Detailed Description

Structure of a single tone.

This structure contains all data elements which characterize a single tone. Each tone carries an identifying keynumber. The tone is characterized mainly by the sound (static properties) and the envelope (dynamics).

The clock variable counts the number of samples from the beginning of the tone. The clock_timeout limits the maximal duration of a tone. The variables 'stage' indicates the dynamical state of the envelope.
