Using the Interface Boxes : Example

 A minor or major triad is created with three interface boxes : multiple-items-list-box, button-box, and check-box.

• On the left the build note! button calls a series of boxes :

  1. two list-boxes allow to choose a note name from A to G, and an octave index, from 1 to 5.

  2. the resulting reference is returned as a list with three lisp functions to  n->mc^[1] ,

  3. n->mc returns a midicents value to a chord box.

• On the right, the build chord! button calls another series of boxes :

  1. The minor check box is checked and returns "true" to OMIF,

  2. OMIF returns 300, which makes a minor third. If it isn't checked, OMIF returns the value of a major third – 400 mc.

  3. The value of the root is added with 300 and 700 to build a minor triad, via two om+ boxes.

  4. The resulting values are gathered by x-append into one single list and returned to a chord box.

This pop-up box returns two types of results :

• Input #1 is connected to a textfile box, which contains a list of midi channel names . When output #1 is evaluated, it returns the midichannel number.

• Input #2 is connected to a lambda patch, which can play the sound of a selected sample.
