Dear list,

using some Signal Flow Graph Opcodes I experienced, that k-rate  
signals are not properly read in by inletk in my orc. I just can not  
seem to get it working for k-rate while it works perfectly for a-rate.  
What makes me wonder is the output in the output window:

*******************************************************************************
Csound version 5.13 (float samples) Jan 17 2011
[...]
Connected outlet 1:audio_out to inlet 2:audio_in.
Connected outlet 1:control_out to inlet 2:control_in.


[...]

new alloc for instr 1:
Created instance 0x2601ad4 of 1 instances of outlet 1:audio_out
Created instance 0x2601bf4 of outlet 1:control_out

new alloc for instr 2:
BEGAN Inleta::init()...
sourceOutlets: 0x0
sourceOutlets: 0x176bfba0
Created instance 0x2604070 of inlet 2:audio_in
Connected instances of outlet 1:audio_out to instance 0x2604070 of  
inlet 2:audio_in.
ENDED Inleta::init().
Created instance 0x2604198 of inlet 2:
instr 2: icontrol = 0.000

[...]

*******************************************************************************


For the audio output we do find notes of the creation of instances. As  
it comes to the creation of instances for inletk in instr. 2 it seems  
to fail.
I now wonder, what could be wrong. Have I miscoded something or is  
there a general error in the creation of a control-rate instance with  
inletk? Anyway - no control-signal is read into instr. 2. Maybe  
someone can confirm, that inletk is working on his .csd?

You will find my test- .csd below.

Best regards,

Jan Jacob

Thanks for your report, I will investigate this. I am the author of
these opcodes.
