control — Configurable slider controls for realtime user input.
Plugin opcode in control.
Configurable slider controls for realtime user input. Requires Winsound or TCL/TK. control reads a slider's value.
Note that this opcode is not available on Windows due to the implimentation of pipes on that system
knum -- number of the slider to be read.
Calling control will create a new slider on the screen. There is no theoretical limit to the number of sliders. Windows and TCL/TK use only integers for slider values, so the values may need rescaling. GUIs usually pass values at a fairly slow rate, so it may be advisable to pass the output of control through port.
