just wondering?
Why
'(#|1|# line1)
Why not
omn: line1
`(#|1|#, line1) is the same as (list line1 ) . Adds an extra level of () to line1
#|1|# is a comment and can be added anywhere: omn: #|1|# line1

Good point.
I am too lazy to write the full name. And I tend to hit wrong keys. I might end up with "Nid 1". The 0 is easy.

Besides the option of compile-score you can save from the midi-player
Tools-> last-score->midi player (or anything to the midi player).
Then in the menu (left upper-corner ) of the midi player -> save as -> give the file a name and destination. Import in DAW.
Regarding ((0 . "Bus 1")) :
In the score you write :port 0 when you want to send to your IAC-driver Bus 1.
(inst1
:omn omn1
:port 0
:channel 1
)
In logic etc set the track midi-input to all or BUS 1.Make sure that in the MIDI-settings of the DAW the IAC-driver bus is active.
In the Audio-midi-setup.app menu -> window (in German Fenster) -> MIDI-studio -> IAC-drivers you see the names of the IAC-driver and can create new ones.
(midi-destinations) is listing them counting the opusmodus port starting from 0. That is why ((0 . "Bus 1"))

I think for this kind of tasks it could help to have functions like this:
(send-midi-note :note 60 :velocity 20 :chan 0 :dest 0 :dur 'q)
(send-controller :num 1 :val 60 :chan 0 :dest 0 :dur 'q :endval 10)
Bypassing score, notation, midi-player, live-coding.
Just instant MIDI-output on cmd-e or inside of code.
Then you could write functions ,loops or just for testing or setting up your devices.
What do you think?
I assume live-coding-midi is not made to run inside of a functions.

Wasn't the initial question why this throws an error:
(setf chords '((h a2a3c4 c4a3a3) (h d4f3g2 f4g3d4) (h e4c4a3 c3a3e4) (h d3a3f4 w f4d4a3) (h e2e3g3 g3e4e4) (h a3f4e4 f2e3a3) (h e4g3b3 b3e3g2) (h a2d3fs2 w fs2a2e2) (h a2e3c4 c4a3e4) (h e4g3b3 b3e3g2) (h f2e3a3 a3f4e4) (h e4e4g3 w g3e3e2) (h d3a3f4 f4d4a3) (h e4c4a3 c3a3e4) (h b2a3d4 d4b3a3) (h a3a3c4 w c4a3a2)))
(pitch-variation 0 1 7 chords :type '? :seed 23)
So why does it throw an error?
When there are no duplicate notes in a chord there is no error.
Are duplicate notes in a chord not allowed? They make no sense, but could have been randomly generated.
-
-
(setf chords '((h a2a3c4 c4a3a3)))
(pitch-variation 0 1 7 chords
:type '? :seed 23)The first bar already returns an error.
If you change the duplicate a3 in the second chord it will work. Why two a3 in a chord?
On the other hand why not. Shouldn't throw an error.

I rewrote the function, so I can enter any length-symbol or ratio and don't have to make complicated calculations. Looks good to me and does what I wanted.
I don't use length-modify anymore. But still wonder way 'all is not a feature.
If you have any suggestions regarding style or other optimization please let me know.
I had entered this forum in 2015 but was into other things until release of v3. In case you are wondering. Just starting again with lisp and opusmodus.
I made a short score and my wife smiled while listening.

That is what I was looking for.
It doesn't show up on a search, but can be used.
-
(encode-seq 't) => t
(encode-seq (list 't)) => (1/32)
When the user inputs in my example :dit_length 't ,I would write
(car (encode-seq (list :dit_length))) => 1/32
to get a value for calculation.
-
Thank you o-e. That is much better. You didn't write this including doc this afternoon, did you?
length-diminution and text-to-letters I didn't know.
I learned a lot by going the complicated way.
Do you know how to convert an input of length-symbol to ratio?
In your function I think length-diminution is handling this. You can set :pulse 's .
-
another question for this function:
How could I convert a symbol input ('e) to :dit_length input into a ratio for later calculation?
A conversion from length symbol to ratio.

