  1. I think I know what the problem was, I can not copy directly from the browser. 'Text Wrangler' shows me lots of otherwise hidden signs that confuses OM and that I have to remove first. Sorry for the noise. That was probably the same problem with Yuichis Code.. edit: Yes ideed!
  2. Dear Torsten, Thank you very much for your solution. It looks very promising, in a good sense simple. Unfortunatly, when I tried to eval your "cut-holes" function it throws an error: Error: ((= b 0) (* l -1) l) can't be destructured against the lambda list (ccl::test true &optional false), because it contains 5 elements, and at most 3 are expected. and I could not find out whats wrong. What am I missing? ole
  3. Hi Yuichi, Thanks for your efforts! Unfortunatly the listener gives me a 'no current expression' when I try to evaluate the 'skip-notes' function and I do not find what is wrong at first glance. Maybe you can repost your code using the '<>' code-brackets in the posting window. Not sure if this helps though. best ole
  4. Hi, I want something rather simple, a sort of sieve, how can I achive that? Lets say I have a melody like (q c4 e d4 e e4 q. f4 e g4 q a4 b4) and I want to mute every other note, so the result would be: (q c4 -e e4 -q. e g4 -q b4) or every third note like: (q c4 e d4 -e q. f4 e g4 q a4 -q) and it would be great to have an offset.. thanks! ole
  5. Thank you so much for your bunch of solutions! I'll have to chew a while examine them, than I'll get back.. best ole
  6. Thank you for the quick reply! My material is this pattern: (1/4 -1/4 1/4 -3/8 1/4 -1/4 1/4 -3/8) now I want to create all variations of this pattern ranging from one beat: (-1/4 -1/4 -1/4 -3/8 1/4 -1/4 -1/4 -3/8)
 (0 0 0 0 1 0 0 0 ) to four beats (orginal pattern)
  7. Hi, I'am looking for a method to pick more and more elements from a list (that are more or less equally distributed): (1/4 -1/4 1/4 -3/8 1/4 -1/4 1/4 -3/8) (1 0 1 0 1 0 1 0 ) 1.pass--> (-1/4 -1/4 -1/4 -3/8 1/4 -1/4 -1/4 -3/8)
 (0 0 0 0 1 0 0 0 ) 2.pass--> (-1/4 -1/4 1/4 -3/8 -1/4 -1/4 1/4 -3/8)
 (0 0 1 0 0 0 1 0 ) 3.pass--> (1/4 -1/4 -1/4 -3/8 1/4 -1/4 1/4 -3/8)
 (1 0 0 0 1 0 1 0 ) 4.--> see orginal list thanks for any hints best ole
  8. Hi Stephane, Are you willing to share the (OM-)score for studying purposes? thanks, ole
  9. I've tried to import Data from Spear following the help-file of import-spectral-spear but did not succede. I assume I have to export the textfiles of the partial data and the frames data to the folder ~/Opusmodus/Spectral Data/Data and the described import action is related to OM? When I try (import-spectral-spear :frames "tbn cs3 frames" "tbn-cs3-frames") than: > Error: No such file or directory : #P"om:Spectral Data;Data;tbn cs3 frames.txt.newest" So it would be really great if you can ellaborate on that spectral stuff.. thanks a lot! ole
  10. Can't wait! Thanks a lot!
  11. Hi, I'am exploring the new spectral functions. Can't find GET-TUNING. Are there some more Informations on how to use the spectral data from Spear (beside IMPORT-SPECTRAL-SPEAR)? Very nice piece btw best ole
  12. Thanks for the answer! @AM: Don't know if you are using Logic, in Logic you can lock an object (midi-track) to its current SMPTE position, via right-click, also see: https://documentation.apple.com/en/logicpro/usermanual/index.html#chapter=40%26section=4%26tasks=true than choose another tempo and lock the SMPTE position again and so forth. Maybe that helps as a workaround. best ole
  13. It would be great if the master can chime in an say a few words to this topic.. thanks ole
  14. If there is a way to program a score with voices in different tempos, I'am also strongly interested how that could be done. best ole
  15. I guess gen-retro does not work with more that one voice. And you don't need the quote when calling the variable with gen-retro Don't know if it is necessary but I would put a blanc character between the name of the variable and the content (gen-retrograde 'music1) (setf music1 '((q .. hth
