YES! :-)
< Filter Bank and Equalisation options
<
< The Filter Bank part creates a lot of equally distributed resonance
< peaks - this is responsibel for the "woody" character:
<
<
< That's the part that is common to all string instruments, more or
< less.
<
< (Board 1 + 2, what I'm taking preorders for now.)
<
< The resonance control changes the height of the peaks vs. valleys for
< all peaks in common.
<
< The Equalisation emulates the frequency response due to body size
< (dimensions of the wooden body and volume of air, plus dimensions of
< the bridge). This is different for each instrument. The picture here
< s the equalisation I'm using for a Cello. This, and similar EQs for
< other instruments, will be on Board 3 (not specified yet).
<
< Boards 1 + 2 are designed such that you can also connect 40
< potentiometers to get a fully variable 40-band filterbank. :)
<
< If you do this (40 sliders anybody?), you don't need any extra EQing -
< you can simply draw the courves with the slider position.
<
< But I think a 40-slider filterbank is not for the faint of heart ... I
< just wanted to mention it. :)
<
< Part of the standard implementation, however: 4 toggle switches to
< thake out every fourth resonant peak (or 2 out of 4, or 3 out of 4),
< for special effects.
