Live arranger script


Recommended Posts

Is it possible to write a script that combines a chord detection tool with a transposer tool?

Let's say we have several midi tracks / loops in the key of C Major...If someone plays a chord the script would automatically detect and transpose the midi track to that chord and scale. Of course individual notes should be transposed slightly differently depending on if the chord is major or minor.

This way logic could be used as an arranger and you could put down ideas quickly by designing the accompaniment "loops" or tracks and playing / recording the chords in real time

IMHO, that would be beyond the scope of a single script…

Consider that a same chord could belong to many different scales… Additionally, compositions often borrow notes ifnot chords to other (neighbour) scales.

Some plugins/apps (such as Scaler or Captain Chords) could be useful in that endeavour.
