Subject	[Csnd] if statement and turnoff/turnon
	Hello. I am using an if statement to turn on and off an instrument. It doesn't seem to be working however - what happens is that if I compile with the control set to "on", it stays on - if I turn it "off", it turns the instrument off, but then I can't turned it on again without recompiling. Also, I am having trouble in instrument 2 with initialisation - could that be the problem? everything works fine if I set the table numbers for tablewkt in my controls beforehand, and compiles without error but if I don't set my controls, I get this - "PERF ERROR in instr 2: Table write k rate function table no. 0.000000 < 1" - I thought my INITs were taking care of that, but apparently not. I have a feeling I am just not conceiving of something correctly, but if someone could have a look, that would be very helpful. The code to turn on and off the instrument is here - the instrument being turned on and off is to record into tables - I have activated it in the score section for the same length as the first instrument : instr 1 a1, a2, a3, a4, a5, a6, a7, a8 ino gkRecord chnget "k_rec" gkRecord init 0 if (gkRecord == 0) then turnoff2 2, 0, 2 elseif (gkRecord == 1) then turnon 2 endif <code fragment> Here is the instrument: instr 2 ; Recording instrument ktabrec1 init 1 ktabrec2 init 2 ktabrec1 chnget "k_rec1" ktabrec2 chnget "k_rec2" kBuflength chnget "k_g_buflength" kFileLength tableng giFile kFileMasterlength = kBuflength/kFileLength kRecMode chnget "k_rec_Mode" a7 inch 7 a8 inch 8 ;Record phasor inputs afilrec phasor sr/kBuflength afilrec = afilrec * kFileMasterlength; * kBuflength tablewkt a7, afilrec, ktabrec1, 1 tablewkt a8, afilrec, ktabrec2, 1 printk2 kBuflength printk2 kFileMasterlength endin

	I guess the problem with your instr 1 is that 'turnon' is i-time only. It won't work at performance time. Try using schedule or any of the other instrument control opcodes that works at performance time. In the second instrument, initialising the k-variables does not help because the opcode chnget is setting them to another value (0) straight after. Victor On 31 Oct 2009, at 14:36, J wrote: > Hello.

	Thank you for your response! That makes perfect sense in the case of Turnon - I will look into using schedule instead. In the case of the second instrument, is there a way around this? So that a setting can be initialised to a value which can be changed by a chnget after it has been initialised?
