Help with LoopIII and Loop iv

[cameron street <cameronstreet@optusnet.com.au>]

Ok since installing loopIV ages ago, i found everything quieter,
but the limiting is to much for me.
I reinstalled LoopIII today to compare. and i prefer having more 
headroom.
but without all the new cool upgrades that i'm now used to.
My setup sonically is quite complicated, i use the bass as a 
ElectroAcousrticResonator,
so i use other instruments through my bass, to cut a long story short.
nothing new, but i found getting sounds to cut through ontop of a loop 
more difficult since loopIV.
Help please
is the limiter removable or adjustable.
