(defobject name supers slots [(:parameters ...)])

Defines a new class of object. name is the name for the new class. supers a list of superclasses or (). slots is a list of slot specification or (). Each slot can be either the name of a slot or a list in the form:

(slot :initform :accessor :reader :writer :initarg)

defobject automatically declares slot and adds its its keyword as an initialization argument for new and make-instance. Following slots comes an optional :parameters declaration:

(:parameters ...)

Where the arguments following the :parameters keyword are the names of the slots that are instrument parameters. Slots listed are considered to be required parameters unless preceded by a lambda keyword &optional, &key or &rest. A required parameter means that an error is signaled if the slot is unbound during score generation. &optional parameters are ignored if unbound. &key parameters are also optional but the slot value is preceded by its keyword in the output file. A single &rest parameter is a list of values that are "spread" over a number of parameters in the output file.
