this is what I did as I explained in my original post but I was not asked for permission to create a new OM folder. Is it imperative that OM creates the folder and if so, how do I begin the installation process again so that it does request these permissions?

Yeah, I put the old Opusmodus back in my home directory and removed the file in Extensions but the error messages still comes up when I launch OM

the new installation didn't create a new folder in my home directory

Can you tell me where that folder is located? Can't seem to find it.

Hello I renamed and compressed the OM user folder then deleted the original file as instructed. Updated, opened and entered new registration code but I wasn't asked for permission to create a new user folder in my home directory. All I get is this error message:

Sorry to hear about Nigel's passing. Do we know when and how we can pass condolences to his family? Thanks Brian

Hi Andre, loving the new function so thank you so much for creating it. How might I add my own tonality? Can I do a setf to create a scale and then insert it in TONALITY? Or do I need to add it to the library? Thanks Brian (setf my-scale (make-scale 'c2 49 :alt '(1 2 1 1)))

Thanks André, I am going to have so much exploring this tomorrow. Best wishes Brian

Thank you. No, I've only ever used libraries when working with spectral tools. I'll have a look. Best, Brian

Thanks André, yes that produces the same sequence as the c major example starting on g4. Tried it with longer sequences and with different modes: (setf pitch (step-to-pitch :steps (integer-to-interval (reset-seq (infinity-series 2848 '(1 0)))) :pitches (multiple-expand-tonality :startpitch 'c0 :octaves 7 :tonality '(minor-hexatonic)) :start 'g4)) Perfect!! I really appreciate your help with this. Combined with the new time-swallow it's amazing. Best wishes Brian

Thanks André, I'll give it some more thought. Best wishes Brian

Thanks André, I thought it might be that. It works now with the integers as they are but I still need to solve the problem of how the infinity-series projects the intervals. The integers produced by the infinity series work like this http://web.archive.org/web/20070523051434/http://www.pernoergaard.dk:80/eng/strukturer/uendelig/ukonstruktion01.html So, applying the resultant integers from the infinity-series function doesn't work. I think the scale mode would need to be built into the function? Best wishes Brian

Thanks André I tried to superimpose the first 64 infinity-series onto the c major scale but it kept returning an error? Also, I couldn't find the tonality-step function? Brian (step-to-pitch :steps '(0 1 -1 2 1 0 -2 3 -1 2 0 1 2 -1 -3 4 1 0 -2 3 0 1 -1 2 -2 3 1 0 3 -2 -4 5 -1 2 0 1 2 -1 -3 4 0 1 -1 2 1 0 -2 3 2 -1 -3 4 -1 2 0 1 -3 4 2 -1 4 -3 -5 6) :pitches '(c3 d3 e3 f3 g3 a3 b3 c4 d4 e4 f4 g4 a4 b4 c5 d5 e5 f5 g5 a5 b5 c6) :start 'g4)

So 0, 1, −1, 2, 1, 0, −2, 3, cannot be interpreted as steps up and down a pre-defined scale comprising tones and semitones (G4 A4 F4 B4 A4 etc) but only as semitone intervals?

Thanks Janusz I'm not sure if I'm understanding this correctly. If I wanted to use a scale of C major but start the infinity series on the pitches G4 A4 (or G4 B4 etc) so that it only returns notes from the C major scale, would this work to produce the following? Thanks Brian http://web.archive.org/web/20070523051434/http://www.pernoergaard.dk:80/eng/strukturer/uendelig/ukonstruktion01.html

Hello All As I continue my fascination with the fractal structures contained in Per Norgard's infinity series, I am wondering whether it might be possible to apply the infinity to particular scales or modes? Say I want to generate an infinity-series based on a pre-existing scales/modes (like in G major) or by any self-defined mode such as (make-scale 'c2 49 :alt '(1 2 1 1)) Any help much appreciated as always. Kind regards Brian

Thank you so much Janusz!! I love the way you creative lisp-coders can hear an idea and immediately create a lisp-realisation (with extensions)!!! What am amazing community. I'll look forward to the update. All the best Brian

