  1. until

    Is there any chance of recording these sessions as I can't always make it on a Saturday due to I teaching all day? The first one was excellent and very useful. All best Brian
  2. 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?
  3. 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
  4. the new installation didn't create a new folder in my home directory
  5. Can you tell me where that folder is located? Can't seem to find it.
  6. 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:
  7. Sorry to hear about Nigel's passing. Do we know when and how we can pass condolences to his family? Thanks Brian
  8. 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)))
  9. Thanks André, I am going to have so much exploring this tomorrow. Best wishes Brian
  10. Thank you. No, I've only ever used libraries when working with spectral tools. I'll have a look. Best, Brian
  11. 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
  12. Thanks André, I'll give it some more thought. Best wishes Brian
  13. 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
  14. 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)
  15. 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?
