Hello There!s there a possible to transpose diatonically a sequence of notes or a chord? I noticed that OM transposes (+) chormatically.
Thanks for the help!

Dear Ismael,
addition transposes notes as it is, ie adds the amount of midicents you need. Diatonic transposition, is something else. I think you mean by that āSHIFTINGā a scale or a mode. by a certain degree. No?

hello,
yes, itās a shifting. How can I do it?
Thanks for replyingā¦
Ismael
thanks. I will try it here.
hello,
where you put the input 2, thereās a lisp function with a 1- below. I didnāt know that it was possible. As I see, this function is linked with the lisp nth, right? can you please tell me how to do it?
Regards and thanks for helping meā¦
Ismael
Dear Ismael,
This is a standard lisp expression. You can use most of them in om (at the exception of macros) by dble-clicking in the patch and typing the name of the functions. Works also for om functions.

Hello Haddad,
I still cannot do it. I know how to call a function. In this case, if I call lisp, it shows me a lambda function. I can alter the name and put a 1- there. But a function like list, thatās not possible to alter the name. I want to know the name of the function where you can alter the name, like you did it. Look at the image I am sendingā¦

No you got this wrong:
-
double click in the workspace:
-
type the functionās name
-
type return:
It is as simple as thatā¦ No need to call lispfunction object. This last one is for a custom lisp code you can write by yourself.
Hope this helps

ah okā¦rsrsā¦thanks!
Hello again,
Sorry to take your time Haddad. Itās a little more complicated. First, thereās an error message appearing when I try to validate the diatonic patch, saying: in 1- of (nil) arguments should be of type number. In fact, the value of input 2 is nil, and also the same as input 0. Second, the shifting is within the same scale. In the example, the scale of C major turns D major. What I want is a scale with no alteration, only shifting the position of notes. So, D, E, ā¦C, D.
Hi,
Yes as i understood you meant transposition. So if you input 2 in the second input, you will have a D major scale. Now shifting degrees is another operation. Can you be more specific? (ie a patch example will help )

Hello Haddad,
thatās why I opened this post. I want how to transpose diatonically, that is, according to the scale, not chromatically. I need it for an analysis. I think this is a tricky problem because in math we use steps to transpose but it doesnāt work in this situationā¦hope you can help meā¦
Regards,
Ismael
hello Haddad,
I wasnāt able to create a patch that can transpose degrees according to a specific scale. Can you help me do that?

Ismael
Hi All,
I apologize for inserting myself in this discussion, but in past I have afforded a similar problem, I suppose. Perhaps something as this, even if a little rough?
Or something analog, using posn-match for shifting along a scale.

Hello,
Thanks for this replying. I will try it hereā¦

Ismael
Dear Ismael,
I donāt know if this is what you are looking for, but here it is:
You can shift any notes in a given scale (here c major) by a given degree:
And here is the patch:
shift.omp (29.6 KB)
And yes it is ātrickierā than a simple transposition.

hello,
Thanks! both methods are great for me!
Resolved!

Hello Haddad,
Thatās the patch, but a little question about it. When I press to evaluate some functions inside the mode transposition, it returns the value nil. Itās because inside the āinputā, the value is nil. So, some evaluations are not functioning or returning nil. Thatās not normal right? Itās like the scale or the āsomethingā is abstracted, not been used in the red patch āmode shiftingā;
