RE: something interesting from waldorf
to integrate the analog filter, an extra set of ADACs had to be introduced into the filter section of the algorithm, which means essentially you digitally create an oscillator sound, then you have a choice to either A)convert it, then send it through the filter, then back into the filter router, then convert it and filter it again, and then to the amps and effects parts of the equation chain, or leaving it digital at all points in the routing. At either of the possible conversion points in the filter routing the signal can be left digital, and just filtered digitally instead. Implementing the filters per voice took a redesign in the entire board, not simply for space and allocation, but because of implementation per voice, and not just at the output. It was a royal pain in the ass to make this system as flexible as it is, so hats off to Waldorf for doing it the way they did, cuz it works.
The AFB could not be implemented this way as a retro fit for the Q/Q Rack, because you have to take the signal out of the CPU then send it back into it per voice to do what the Q+ does. That means and extra set of convertors in the chain from the outset of the signal generation.
Personally, I see the AFB16+ as a flop in the making. Retail is $2500 US. EEEEKKKK!!!!! For that price, spend the extra thousand, and get the 32 voice synth engine, nice keyboard, control surfaces, sequencer, and effects thrown in as well, if you're so desperate for the Waldorf VCF sound.
