--  
-- * description : 
--  
--  vco2 is similar to vco. But the implementation uses
-- pre-calculated tables of band-limited waveforms (see also GEN30)
-- rather than integrating impulses. This opcode can be faster than
-- vco (especially if a low control-rate is used) and also allows
-- better sound quality. Additionally, there are more waveforms and
-- oscillator phase can be modulated at k-rate. The disadvantage is
-- increased memory usage. For more details about vco2 tables, see
-- also vco2init and vco2ft.

--  
--

--  
--  vco2ft returns the function table number to be used for
-- generating the specified waveform at a given frequency. This
-- function table number can be used by any Csound opcode that
-- generates a signal by reading function tables (like oscilikt).
-- The tables must be calculated by vco2init before vco2ft is called
-- and shared as Csound ftables (ibasfn).
