Order of evaluation and ratios
julio d'escrivan replied to julio d'escrivan's topic in Support & Troubleshooting
Hi J, I think I obtained the result I wanted, but I am not entirely sure I understand the process... I wanted 5 versions of the original list where each element had its 8ve randomised, as opposed to each sub-list being transposed, and I obtained that. I just want to be sure I understand the order of execution of operations upon a list when they are nested. It seems each function is executed completely before moving to the next outer function, thus passing a list to the next function (as opposed to each element in turn, which I think is what happens with a stream). I gue -
Hi, Sorry if this is too basic!! I'm trying really to understand details in the order of evaluation. In a recursive line, does the inner nest always produce ALL of its elements before passing the list to the outer nest? in the example below I think this is what happens: 1. randomize-octaves in the list x, the randomise operates on each element of the list in turn and thus creates a new list 2. evaluate that 5 times, thus creating five list with different octave randomisation because the seed is nil 3. the 5 lists are modified where each sequential el

generating written out accelerando...

wow, thanks! that is some programming, I don't understand the function but it does what I need, thank you, very much! -

julio d'escrivan replied to julio d'escrivan's topic in Support & Troubleshooting
Thank you, yes, I understand this software is very notation oriented, perhaps I am asking too much... I have recently seen it done on symbolic composer so I wondered if it was possible here, I can't remember the specific function, but it was not a tempo change. thanks again. -
distributive-square examples don't run
julio d'escrivan replied to julio d'escrivan's topic in Support & Troubleshooting
er... thank you, I will, but what you see above was a cut and paste from the documentation... thanks for showing the right way but then the help example needs correcting, and accounting for all input arguments, no? here it is again straight from the help file: Examples: Using the function GEN-LENGTH to make the conversion to lengths: (gen-length '8 ds-i2) => (1/2 1/4 1/4 1/2 1/4 1/8 1/8 1/4 1/4 1/8 1/8 1/4 1/2 1/4 1/4 1/2) (gen-length '16 ds-i2) => (1/4 1/8 1/8 1/4 1/8 1/16 1/16 1/8 -
Hi J, (or anybody else who knows?) I am trying to find what function generates a written out accelerando... in other words something like this starting in whole notes and down to thirty seconds: w h h e e e e s s s s s s s s t t t t t t t t t t t t t t t t or involving tuplets also, or better still, starting from a given rhythmic value (lengths in opmo?) a geometric progression of lengths. In Supercollider, we use Pgeom and give it a start and end and a multiplier and this allows fro some great accell, stutter effects. What would be

Hi J, I am trying to run the distributive-square examples, evaluating all the previous lines before hand (with the exception of the ones that show the output!) so first I run: (setf ds-i2 (distributive-square (interference2 '(3 2)))) ;;then... (gen-length '8 ds-i2) and I get this: Error: The value 8 is not of the expected type list. > While executing: gen-length, in process Listener-1(7). > Type cmd-. to abort, cmd-\ for a list of available restarts. > Type :? for other options. Also, the argument and values list f

the arp articulation in make-omn
julio d'escrivan replied to julio d'escrivan's topic in Support & Troubleshooting
ok, I have looked at the examples and the only thing I see clearly is that duration-add is necessary if there is a negative duration indicated. But I don't understand a negative duration... what you call length in omn is the rhythmic position within the bar, let's say the point at which a sound is triggered (MIDINote On timestamp?). What you call duration is how long that sound is triggered for (MIDINoteOff timestamp?). If that is correct, what does a negative duration do? I don't understand why a duration-add needs to exist... it seems to allow extending the durations by a factor. -
disappearing text in document, bug?

Hi J, I have done everything you indicate but this is happening again and it is very frustrating but I think I found a workaround: made a new workspace folder created a couple of new files and saved them manually to that folder they appear when I launch but when I start navigating from one to another at some stage they go blank the workaround I found is to manually close all documents open in the composer window, then click on the file in the navigator again and I got it back... It's like the IDE crashes when you have too many docs open in the comp -
the arp articulation in make-omn
julio d'escrivan replied to julio d'escrivan's topic in Support & Troubleshooting
thank you! I found what duration-add is by searching for an example in the documentation, the helpful just mentions the keyword but no more. I had no idea about this... we keep learning! thanks again. -
Hi J, I am trying to arpeggiate some chords put together algorithmically, I am following the example document for arpeggios, no2. And adding arp at the articulation keyword for make-omn, but I get an error, so I am wondering if it is just not possible to arpeggiate chords that are changing in the amount of sustain the notes have? (what you call 'duration' in OM language)). My basic premise is that I cannot change the original rhythmic positions of the coreCall set below, yet I want to create different orderings with different octaves and make them sound more legato:

2nd evaluation is different...

ah, ok, thank you!!! -
Hi again! :) I am setting these pitches: (setf pitchOnlyFirstCall '(bb5 bb5 bb5 bb5 gb5 db6 f6 eb6 bb5 eb5 ab5 gb5 db6 f6 eb6 bb5 eb5 ab5 eb5 eb5 eb5 eb5)) then I want to reverse and transpose down so I do this: (setf leftHand (pitch-transpose 'c0 (nreverse pitchOnlyFirstCall)) ) and the first time I evaluate the snippet I get what I want, the second time I evaluate the snippet I only get one note... So, The helpfile says that nreverse 'destroys the argument', does that mean that the variable I just passed becomes unassigned and this is w

thanks, I did as you suggested and observe in the finder that of the files that were showing blank, there are duplicates which I did not create (purposefully at least!) and which have a tilde after the name, look at my finder in the picture attached. Don't know how this happened. Anyway, I have started a new workspace within the same folder I have been working all along... thanks.
