MOTM

Since Yahoo is losing my posts into some black hole, let me post this again.

Now is the time when I must yet again remind those involved in this thread
that everything you ever wanted already exists as long as you don't need it
to look like an motm module.  Analog Systems and Doepfer have all kinds of
stuff, from the AS Vocal Phase filter to the Trautonium filters.  Cynthia's
bandpass filters modules looks useful if you don't need VC.  Cwejman now has
a fully voltage controlled analog parametric EQ.  The EAR group that Peter
Grenader is involved in also has something similar.  Regular old graphic and
parametric EQs can be turned into filter banks with the invert one channel
and mix method.  And then if you really want to go wild, pick up a used Nord
Micro Modular dirt cheap, and you can patch up and create variable filter
banks and EQs with all parameters controllable from midi and with analog I/O
to patch into you motm.  There's your AudioEngine right there.

uses 15 and 31 band equalizers to synthesize resonant cavities.<<

I usually use EQ within a patch, but I use lowpass and bandpass filters, and
parametric EQ to get resonant cavity type stuff since those allow strong
resonances to be set.  Even the motm 410 gets used at times in there.

Or IMPOSSIBLE to do in analog.


The 450 fixed filter being shelved seems more to do with Paul S. adhering so
stubornly to those expensive pots and knobs and whatever else, to the point
where anything that uses more than just a few of them becomes so impractical
in terms of price that nobody wants to buy it anymore.  The original
estimated 450 kit price was $190, then it went to $260, then to $380, then
to over $400.  That's why there aren't many potential customers for it.
Maybe for something like the 450 it's time to drop the seeled pots and other
overpriced stuff (I still remember the thread about suppliers screwing MOTM
on part prices, which gets passed on to us) and do it in a practical way.
If you buy a 15 band Doepfer fixed filter bank for $160 assembled, but an
MOTM 8/10 filter bank would cost over $400 in kit form, something is wrong.
