I am trying out global k-variables, and made a simple example, see below. I
expected the k variable "gktest" to add vibrato to my poscil, but it
doesn´t. It works fine if I define it as a local variable. Is there a bug,
or have I misunderstood this?





sr 	= 44100
ksmps 	= 10
nchnls 	= 1
0dbfs  	= 1

gisine		ftgen 0,0,2^12,10,1
gktest		lfo 30,2,0

instr 1
asig poscil 0.3,400+gktest,gisine
out asig
endin



i 1 0 4

I tried to put the gk in another instrument, see below, but it doesn´tt work
either. When I read in the Csound book about global csound instruments, for
example nr 1805 etc page 356, it seems to me that I should be able to define
a gk variable within an instrument and use it in another?





sr 	= 44100
ksmps 	= 10
nchnls 	= 1
0dbfs  	= 1

gisine		ftgen 0,0,2^12,10,1

instr 1
gktest		lfo 30,2,0
endin

instr 2
asig poscil 0.3,400+gktest,gisine
out asig
endin



i 2 0 4

yes, but you need to run instr 1, otherwise there is no signal being generated.

Here's the deal

1) outside instruments, in the global space, only i-time code can be run,
and that includes running "init" on global k-rate variables (it is i-time)

2) you can fill global variables inside instruments. By doing so, you are
creating them. But for the signal to be generated, you have to run the instrument

3) you can consume global variables in any instrument, but the variable
needs to exist (ie. have been declared somewhere) beforehand

Ok. Embarrassing. Thank you for your help. It works fine now.

Your example only turns on i2, but not i1, so it is not actively
writing anything.
