see: i have a whole song, made with patterns in FT, but i want to record my guitar over the song... how can i do it??? how can i make a new track to record my song with the base i made in FT??
hope u understand and help

fruity loops isn't made for recording things

you have to export your track to a wav file and then import that track into an audio program like Cubase or Cakewalk

then you use that cubase/cakewalk program to record your guitar over the top of the drum track.

Well, in FL Studio 6 you can add an "Audio clip" channel (menu>channels>add one>audio clip), then add the guitar previously recorded to that channel.
To put it into the song select that channel by clicking on it, then go to the lower part of the "Playlist", click on it, then arrange tha clip, as you did with patterns but in this case you'll see the wave instead of a block, sorry if this last part sound confusing

this might be of help..............

particularly using the FL as a VST

Or... Launch cubase first, make a new project in it... Open Fruity loops and automatically they are connected.

Read about ReWire.

can i import a fruity loops project into cubase? and how do i do that?

No... You can't.

Read what DJSkygrinder wrote just before you... You need to either use FL as VST or run it alongside, using ReWire (virtually connecting the FL output to a mixer channel in Cubase).

actually you can record a track in FL if you have an ASIO driver for your sound card (f you don't have one, just google for asio4all)

You just pick the mixer track you want, go up to the input selector in the upper right corner, select your sound card and the input you are using, then hit the floppy disk icon at the bottom of the channel strip (it automatically comes on when you pick an input, but turn it off and back on) and you'll get to pick where you want to save the audio clip. Then just pick your starting point on the playlist, arm fl to record (hit the record button first) and hit play. You'll get a 2-bar countoff (typical) and it will start playing, recording everything that comes through that particular mixer channel you picked before to the wav file. After you hit stop, it writes everything to an audio clip in the lower half of the playlist.

DjSkygrinder's tip might be very very helpful to you since you'd be playing your song from FL, but recording to Cubase at the same time, just make sure your settings are set so you do not record WAV output but only Line or Mic in, whichever you use.

Then WillyDavidK is also right. I use FL Studio XXL Producer Edition and from what I've read only the producer editions of FL Studio is able to in fact record. Only thing is, I haven't checked it out yet or tried it properly.
What I usually do is kinda the same thing as DjSkygrinder said... I check my time signature of my songs first, then set it up in FL, use the record function to make my clicktrack / metronome, then I export it to a sound file which I open up in Wavelab, then I play this clicktrack back, while I play with it and record ONLY my guitaring to a seperate track. This will obviously only work if there is guitaring right through the song. In some cases, as maybe in your case now, you might have the entire song already made up in FL Studio, which means the easiest way would be to export the song as one track to MP3 or WAV, then open it up in Cubase or Wavelab, play it back while you record guitaring as seperate new track (check your settings), then here's the nice part... you can discard your exported track if you are happy with your guitaring, cos now you can go and add your guitaring's WAV or MP3 file into FL Studio as an audio clip, which takes you right back to having every single instrument at your disposal for mixing how you like it. Your guitaring's audio clip can be placed/positioned/lined up where you want it to be by moving it around in the bottom of the playlist. If you use an audio clip in FL I hope your patterns are all being used in the Playlist, then simply switch to "song" instead of "pat" (pattern) mode. And there you go.

I went into bit of detail, but its really not that much of a hassle trust me. It's like one of the easiest ways. Give it a go, you'll see. Hope it helps. 

OH AND YOU CAN DO AUTIOMATION IN FL STUDIO TOO, USING AUTOMATION CLIPS.

Just add an automation clip, then paint it in the bottom of your playlist by the audio clip, then move it so it goes over your audio clip, lengthen it, move all your dots etc blah blah the way you want it to go. Whenever you wanna move/touch your audio clip with the mouse cursor just select the audio button which is a little bit to your left, if you wanna work with the auto clip simply click the automation button.

Easy eh.

If all goes well and I get my copyright in place I'll be uploading one of my songs soon enough, where I did this in. And the only instrument in this song thats real is my guitaring, all other instruments are all done in FL Studio. It'd be my first go at this but I think its progressing pretty well.

I should just shut up, cos I can't say when this'll be, but I AM looking forward to getting some feedback. Thats now if I do not upload one I did ENTIRELY in FL Studio. Still busy with the lyrics though on that one.

Blah blah blah... this isn't about me, but it WOULD be good example to you. I hope I helped.
