[Subdivision display options?]

Hi,

 

This code:

((e a4 mf - - gs4 f - - g4 p - -)
 (-e a4 p - - gs4 - - e4 -))

 is displayed like you see in the 2 screenshots, the second of the snippet notation, the first of the ps function (with :timesignature '(9 8))

Also in the xml-file are quarter-rests* written (as in the screenshots), is there a way to set the subdivision (which looks right in the code)?

 

Thanks!

 

*which is "ok" in the first bar, but very hard to read in the second one..

[Dictum question]

Ok, thanks  for the explanation!

And in the meantime I did get why position-insert does not work on the omn level,  so sorry for the noise!

[Dictum question]

I see a second cs4 in Julios second example and can't find it in Stéphanes solution, what am I missing?

 

And should'nt that work:

(:apply (position-insert 1 'cs4 x) :bar 7)

? It does give a strange result..

 

Thanks for an answer!

[Using variables for keywords, possible?]

Ok, so I have a (so far ready)OM-score and I want to mute (= change into a rest) every other note (regardless of changing meters). How would I do that?

 

Thanks!

[position-filter??]

Hi,

 

(setf test-flatten (flatten 
                   '((q a4 -e gs4 e4 -)
                    (q a4 e - e4 d4) 
                    (-e g4 e4 - q a4) 
                    (-h.) 
                    (-q e a4 gs4 - g4))))

(setf por (length-rest-position test-flatten)) 
==>(1 4 7 10 13 15 16 19)

  (setf sr (position-filter por test-flatten))
==>(-e - - -)
;should be this:
;  (-e - - - - -h. -q -e)
;or do I miss something?

Thanks for assistance!

[Using variables for keywords, possible?]

Its an  accent grave and a comma, right?

How can  get some background knowledge about that, what is it called, I remember I saw that  before..

Anyway thanks a lot Stéphane!!

[Using variables for keywords, possible?]

Hi,

 

(setf test '((q a4 mf e a4 p e gs4 f  e4 mp g4 p) 
               (q a4 e e gs4 e4 d4)))
(setf one '(1 3))
(dictum '(:remove :event :bar 1 :event one) test)

This gives an error, is there a way to use variables for keywords?

 

Thanks and Happy Easter everybody

 

Edit: Just checked another function (randomly choosen). Here a variable for a keyword works fine.

My guess is that it has to do with the quotation mark inside the dictum, is there a way around this?

 

(setf test-2  '((q a4 mf e a4 p e gs4 f  e4 mp g4 p) 
               (q a4 e e gs4 e4 d4) 
               (e e4 g4 e4 g4 q a4)))
(setf sec '(0 2))
(pitch-transpose '(7 -5 ) test-2 :section sec)
==>((q e5 e p eb5 f b4 mp d5 p) (q a4 p e e gs4 e4 d4) (e b3 p d4 b3 d4 q e4))

I know, but can tbe user set it to nil? Is there maybe a preference?

@André: isnt it so, that the length value is valid until the next length value regardless if its a rest or not?

Please correct me if I'am wrong..

Thanks, as I wrote above, I've already discovered this, but what about the snippet preview? Is it possible to set it to nil there?

Thanks, but where to put this? I know I can put this inside ps, but what about the snippet preview?

Hi,

 

Sometimes I got so many clef changes in the snippet preview that it is hard to read (at a glance), is there a way to surpress this?

Hi,

Does dechord only work for triads (as described in the docs)?

[score-player latency??]

 

That evaluating one after the other def-score did the trick, thank you very much!

I like these Conlon Nancarrow possibilities a lot 

[score-player latency??]

Thanks for the super quick answer!

So you don't have latency?

I've tried it both with Vienna Ensemble and GM-MIDI Player- same result

 

@Andre: Can you explain what do you mean by evaluating step by step, please?

Did you tried the example that I posted?

When I run the following code I get a terrible latency between the voices. Do I miss something or is it a bug?

[play polytempo -> code/examples]

I try to evaluate score1 and score2 seperatly but the DAW can only read one tempo map at a time

So, I don't see a way beside recording the midi-stream..?

[play polytempo -> code/examples]

Can you please examine the midi file, maybe its a bug in my DAW?

I've tried it also with quicktime player (7), there is also only one voice..

Edit: MIDI Player X also plays only one voice (the second as in the screenshot below).

Thanks!

tempomodulation.mid

[play polytempo -> code/examples]

Thank you!

As the time-signature is 1/4 now, there is a change in the tempo definition necessary:

(setf tempo (mclist (gen-integer 160 10) (gen-repeat 150 1)))

then the two instrument's start and end together as it should be..

Can't wait for the score-player doc, any chance the midi export function can work correctly? It is cumbersome to record the midi-stream..

Anyway thanks a lot for this!!

PS I do not understand why this:

(mapcar 'list (gen-integer 110 60)(gen-repeat 50 '1))
==>((110 1) (109 1) (108 1) (107 1) (106 1) (105 1) (104 1) (103 1) (102 1) (101 1) (100 1) (99 1) (98 1) (97 1) (96 1) (95 1) (94 1) (93 1) (92 1) (91 1) (90 1) (89 1) (88 1) (87 1) (86 1) (85 1) (84 1) (83 1) (82 1) (81 1) (80 1) (79 1) (78 1) (77 1) (76 1) (75 1) (74 1) (73 1) (72 1) (71 1) (70 1) (69 1) (68 1) (67 1) (66 1) (65 1) (64 1) (63 1) (62 1) (61 1))

(mapcar 'list (gen-integer 60 110)(gen-repeat 50 '1)) 
==>((60 1) (61 1) (62 1) (63 1) (64 1) (65 1) (66 1) (67 1) (68 1) (69 1) (70 1) (71 1) (72 1) (73 1) (74 1) (75 1) (76 1) (77 1) (78 1) (79 1) (80 1) (81 1) (82 1) (83 1) (84 1) (85 1) (86 1) (87 1) (88 1) (89 1) (90 1) (91 1) (92 1) (93 1) (94 1) (95 1) (96 1) (97 1) (98 1) (99 1) (100 1) (101 1) (102 1) (103 1) (104 1) (105 1) (106 1) (107 1) (108 1) (109 1))

gives a different result than this:

(gen-integer 110 60)
==>(110 109 108 107 106 105 104 103 102 101 100 99 98 97 96 95 94 93 92 91 90 89 88 87 86 85 84 83 82 81 80 79 78 77 76 75 74 73 72 71 70 69 68 67 66 65 64 63 62 61 60)

(gen-integer 60 110)
==>(60 61 62 63 64 65 66 67 68 69 70 71 72 73 74 75 76 77 78 79 80 81 82 83 84 85 86 87 88 89 90 91 92 93 94 95 96 97 98 99 100 101 102 103 104 105 106 107 108 109 110)

 

[play polytempo -> code/examples]

I made a simple example to show how it works.

You have to set the port and the midi channels to your needs.

What I don't get is why the two voices of different length, any explanation is welcome..

The OM MIDI-Export function does not work here, so you have to record the MIDI-Stream in your DAW.

Enjoy!

Hi,

I was fiddeling around with your code below, but I don't get it, can you please explain a little more how it works, when I test it the tempo of instrument1 to 4 are still in the same tempo (inside one play-tempo-stream (), when I try the play-tempo-streams at the same time, it throws me an error. Can you please provide a simple Conlon-Nancarro-ish 2 voice example or something to work along?

Thanks in advance!
