-Score object
score object는 non-realtime computing에 주로 사용되나 realtime으로도 사용가능하다.
score object는 OSC메세지를 사용해야하며 the various convenience methods사용을 할수 없다.
OSC message
/s_new, synthdef, node, action, target
action (0 is add to head, 1 is add to tail)
targett is target ID (e.g. 0)
/c_set, bus index, control value
this message should conclude the messages for non-realtime use
Score object는 메세지를 보내기 위해 beet단위의 메세지 리스트를 포함한다.
그 리스트는 non-realtime에서는 /c_set을 사용해야하며, realtime에서는 unnecessary.
// make an instance
z =Score.new
//define a list of timed OSC commands
(
x = [
[0,[s_new,sine1,1000,0,0,freq,62.midicps]],
