I want to create a "Bass Machine" patch in which when the user plays a chord on the MIDI keyboard, MAX outputs both the chord and the relevant bass note, say 2 octaves below the root. I know chord analyzation is tricky, but, if I limit my user to playing triad chords in root position only, all that MAX needs to do is play the lowest of the notes in the chord 2 octaves lower. My attempt to tackle the problem was as follows:

[Notein] ---> [Stripnote] ---> [Thresh 20] ---> [Unpack 1 2 3] ---> [int boxes]

at this stage the theory is that I'll now have the 3 notes of the chord seperated into int boxes. Then all i need to do is find the lowest number from the three int boxes.

My attempt at this was to first find the lowest number in boxes 1 and 2 by using the IF function: [if $i1

This method works sometimes but often il get the wrong bass note out. Does anyone have any better ideas on how to go about the whole thing?

And perhaps 20ms thresh is too short 200 ms should be more valuable, if you just analyze chords... (this is 16th notes in M.M 100...) ok, if you want to track chopin etudes, it might be not enough....;.)

why dont you use the minimum-object?

if you just want the lowest not (int) of a group (list) why not use [zl sort] ?

Fantastic! Both of them work. I think il stick with minimum, does what it says on the tin.

Seeming as that was so simple, is there a way to reduce the limitations on the user such allow them to play not strictly in root position?

Tho i guess now they can play more than 3 note chords, as long as the root is at the bottom, which is a limitation lifted.
