SharedIn has been deprecated. Synchronous access to busses on local servers is possible via
|
||
|
|
link::Classes/Bus#-getSynchronous:: and link::Classes/Bus#-setSynchronous::
|
||
|
|
::
|
||
|
|
|
||
|
|
Reads from a control bus shared between the internal server and the SC
|
||
|
|
client. Control rate only. Writing to a shared control bus from the
|
||
|
|
client is synchronous. When not using the internal server use node
|
||
|
|
arguments or the set method of Bus (or /c_set in messaging style).

@section{argument}
|

|
numChannels
|
||
|
|
|
||
|
|
the number of channels (i.e. adjacent buses) to read in. The
|
||
|
|
default is 1. You cannot modulate this number by assigning it to
|
||
|
|
an argument in a SynthDef.
