Defines a new class of object. name is the name for the new class. Following name comes a list of zero or more superclasses. The new object will inherit slots and behavior from each super in the list. Following this list comes the slot specification list. Each slot in the list is either the name of a slot or a list of the form:

    (slot &key :initform :accessor :reader :writer)

    (option {value}*)

defobject supports the following options:

(:parameters {slot}* {&optional {slot}*}* {&key {slot}*}* {&rest slot}* )

Declares each slot to be a parameter of the object. A parameter is a slot whose value contributes to the makeup of a musical event. The order of slots in the parameter list defines the order in which they are examined during event processing. Unqualfied parameters are considered to be required, which means that an error is signaled if a slot value is not present when the output event is processed. Three additional types of parameters are supported depending on the type of object being defined: optional, keyword and rest. These parameters are marked by preceding the affected slot(s) in the parameter list with &optional, &key, or &rest. Optional parameters are not processed if unbound, keyword parameters are optional but the slot value is preceded by a "keyword" appropriate to the slot name and type of event being processed. A single rest parameter holds a list of values that are then "spread" over a number of parameters positions in the output event.
