Hello,

I am wondering why a tool always worked in other orchestras in this case doesn’t work at all.

I am referring to the following lines, starting from line 28:

k\_VCO1\_off invalue “VCO1\_off” ; offset freq

gk\_VCO1\_off tablei k\_VCO1\_off, giExp20000, 1

outvalue “VCO1\_off\_display”, gk\_VCO1\_off

In the header I have created the table:  
giExp20000 ftgen 0, 0, 129, -25, 0, 1.0, 128, 20000.0

It happens that the k\_VCO1\_off control doesn’t read the table giExp20000, so in the output I get the default values of the control, in the range of 0 and 1.  
It always worked in other orchestras, and I really can’t understand what’s the issue here.

Thanks for your support.

G.

i think the problem is that you mix up two ways of creating tables:  
in the orc header, you create two tables with ftgen and let csound  
assign a number to them.  
in the score, you create a lot of tables in assigning numbers directly  
to them.

the console output says:  
“ftable 100:  
WARNING: replacing previous ftable 101  
ftable 101:  
WARNING: replacing previous ftable 102”

this means:

- your giExp1\_2 table gets the number 101 from Csound but is then  
overwritten in the score,
- your giExp20000 gets number 102 and is overwritten, too.

you can assign own table numbers to ftgen, for instance:  
giExp1\_2 ftgen 1000, 0, 129, -25, 0, 1.0, 128, 2.0 ;TABLES FOR EXP SLIDER  
giExp20000 ftgen 1001, 0, 129, -25, 0, 1.0, 128, 20000.0 ;TABLES FOR  
EXP SLIDER

this works, but i would recommend not to mix the two ways at all, but to  
put all tables in the orc header ans let csound assign the numbers.

best -

Thank you Joachim, now everything is clear, I had not thought of this detail. I’ll set the tables in the header.
