Perhaps that is why an algorithm that sounds good at as big of a setting as possible may sound good, but as the size goes down, the combing gets worse? Would I be smart to fade taps out (so they drop out gradually) at small sizes? A tap spacing of 50-80ms at canyon size becomes 5ms in a smallish living room. Keeping the same amount of chorus becomes much more noticeable in a small size. A 50ms tap spacing would result in a 20 Hz peak which is nice and low. At 5ms it gets to be 200 Hz - mudfest.
Or should I be looking at changing the tap gains - rather than trying to get a smooth decay, try to reduce combing by alternating and modifying tap gains somehow? I've been adjusting them for a smooth decay at canyon sizes so far. I would think that alternating tap gain signs would change the combing but maintain the density - maybe to half the frequency? What about applying acoustical diffusor patterns to the tap gains, spacings, and signs? Those equations are pretty well known, and I think I have them in an acoustic design book I have somewhere.
