Clip Play Poly Mode optional layout and functions
In order to have more subdivisions on the polymodes, instead of the columns, each row in the matrx will control either the Clip that is playing or the Clip that is selected on the corresponding Track. (Each row would be related to first 4 or 5 tacks in the grid selector)
On poly submodes the matrix accessory buttons would be used to select and show the playing clip of the corresponding track.
Shift+ matrix accessory buttons: Quantization
Loop and Play toggle buttons:when holding these and pressing the matrix accessory buttons would toggle play/stop and loop of the corresponding track.

Admin note: Modified title of idea as, if it were implemented, it would apply to all Arsenal scripts with a matrix, not just Arsenal_AP4.
