Based on this technology, and another idea, I came up with this equalizer:
http://davepermen.net/D4L%20CrossFilter.adg
it has 3 gains, low, mid, high, 3 kills, again, low, mid, high, and the option to define where the low cut and the high cut is. it uses sweepable crossovers for low/mid split, and for mid/high split.
the other idea I've chosen was, using the gain of the utility twice, once for going beyond 0db (up to +6db), and once for going below 0db (currently -36db), and switching the utilities in the middle. that allows for 0db gain in the center, and is thus nice to midi map to controllers like my faderfoxies.
obviously, this could be tweaked much (i think -36db is too much reduction, now that i test it aloud), and it would be cool to balance the steepness of the -36 - 0 - 6 curve (now it's just an edge at 0db
but i think without max4live, there isn't much more than one could do except with much too much extra work.
hope you like it, or at least the idea, to give some inspiration to other rack-ideas.
