MOTM

Oft I had requested a fixed filter bank and now I see that it is one of 
the new panels.  yay!

I was reading the description, tho, and I'm not 100% clear on the 
behavior.  The desc says that it's not like a graphic EQ, but then goes on 
to state that all the knobs set at 10 sounds just like a wire. 

I was under the impression that filters were not flat, they created bell 
curves around their center frequencies, so not everything in the freq 
range was filtered equally.  So a FFB, with everything set at 10 would not 
sound like a wire (vs an EQ, which would), but would instead sound like a 
whole bunch of bandpass filters so that the center frequencies would all 
be emphasized and the sound would be colored by passing through the FFB.

So, colored or not?

Also, anybody in the SF Bay Area planning on ordering one?

thanks,
celeste

Well, I over-simplified. More like a 'rippled wire' response. I'll post some plots tomorrow. The
point I was trying to make is that the behavior if the MOTM-450 is *not* what most people are
used to (EQ cut/boost). It doesn't cut OR boost.

very groovy!
a mp3 of some white noise running through it would clear things up too :)

Hm... well, maybe I'm a clueless idiot when it comes to modular gear, but
if it doesn't cut or boost, what DOES it do?

No, no, not clueless! Paul is sometimes, ehem, *obtuse*.  Each 
filter in the bank pass only a certain range of frequency. It 
neither boosts nor cuts that frequency range.  It does in a 
sense 'cut' all frequencies around it; it's a band-pass filter.  The 
whole thing is a collection of band-pass filters tuned to different 
frequencies.

Except the low pass and hi pass knobes: these filters are low pass 
and high pass respectively.

Hope that clears it up!  And I further hope I got the explication 
correct...

*Very* coloured.
Even without pots ( = all pots at max) this would be a
usefull device to "colour" a sound. And the colour
is "Moog". With the uVCF and the Filter Bank you have
two of the most important pieces to create that "Moog
Color".

(I'm regularly running my CS-50 thru the prototype,
and it's astounding how much it can change the character
of an instrument.)

cut AND boost. (;->)

There's a lot of weird interaction between the channels, which gives
the desired coloration effect.

Hmm, what kind of wacky doublethink have you got there...?
