inumspaces (optional, default=0) -- number of space characters printed before the value of kvar
kvar -- signal to be printed
Derived from Robin Whittle's printk, prints a new value of kvar each time kvar changes. Useful for monitoring MIDI control changes when using sliders.
Warning |
WARNING! Don't use this opcode with normal, continuously variant k-signals, because it can hang the computer, as the rate of printing is too fast. |
Here is an example of the printk2 opcode. It uses the files printk2.orc and printk2.sco.