Thank you, that's exactly what I was looking for!! Much appreciated! Brian

Hello All Can anyone help me develop a function which superimposes a rhythm onto a constant list of pitches? For example, how would I go about superimposing a rhythm like (1/2 1/16 7/16 1/8 3/8 3/16 5/16 1/4 1/4 5/16 3/16 3/8) on to list of pitches like (infinity-series 100 '(g4 gs4)) => (g4 gs4 fs4 a4 gs4 g4 f4 bb4 fs4 a4 g4 gs4 a4 fs4 e4 b4 gs4 g4 f4 bb4 g4 gs4 fs4 a4 f4 bb4 gs4 g4 bb4 f4 eb4 c5 fs4 a4 g4 gs4 a4 fs4 e4 b4 g4 gs4 fs4 a4 gs4 g4 f4 bb4 a4 fs4 e4 b4 fs4 a4 g4 gs4 e4 b4 a4 fs4 b4 e4 d4 cs5 gs4 g4 f4 bb4 g4 gs4 fs4 a4 f4 bb4 gs4 g4 bb4 f4 eb4 c5 g4 gs4 fs4 a4 gs4 g4 f4 bb4 fs4 a4 g4 gs4 a4 fs4 e4 b4 f4 bb4 gs4 g4) So that the melody would be: => (g4 gs4 fs4 a4 gs4 g4 f4 bb4 fs4 a4 g4 gs4 a4 fs4 e4 b4 gs4 g4 f4 bb4 g4 gs4 fs4 a4 f4 bb4 gs4 g4 bb4 f4 eb4 c5 fs4 a4 g4 gs4 a4 fs4 e4 b4 g4 gs4 fs4 a4 gs4 g4 f4 bb4 1/2 1/16 7/16 1/8 3/8 3/16 5/16 1/4 1/4 5/16 3/16 => (1/2 g4 1/16 fs4 7/16 a4 1/8 gs4 3/8 f4 3/16 f4 5/16 g4 1/4 fs4 1/4 a4 5/16 g4 3/16 g4) I want to set each pitch to a constant value, for e.g 1/16 then superimpose the rhythm so that rather than span the rhythm to the pitches, the rhythm swallows the pitches leaving a resultant melody. I hope this makes sense. Any help gratefully received. Best wishes Brian

Thank you!! All working. :)

Hello I followed the directions in import-spectral-spear and created a new library low-c-frames.opmo

Thanks for this. Nice easy fix. I'm having another difficulty with do-timeline when trying to do full orchestral score as in the example. All three DO-TIMELINE return this error message: 25 > > Error: The GET-SPAN output denominator is not a power of two (1, 2, 4, 8, 16, ...). Denominator: 12. > While executing: (:internal get-time-signature-l get-time-signature), in process Listener-1(7). > Type cmd-. to abort, cmd-\ for a list of available restarts. > Type :? for other options. Silly question I'm sure but where can I adjust the denominator? Thanks Brian

Thanks for your reply. So taking your score example from OM below, what would you need to change to double the length to 24 bars? Each of my partial-rows return 12 pitches each. Is this the problem? (setf partial1 (library 'tbn-cs3-frames 'partials 'p0)) (setf partial2 (library 'tbn-cs3-frames 'partials 'p1)) (setf partial3 (library 'tbn-cs3-frames 'partials 'p2)) (setf partial4 (library 'tbn-cs3-frames 'partials 'p3)) (setf partial5 (library 'tbn-cs3-frames 'partials 'p4)) (setf partial6 (library 'tbn-cs3-frames 'partials 'p5)) (setf row1 (partial-row partial1)) (setf row2 (partial-row partial2)) (setf row3 (partial-row partial3)) (setf row4 (partial-row partial4)) (setf row5 (partial-row partial5)) (setf row6 (partial-row partial6)) (setf rhy1 (gen-tuplet 1 2 'd '? (gen-repeat 48 '(q)) (rnd-sample 48 '(5 4 3)))) (setf rhy2 (gen-tuplet 1 2 'd '? (gen-repeat 48 '(q)) (rnd-sample 48 '(5 4 3)))) (setf rhy3 (gen-tuplet 1 2 'd '? (gen-repeat 48 '(q)) (rnd-sample 48 '(5 4 3)))) (setf rhy4 (gen-tuplet 1 2 'd '? (gen-repeat 48 '(q)) (rnd-sample 48 '(5 4)))) (setf rhy5 (gen-tuplet 1 4 'd '? (gen-repeat 24 '(h)) (rnd-sample 24 '(3 2)))) (setf rhy6 (gen-tuplet 1 4 'd '? (gen-repeat 24 '(h)) (rnd-sample 24 '(3 2)))) (setf vel (rnd-sample 24 '(pp p mp mf f))) (setf afl-omn (make-omn :length rhy1 :pitch row1 :velocity vel)) (setf cl-omn (make-omn :length rhy2 :pitch row2 :velocity vel)) (setf bcl-omn (make-omn :length rhy3 :pitch row3 :velocity vel)) (setf hn-omn (make-omn :length rhy4 :pitch row4 :velocity vel)) (setf vn-omn (make-omn :length rhy5 :pitch row5 :velocity vel)) (setf vc-omn (make-omn :length rhy6 :pitch row6 :velocity vel))

the base material is more or less the same as in the score example, I changed the library file and some of the numbers. I don't the system well enough yet which is why I'm trying to reconfigure some examples. B
