/*! \page instruments Instruments
|
|
|
|
The ToolKit comes with a wide variety of synthesis algorithms, all of which inherit from the Instrmnt class. In this example, we'll fire up an instance of the BeeThree FM synthesis class and show how its frequency can be modified over time.

|
\include bethree.cpp
|
|
|
|
We have used an Instrmnt pointer when referencing the BeeThree instance above, so it would be simple to replace the BeeThree class with any other STK instrument class. It should be noted, however, that a few classes do not respond to the setFrequency() function (e.g., Shakers, Drummer).

The noteOn() function initiates an instrument attack. Instruments which are continuously excited (e.g., Clarinet, BeeThree) will continue to sound until stopped with a noteOff(). Impulsively excited instrument sounds (e.g., Plucked, Wurley) typically decay within a few seconds time, requiring subsequent noteOn() messages for re-attack.

|
Instrument parameters can be precisely controlled as demonstrated above. A more flexible approach to instrument control, allowing arbitrary scorefile or realtime updates, is described in the next tutorial chapter.
