Hi all,

is there any object that allows to do a melodic inversion?
The input would be the numeric values ​​of the midi notes.

(Melodic Inversion in the sense that where the original melody goes up by an interval, the inverted melody goes down by the same interval).

Thank you,
a.

For chromatic intervals, just use [-] -- like, if you want middle C to be the reflection point:

(your MIDI note)
|
[120 $1(
|
[-]

For diatonic intervals, you'd need to convert to a diatonic representation, then subtract, and convert back.

Thank you.
In my case I would like the reflection point to be the first note of the sequence.

Maybe this works:

Let MIDI_1 = first MIDI note of the melody

(MIDI note from a list from first to last)
|
(2*MIDI_1, $1)
|
[-]

So, for example:

(71 68 74 51) becomes: (71 74 68 91)

I "just" have to build this object that acts on a list of any length

Nice, it works perfectly.
It could be added in "else/list management" as [inversion] object.
(Maybe adding a number box to choose the reflection point. Without choice: the first element as reflection point by default).

Thank you,
