Modal Change

The Modal Change object is a compositional algorithm to control modality. It outputs scale degrees and creates tables and lists that adhere to one of the 7 modes.

created by V.J. Manzo

The Modal Change object allows a user to specify a tonic and diatonic mode in its two inlets and get the pitch class value of each scale degree out its eight outlets. A user can send a pitch class number or a letter name message to its left inlet to set the tonic. A message box with a mode name such as major, minor, Phrygian, Lydian b7, can be sent to the right inlet to build up a scale from the given tonic. The object will output the scale degrees for any tonic within the modes of the major scale, the melodic minor scale, the harmonic minor scale, and the harmonic major scale (the major scale with flatted 6). Instead of using one of the mode names to build a scale, a user can also send a message with the number of whole steps and half steps desired to build their scale, and receive the scale degree pitch classes from its outlets.
Double clicking the object will open a display that allows the user to see what mode they’re in and other information related to the mode including scale degree distances that make up the scale and the particular mode’s context within the larger pitch collection.
The object can receive all of the organized pitch class data into a table or by using an internal table with the argument table1.
The object can also receive the organized pitch class data into a coll list or by using an internal coll list with the argument scale. The coll list also has an added feature: it will take any incoming pitch and filter it to the nearest note from the selected scale.
This allows you to set the tonic and mode, and filter all incoming pitch data so that whatever note is played, it will conform to the diatonic pitch collection you’ve selected.
