if you are talkin about the sequencer, best way is to draw boxes an alt + drag em

to transfer from redrum rightclick an export, i dont remember the exact name of command :/

2
you create a sub for each sound

as i can understand you, best way is to rightclick on the mixer, an create it
the red knobs on the top is the amount of effect sent to your device, and you can have four on the mixer

if you need more effects, simply create a new mixer an repeat the process

there, a month later, but it cane xD
