Hello,

Is there a more efficient way of defining the following simplified udo that
I use as an array of tables ? I need to use several similar udos and I don't
want to load each table in the memory.

opcode Array1,i,i

inumber xin

;default table
ireturn ftgentmp
0,0,16,-2,0.25,189.0,0.5693443418,-170.0,145.0,-545.0,1150.0,170.0,745.0,-55.0,395.0,-520.0,-1130.0,-1140.0,370.0

if inumber == 0 then 
iretour ftgentmp
0,0,16,-2,0.25,391.0,0.1453588009,295.0,450.0,605.0,-1115.0,-1175.0,-570.0,825.0,365.0,205.0,-135.0,-290.0,-35.0

elseif inumber == 1 then
ireturn ftgentmp
0,0,16,-2,0.5,814.0,0.7337720394,1140.0,-730.0,180.0,740.0,545.0,895.0,305.0,435.0,-310.0,910.0,-1010.0,-735.0

elseif inumber == 2 then
ireturn ftgentmp
0,0,16,-2,2.75,795.0,0.6835337281,-1075.0,-140.0,-210.0,815.0,200.0,-610.0,50.0,-25.0,550.0,-585.0,630.0,370.0

elseif inumber == 3 then
ireturn ftgentmp
0,0,16,-2,3.0,824.0,0.1787540019,-350.0,-355.0,1155.0,-370.0,295.0,550.0,-995.0,-525.0,285.0,-925.0,-365.0,-140.0
endif

xout ireturn

endop

Thanks

I think the tricky part of what you're wanting to do is only loading
each table on demand.  Even in another programming language like C or
Python, loading an array on demand is going to involve some ugly code.

I'd probably just code to load each table into memory if the tables
are like these (16 length), and put the table numbers themselves in
another ftable. However, if your other array tables involve very large
data (long waveforms); is that the case?

My array tables involve small data, but I plan to use a large number of them.
I'm designing  a csound installation that should run for hours and the array
tables provide pitch patterns, duration patterns, filtering patterns... So
far, my udos work well with a small scale installation but I want to be sure
that a bigger installation will run flawlessly and that the lack of memory
won't be a problem.
That's the reason why I don't want to load all the tables in memory but only
when they are needed.

How much memory will you need, and how much is available on the machine?

Usually, I find, a contemporary personal computer has scads more
memory than Csound uses. Suppose you have 2 gigabytes available in the
heap (this would be the case if you have 4 gigabytes or more on the
machine). Then you can have 30,000 64 kilobyte function tables. I'm
guessing your tables are smaller, and you don't need that many. With a
few thousand tables you can just forget about it.

Regards,
Mike

Thank you both for your advice. I rewrote my routines and found that it was
easier to load all my tables at once rather than load them at will.
