I am recording keyboards with the strings effect. also a piano effect on another track. should I double track the strings track and piano track and pan them equally apart from each other or should they be in the center? my guitars I have panned 100%L and 100%R. maybe strings would be like 50%L and 50%R and piano250% L and 25%R? I'm just throwing numbers out. or should I just record 1 track and keep it in the center? I don't want to pan 1 tack too much  or I feel it will throw it off balance.

Not sure what you mean by 'effect' I guess you might be referring to string 'sound' or piano 'sound'. Firstly are your keyboards hardware or software? Are they in stereo ie two outputs. I would start by recording any synth or keyboard parts in stereo. You will find many have nice stereo imaging already.
 
Panning them in the mix means you can either keep them hard L and hard R but also with a plugin like Cakewalk Channel Tools you have the option to narrow the images down as well.

I'm using my midi controller. with the TTS-1 sounds. yeah I meant sounds not effects.
 

I usually pan strings to the left and piano to the right.
 
Strings are usually stereo, so I use the Channel Tools plugin to shift them rather than the pan slider. Piano may or may not be stereo - mono for dense mixes where the piano is not a featured instrument, stereo for when the piano's a major component. In the latter case, it's Channel Tools to shift the piano to the right. This places the left-hand portion of the piano in the center and high notes that convey melody to the right where they'll be able to cut through better.
 
(For purely orchestral stuff, I prefer to pan violins, violas, cellos and basses in the traditional way: first violins hard left, then second violins and piano at 50%L, violas center, cellos and basses 50-100%R. It's an odd arrangement by pop/rock standards, having your main melody hard left and bass hard right, but it's how they've been doing it since the 19th century so who am I to question it?)

thanks a lot. that helps me out a lot.
 

This might be a stupid question but are my midi keyboards already being recorded in stereo?
 
 
 

Based on what you described above, you're only recording MIDI data from your keyboard, which is just note commands, not audio and therefore neither stereo nor mono.
 
Whether you get stereo depends on the outputs you select from the synthesizer that you've routed that MIDI to. When you select the input source for your audio track, the TTS-1 lets you choose from one of its four stereo outputs or from any of the 8 mono outputs that make them up (each stereo out is actually a mono pair).
 
This is the great advantage of recording MIDI: you can always decide later what instrument you want to drive with it, and how to route that instrument's outputs. So if you use the TTS-1 today for strings, and a couple years from now you buy an advanced string library, you can go back to the project and replace the TTS-1 with something better.
 
BTW, here's a tip: don't use Simple Instrument Tracks. Use separate MIDI and audio tracks instead.

It all depends upon the song, temp, how thick it is and how much space you want.  from what you said I'd go w/ Bit's bit and pan them opposite.  Keep it simple, and if the parts are writen that way it provides a nice balance and should set between the guitars.  That would leave the middle open for bass and vocals and lead.  Very traditional arranging - because it works.
