Basically, been getting into splitting the freq's of some of the synths i've been using recently, but so far i've had to clone whatever channel i'm using, then route it to separate mixer tracks, this is caning my CPU, so i'm often forced to resample, and I hate doing that for number of reason, leaves you less freedom with what you want to do to the patch and its harder to ad variations of it later on in the track.
But last night it clicked that you can do the whole right click and "route to this channel only" thing, as you would if you were using send channels, but you can do it to more than one channel, then process each one as you would normally would. Like, low cut one and ditort an reverb, then high cut the other and compress or whatever.
Just made my life alot eaiser, probably a well known fact tho, but I hope it helps someone!

As you can see, got my main synth routed to channel 10, this is in turn routed to 11 and 12, each processed differently
