Hi everyone,

I'm working on a project that implements a MIDI sequencer that allows you to record a melody. I´ve implemented it with tables and so far so good.
What I'm trying to do now is to extract the tonality from the recorded melody. I thought I could first use [spigot] to create a new table with [tabread], using a module 12, this way eliminating all the 0 values from the recorded melody and only maintaining the notes ranging from 0-11.

Now what I had thought was to have different tables that correspond to different scales, and compare the newly recorded table that has all the note values from 0-11 to each of the scale tables, trying to see with which table it has the most similarity.

I'm not really sure how I could get this done, but if someone has an idea I would be happy to hear it :D.

Thanks!

Did you check [chord] in the maxlib library ?

I ended up using tabletool which let's me compare two arrays, giving me the euclidean distance between them. Now I'm trying to compare the 12 numbers that output from compare the recorded sequence with each possible tonality, keeping the lowest distance as the tonality.
