RST Posted July 17 Share Posted July 17 Greetings all: Is there such a function for removing a bar, or a contiguous number of bars from an OMN sequence? I have been working with "dictum" but I have not been successful in achieving my goal. In this case I have a piece with 24 measures and I would like to remove bars 16 and 17 and rewrite the sequence with these omitted. Thanks for any tips on this. I found this way to do it: (setf piano-omn-d-e (compile-score '((piano :start 1 :end 15) (piano :start 18 :end 24)))) But, I wonder if this is the only, or "best" approach. Is there any function that will work to "edit" at the beat level within a bar of OMN? Quote Link to comment Share on other sites More sharing options...
jesele Posted July 18 Share Posted July 18 This might work. (defun remove-bars (omn-seq bars) (loop for barnum from 0 and bar in omn-seq unless (member barnum bars) collect bar) ) (setf res (remove-bars material '(17 18))) ;; remember that the first bar is bar 0 so you might have to write '(16 17) Jesper RST 1 Quote Link to comment Share on other sites More sharing options...

RST Posted July 18 Author Share Posted July 18 Remove bar seems to work on a "sequence of bars" but it did not work for me on a formatted OMN stream of data. Is there a formatting or use suggestion for doing that? The documentation shows the argument as sequence and there is only one example of use in the documentation.

I will try this and see what I can do. Any thoughts for doing this on the level of the beat (meter) of the bar? Comment and help is greatly appreciated!

jesele Posted July 19 Share Posted July 19 Couldn't you use (omn-to-measure material 4/4) remove the bars, then (flatten-omn material) Jesper Quote Link to comment Share on other sites More sharing options...
