ftmorf — Morphs between multiple ftables as specified in a list.
Uses an index into a table of ftable numbers to morph between adjacent tables in the list.This morphed function is written into the table referenced by iresfn on every k-cycle.
iftfn -- The ftable function. The list of values are expected to be pre-existing ftable numbers.
iresfn -- Table number of the morphed function
The length of all the tables in iftfn must equal the length of iresfn.
kftndx -- the index into the iftfn table.
If iftfn contains (6, 4, 6, 8, 7, 4):
kftndx=4 will write the contents of f7 into iresfn.
kftndx=4.5 will write the average of the contents of f7 and f4 into iresfn.
Here is an example of the ftmorf opcode. It uses the file ftmorf.csd.
