Saving slider values

There are several ways to initialize UI objects, but the data is not stored with the object itself (except for the Live objects). Triggering an initializing message to the object with loadbang is one way. See also loadmess, patcherargs, and pattr.

Arpeggiate the harmonic series

This example repeatedly arpgeggiates the first 16 notes of the harmonic series based on the frequency 65.406395 Hz, which is the fundamental frequency of the open C string on a cello. The note rate can be adjusted anywhere from 1 note per second to 100 notes per second. The default initial rate is 8 notes per second.

The ‘alpha’ attribute of a picture

In digital images, each pixel contains color information (such as values describing intensity of red, green, and blue) and also contains a value for its opacity known as its ‘alpha’ value. An alpha value of 1 means totally opaque, and an alpha value of 0 means totally transparent. This value can be used for blending images, or for making all or part of an image totally transparent.