The function takes a string as input and returns the omn . Auditioning it will sound like a morse message. Setting :morse_output to t will output the real morse-message (for testing ..).
You can input any :pitch and the morsecode loops over the :pitch or just change the pitch of the output
What I was looking for is way to change the basic unit. This is set in the map to s (1/16).
It is Between ;; make changes for non-default units and ;; prepare for morse output.
(defun text-to-morse-omn (text &key ( pitch 'c4 ) ( dit_length 1/16 ) (morse_output nil))
"converting text -> morse -> omn-length

My first function I am writing in opusmodus and lisp. I learned a lot doing it. That was the main purpose. And maybe make strange music with it.Maybe some morse-trained person will get the message.
I had something similar written for max-for-live mainly in javascript to learn all the functions needed to put notes into a clip.
And had some musical fun with it.
-
With length-modify it seems that I can either modify notes or rests or random.
length-modify.pdf:
type 'r (rest) or 'n (note) or '? (at random), if not specified random type is used.Wouldn't :type 'all also be useful?
I could use it for what I am doing now.
Now I realized it by calling :type 'n and :type 'r one after the other.
Is there another function that would modify all (rest and notes)?
-
Thanks. I overlooked that.
I was more thinking of a keyboard-shortcut similar to cmd-1 ,maybe shift-cmd-1, and then a new notation-view opens.
Or a context menu-item "open in new notator"
But probably all key-combinations are already used.
-
Is it possible to open a second notation view to compare two snippets or scores side by side?
-
Yes, looks complicated. I used the loop advice now. Easier to understand.
I was looking for a function without a loop, but then you have to use a lambda expression.
To get into the loop-macro with all its possibilities is still on my list. But the collect does all I need.
I get the idea that learning the loop-macro features is worth the effort.
Thanks again.
-
Thank you AM.
That would work.
I found this in the opusmodus functions.
(setf alist '((s -s s== -s -s== s== -s s -s s -s s -s==) (s== -s s -s s== -s s -s== s== -s s -s s -s==) (s -s== s -s s -s s== -s s -s==)))
(mapcar #'(lambda (x) (append x '(q) )) alist).
=> ((s -s s== -s -s== s== -s s -s s -s s -s== q) (s== -s s -s s== -s s -s== s== -s s -s s -s== q) (s -s== s -s s -s s== -s s -s== q))

Hi,
I have this list of lists (will have much more sublists) :
'((s -s s== -s -s== s== -s s -s s -s s -s==) (s== -s s -s s== -s s -s== s== -s s -s s -s==) (s -s== s -s s -s s== -s s -s==))
I want to append e.g. a 'q to the end of each list.
Is there a function I could use?
How would you do this?
-
Hi,
it says in "Introduction to Opusmodus" :
Then there is Stages: a 30-part collection of score-scripts and text commentaries designed to be opened simultaneously. Both these are available as a download: a PDF file formatted as a printable A4 book.
I see the 30 Stages but where can I find the pdf to download?

Thanks for GEN-CONTROLLER. Just found it.
P.S: Why is GEN-LOOP not listed in the library?
Rolf
-
Thanks Stephane,
very good. That gives you all possibilities.
It is described in the length.rtfd and I have overlooked it. :-)
Length 8 will produce 8 bars of whole-notes lengths.
'(8 h q q)
-
I got it:
'(10 a2c4g4d5)
easy.
Is it in the language description somewhere and I didn't find it?
I found this: To assist with multiple rests (-12) will produce 12 bars of whole-note rests. So I tried without minus.

Exactly.
But , why not. There is no harm in comments. If it helps for any reason.
The original problem seems to me, was:
:omn '(line1)
That does not work, because line1 is not evaluated, but given to :omn as a symbol.
:omn line1 should work.
If for any reason I can't see there needs to be an extra () , (list line1) will do.
I didn't look into counterpoint yet. Maybe things have to be done differently.
Tom, could you try :omn line1 instead of :omn '(line1) and see if that solves the original posted problem?
Try with #|1|# or without. There is no difference.
You probably know about comments: ; ignores everything to end of line.
#|......|# ignores everything between #| and |# . So you can comment several lines of code.
#!......!# works in opusmodus. It is not mentioned in the Common-lisp-Hyperspec but handy on my German Apple keyboard.
