For true high end FX(Analog effects/complete analog circuit
(Check the desktop evolver=synth FX /Filter.
Akai MFC 42 Analog filter and ofcourse Shermans Filterbank.
this a small selection, there are loads of true high end analog effects that leave pioneer and korgs far far behind .
i believe you own a Xone ?? , maybe you should look @ TC electronics M300 also
It,s a multi effect !
And to beef your sound up,............ever thought of a Tube Channel/
It gives tube warmth and harmonics to your signal ,it can sound pleasantly warm but also heavy/raw.
when you route your Xone,s output through http://www.artproaudio.com/
Check TPS II tube preamp with instr.inputs(it,s in the collum of microphone pre-amps, but dont let it fool you , it,s not only and exclusive for mics)http://www.joemeek.com/twinq.html
is also a very very nice dynamics processor that beefs your sound up !
And then ofcourse you can chain the most wicked guitar pedals to achieve a weird sound.
for instance :phaser to EQ to Ring Mod to Wah
Try not to search in dj oriented Fx only , cause they wil always run after pro FX .
Just a tip !
