Hey hey,
I'm working on a bigger orchestra for live use, with quite a few configuration 
options. These options can be saved to ftables and lastly files anyway.

In my instruments: does it make a great difference whether I use tab and tabw 
to access/change these values or first write to k-rate variables, which only 
get transferred to ftables, when it's time to save?

No index interpolation and tablesize checking is required, so tab and tabw can 
always do the job "safely".

Best wishes,

Jeanette

Use of a k variable is certainly more efficient than a cal to tab/tabw as it 
requires an opcode call and a t least one addition  a range check and a 
indirection.  Not measured it though.  You can do so with the timing 
opcodes if you want to quantify it.

At least tat is my opinion

I'd rather take that. I vote your Csound opinion higher than I'd rate my
knowledge of it any day. :)

Thanks and best wishes,
