JS Splitter/Joiner steeper curves

[Rmn]

JS 3, 4, 5 bands splitter/joiner are greats, but it only have a 6 db slope.
I know crossover by rs-met, but it have some sort of phasing issues or latency.
FFT filter have an infinite slope, which is not convenient.
I didn't managed to set a crossover with ReaFir which pass the null-phase test.

Would it be possible to have JS splitter/joiner working in 6, 12, 24... 72 slopes ?

I've uploaded my Effects folder: https://drive.google.com/open?id=0B0...FJOb3lteTAybjA .

You can find there some 2band splitters(Loser's 72db splitter), witti splitter and more. Have fun.

Wow, that's what I call a library.
Thanks, I'll check that up, and let you know (I'll edit my post later).

Edit : I've tried some, loser's, apple's... they all seems to have a phase twist which look like a notch filter. The only true transparent band splitter is the JS one (crossover by rs-met seems to compensate the notch, which is not perfect, but still discreet).

Due to some algorythms/code I guess, band splitting requires sacrifice.
Maybe the JS ones are not really a crossover but very similar trick.

Anyway, thanks very much for uploading the scripts.
