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.
Example 286. Example of the printk2 opcode.
/* printk2.orc */ ; Initialize the global variables. sr = 44100 kr = 44100 ksmps = 1 nchnls = 1 ; Instrument #1. instr 1 ; Change a value linearly from 0 to 10, ; over the period defined by p3. kval1 line 0, p3, 10 ; If kval1 is greater than or equal to 5, ; then kval=2, else kval=1. kval2 = (kval1 >= 5 ? 2 : 1) ; Print the value of kval2 when it changes. printk2 kval2 endin /* printk2.orc */
/* printk2.sco */ ; Play Instrument #1 for 5 seconds. i 1 0 5 e /* printk2.sco */
Its output should include a line like this:
i1 1.00000 i1 2.00000
