(sorry if this is a repeat ..)

I *think* I have modified these opcodes to utilise non-power-of-2
tables.  It runs the simple examples in the manual for table and
tablei (does not seem to be a table3.csd) but this is barely
sufficient.  I would appreciate some test programs that stress the
edge cases, especially the wrap cases.

Here's another example that stresses tables.  It creates a table with
sizes from 2 to 513 then tries to read every point in each table it
creates.



-d -n


sr     = 44100
ksmps  = 64
nchnls = 1
0dbfs  = 1

instr 1


isize = 2
imax = 513

until (isize == imax) do

icount = 0
itab ftgen 0, 0, -isize, 10, 1

until (icount == isize) do
  ival table3 icount, itab
  icount = icount + 1
od

print icount

isize = isize + 1
ftfree itab, 0

od

turnoff

endin



i1 0 1

While you are at it, it would be worth converting tablew too.
