Thanks for the answer! I'am not asking for a release date, practising paitience in the mean time :–)

I'am strongly interested in a C-Sound-like environment in OM! The example above is not working yet, right? Is it possible to load the CLM package myself into OM (to follow the tutorial on the CLM Page)? If yes, how, can you give a brief instruction? Thanks!

how did you found it, it's not documented..? And it works only for binary lists, right?

Thank you!

Hi André Just investigating your function.. Then I've tried a little cosmetic hack to make it more readable, but it did not work out and I don't understand why. What did I overlook? Thanks! ole ;;; the orginal function (defun binary-filter (alist bin-list) (let ((event-list (cond ((omn-formp alist) (single-events alist)) (t alist)))) (flatten (loop for i in event-list for j in bin-list when (= j 1) collect i else append (cond ((omn-formp i) (list (length-invert (car i)))) ((lengthp i) (neg! (omn :length (list i))))))))) (binary-filter '(q c4 mf d4 e4 e f4 ppp g4 a4 b4) '(1 0 1 1 0 1 1)) => (q c4 mf -1/4 q e4 mf e f4 ppp -1/8 e a4 ppp e b4 ppp) ;;;Why is it not working?? (defun foo-rep (n sequence &key omn) (maybe-omn-decode omn (binary-filter n sequence))) (foo-rep '(q c4 mf d4 e4 e f4 ppp g4 a4 b4) '(1 0 1 1 0 1 1) :omn t) -->(q c4 mf -1/4 q e4 mf e f4 ppp -1/8 e a4 ppp e b4 ppp);??

Thank you!

Hi, When I write a file to disk with the plot functions (e.g. pitch-list-plot), and I print out that plot in DIN A4 Landscape size the resolution is poor. Is there a way to change the resolution/size of the .png that is written? Thanks! ole

thanks a lot!

You are welcome! Maybe Janusz can chime in and tell us something about how to handle tied notes in functions like this. I really would like to know that!

Hi Julio, I've found two problems. The weird one you had I think I could find and solve, but the function also does not handle tied notes properly and I have no idea how to remedy that. That goes waay above my hacking abilities :-) (length-staccato 1/16 '((e. c4 eb4 fs4 a4 tie) (s a4 e. cs4 e4 g4 e bb4 tie) (e bb4 e. d4 f4 gs4 s b4))) -->((s c4 -e s eb4 -e s fs4 -e s a4 -e) (s a4 cs4 -e s e4 -e s g4 -e s bb4 -) (s bb4 - d4 -e s f4 -e s gs4 -e s b4)) Nevertheless the code with the one correction, so it's not perfect but maybe somehow useful for you.. best ole (defun length-staccato (n alist) (let ((newlengths (loop for i in (omn :length (flatten alist)) when (> i n) append (list n (* -1 (abs (- i n)))) else collect i))) (if (omn-formp alist) (omn-to-time-signature (make-omn :length newlengths :pitch (omn :pitch alist) :velocity (omn :velocity alist) :articulation (omn :articulation alist)) (get-time-signature alist)) newlengths)))

Did you see my workaround in the post mentioned by André (to lock the smpte of the track and then change the overall tempo in Logic)? Now I'am working with Reaper (https://www.reaper.fm/ ) which is worth to checkout, very cheap and unbelievable powerful (a bit of a learning curve I admit), no problem to change the tempo of every midi file seperatly.. best ole

Hi, Just a minor improvement, the function is now also working with sublists :-) best ole (defun length-staccato-lists (n alist) (let ((newlengths (loop for i in (omn :length (flatten alist)) when (> i 0) append (list n (* -1 (abs (- i n)))) else collect i))) (if (omn-formp alist) (omn-to-time-signature (make-omn :length newlengths :pitch (omn :pitch alist) :velocity (omn :velocity alist) :articulation (omn :articulation alist)) (get-time-signature alist)) newlengths))) (length-staccato-lists 1/16 '((q e4 mp q tasto q -q q q)(q e4 mp q tasto q -q q q))) -->((s e4 mp -e. s e4 tasto -e. s e4 -e. -q s e4 -e. s e4 -e.) (s e4 -e. s e4 tasto -e. s e4 -e. -q s e4 -e. s e4 -e.))

thanks for the quick answer! So the floating point numbers velocity ranges from 0.1 to 0.99 or how do it relate to the 1-127 midi steps? I want to create an as-smooth-as-possible crescendo from the lowest possible value to the highest over x steps.. Can you point me to some more information about 'floating point numbers velocity'?

Hi, I have a list of 30 midi-velocities that I want to map to 30 pitches, how can I do that without converting the velocities into symbols? Is that possible in OM (it is not for human players but for virtual instruments)? (setf vel '(1 5 10 14 19 23 27 32 36 41 44 50 53 57 62 66 71 75 79 84 88 93 97 102 105 109 114 118 123 127)) converted to symbols it looks like: (ppppp ppppp pppp pppp pppp ppp ppp pp pp pp p p mp mp mp mf mf f f f ff ff fff fff fff ffff ffff ffff fffff fffff) which is not as 'smooth' as I want it..but make-omn seems to handle only velocity-symbol or am I missing something? thanks for help!
