Dear Friends, Very basic question: I use some old VSL sample .gig files with gplayer. I really like this libraries and the way it sounds. The combination patches alternate sounds via keyswitches in the lower range of keyboard (or the upper range in some instruments). Something like: C normal sound C# pizz D marcato etc Can I use this keyswitches in the OMN lingo, without having to send the midi note itself to activate the keyswitch, something like: (marcato e c4 d4 s legato fs4 g4 cs5 eb5 ) Opusmodus will send the keyswitches as a hidden midi note in the expression ? All the best, Julio

Dear Friends, Avner, I noticed exactly the same behaviour. I feel a contradiction in having two results for something called "the closest path", because "the closest path", in my interpretation, means only one solution: the one in which the sum of the semitones of all voice-leading moves are the less. It's logically impossible to have "the closest path" with two solutions. You cannot have the cake and eat it too... If the function alternate between two solutions, maybe could be the case that two solutions would sum the same amount of semitonal moves, but the example above do not seems to be that case. After I realized it, I tried to find a way to assure a more accurate expression to represent that one "closest" solution. Janusz, what do you think ? All the best !! I love Opusmodus !! Thank you ! Best, Julio

When I try to open an XML file generated in Opusmodus snippet in Musescore 3, I get a message (File Corrupted). I have to open it in Finale and then export as XML. After that I can open it in Musescore. I do´t know why... But I decided to report it to you. Best, Julio

Dear Friends, Here 's a way to produce chords from 12 tone rows (Schoenberg opus 25 row): (setf op25arnie '(e4 f4 g4 cs4 fs4 ds4 gs4 d4 b4 c4 a4 as4)) (respell (gen-chord2 20 '(3 3 3 1) op25arnie)) Hope it helps a little. Best, Julio Also check this ! And the Nigel Morgan Parametric Composition book, of course ! More specific, to keep track of the row: (setf op29webernLib (expand-libraries '(library vienna webern r19))) (setf rowint (pitch-to-integer op29webernLib)) (setf pitches (gen-repeat 10 op29webernLib)) (setf lengths (span pitches (gen-repeat 10 '(s s s s -s s e -s s s -s e e -q q)))) (setf text (span pitches rowint)) (def-score Stage-1 (:key-signature 'chromatic :time-signature '(4 4) :tempo 80 :layout (treble-layout 'piano-rh)) (piano-rh :length lengths :pitch pitches :text text ;:velocity dynamics :channel 1 :sound 'gm :program 'acoustic-grand-piano) ) Best, Julio

Let's take one example: Take a set of 12 melodic patterns, like this: (setf jazzpit (substitute-map '( (s c4 d4 e4 g4) (s c4 d4 g4 e4) (s g4 e4 c4 d4) (s c4 d4 f4 g4) (s c4 d4 g4 f4) (s g4 f4 c4 d4) (s c4 d4 g4 f4) (s g4 gb4 f4 g4) (s g4 gb4 f4 a4) (s d4 f4 g4 a4) (s a4 g4 f4 d4) (s d4 f4 g4 c5)) '(0 1 2 3 4 5 6 7 8 9 10 11) '(0 1 2 3 4 5 6 7 8 9 10 11))) In this way, when I evaluate the substitute map, a got exactly the justaposition of the 12 four note patters one after another, like this: If I want to have all the patterns connected by (for example) one semitone, I can MANUALLY arrange all the transpositions in a way that the connection by semitone is achieved, like this: (pitch-transpose '(0 6 2 3 11 8 9 6 5 11 10 11) jazzpit) But I have calculate this transpositions MANUALLY, one by one, figuring out, depending on the order of the patterns, wich transposition will give me the connection by semitone. Evaluating the expression above I get this: There are EXACTLY the same patterns of the example before transposed to connect to each other by semitone. THIS IS THE POINT: I can achieve it just because I know BEFOREHAND the order of the patterns. If the process of ordering the patterns is done randomly, how can I figure out the transpositions ?? I'll explain: Let's look to another example: Let's say I have exactly the same 12 patterns but with the order choosen randomly by a rnd-unique function, like this: (setf jazzpit (substitute-map '( (s c4 d4 e4 g4) (s c4 d4 g4 e4) (s g4 e4 c4 d4) (s c4 d4 f4 g4) (s c4 d4 g4 f4) (s g4 f4 c4 d4) (s c4 d4 g4 f4) (s g4 gb4 f4 g4) (s g4 gb4 f4 a4) (s d4 f4 g4 a4) (s a4 g4 f4 d4) (s d4 f4 g4 c5)) '(0 1 2 3 4 5 6 7 8 9 10 11) (rnd-unique 12 '(0 1 2 3 4 5 6 7 8 9 10 11)))) Now, each time I run this expression, I will get a different order of the same 12 patterns, like this: FIRST RUN: SECOND RUN ETC... In each case, the order of transpositions to make a connection between each four-note patterns by semitone could not been calculated manually because I don't know beforehand what will be the result of the expression. I would need a kind of buffer function that informs me what would be the first and last note of each pattern after the rnd-unique, so with this information, I could find a formula to map this information with the transposition sequence, in order to connect every pattern with a semitone between the its last and first note. I don't know how to antecipate the result of a random process, or to have it inside a loop of decicion making process inside Opusmodus. Please, let me know if I was clear in the explanation. Best, Julio

Very nice, Jordv ! I'm very interested in Harmony. Let me know about your progress in this matter. I did a book about set theory and harmony. If you play guitar, you gonna like it. It have all the possible voicings with diagrams for guitarand much more, like hexatonics, voice leading, functional harmony, etc. Here's the link https://www.melbay.com/Products/30042BCD/combinatorial-harmony-concepts-and-techniques-for-composing-and-improvising.aspx And another post related to it All the Best, Julio
