 :max 80) => ((50 1/128) (71 1/128) (80 1/128) (71 1/128) (50 1/128) (29 1/128) (20 1/128) (29 1/128) (50 1/128) (71 1/128) (80 1/128) (71 1/128) (50 1/128) (29 1/128) (20 1/128) (29 1/128) (50 1/128) (71 1/128) (80 1/128) (71 1/128) (50 1/128) (29 1/128) (20 1/128) (29 1/128) (50 1/128) (71 1/128) (80 1/128) (71 1/128) (50 1/128) (29 1/128) (20 1/128) (29 1/128)) If the values count is less than the sum of the time values equal to the span then the last value of the list is used to complete the count.

Just use numbers to pitch, lengths etc... conversion.
