Now that weÕve gone through what the algorithm does, the question becomes ÒWhy are we doing this?Ó
With careful thought to parameter settings, EQ Morph does an excellent job of simulating the resonances
of the vocal tract. A buzz or sawtooth signal is a good choice of source material to experiment with the EQ
Morphers. Set the Morph A>B parameter to 0%, and Þnd a combination of A Þlter settings which give an
interesting vowel like sound. It may help to start from existing ROM presets. Next set Morph A>B to 100%
and set the B parameters to a different vowel-like sound. You can now set up some FXMods on Morph
A>B to morph between the two sets of parameters, perhaps using Freq Scale to make it more expressive.
When morphing from the A parameters to the B parameters, A Þlter #1 moves to B Þlter #1, A Þlter #2
moves to B Þlter #2, and so on. For the most normal and predictable results, itÕs a good idea not to let the
frequencies of the Þlters cross each other during the morphing. You can ensure this doesnÕt happen by
making sure the four Þlters are arranged in ascending order of frequencies. Descending order is okay too,
provided you choose an order and stick to it.
