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.
