tablexseg — Creates a new function table by making exponential segments between values in stored function tables.
tablexseg is like expseg but interpolate between values in a stored function tables. The result is a new function table passed internally to any following vpvoc which occurs before a subsequent tablexseg (much like lpread/lpreson pairs work). The uses of these are described below under vpvoc.
ifn1, ifn2, ifn3, etc. -- function table numbers. ifn1, ifn2, and so on, must be the same size.
idur1, idur2, etc. -- durations during which interpolation from one table to the next will take place.
Here is an example of the tablexseg opcode. It uses the file tableseg_tablexseg.csd.
