STARISE...
i like the reverb,
but i think i know what you are after.
try this:
put your valhalla on it's on bus,
and use sends from each track, to the valhalla reverb bus.
either in the valhalla plug (i do not know this plug) or in the bus EQ section,
EQ the reverb:
roll off everything above about 5khz, and everything below 500hz.
then, re-set all the sends from the tracks, in the amounts you need.
see if that works.
great tune, really nice.
