One thing about effects:
Check out the manual's illustrated bus-flow things.
Tracks 1-4 will allow you to send to effects BEFORE they get to mixing level, the other tracks do not let you send to effects.
The basic concept is that you have a 'dry' signal that you can send to the effects processor-magic area. That signal gets doped by the effects and then gets back into the regular bus (i.e the 'total' mix that you are monitoring) afterward. Think of a car factory with a series of conveyor belts each building a series of different cars, and ultimately ending up with the completed cars coming out of the end of the factory on their own converyor. To 'send to effects' you are diverting one or more of these conveyors into a separate area (say, the painting room). The restriction is that the painting room only is painting red at the time, so you would only divert the conveyors that you want to produce red cars to the paint room at that time. After getting painted (the effects are applied to the signal) the conveyor eventually all flow into one (well, two really, one left and one right) and this is the 'finished car' line that spits out completed cars (i.e. the mix you hear through the monitors). I guess with more complicated equipment, you could have different tracks go to different paint rooms at the same time and have less time and use less rescources spent adding effects to individual tracks, one at a time.
You can also add the effects before sending them to the recorder, they will always sound like they were recorded, but you could send them to additional affects afterward also. Confusing enough?
You can record a track (say electric guitar) with distortion etc, and that track will permanantly have it, but playing with mine last night (the first night I got it home, so I am still very green), you can also record dry and add efects to the track afterwards.
BUT, I believe you can only have one set of effects going at a time, and all tracks that are sent to effects will have the same effects. So this means you can't give one track reverb and another delay at the same time. You could probably add effects to a track, while bouncing it alone to another track and thus process each effect with different effects, as long as you have room to bounce/add effects to each track one at a time.
This is how I understand the process to work, please correct me if I'm wrong
