need help asap

no one ?

I don't use the sequencer of the FG at all, but I don't see anything magical here. He is recording just midi. The user manual and some help videos on youtube about sequencing in FG should do the job. Where is your problem actually?
If you use an external sequencer, you record a beat, you and up with a midi clip and you are free to copy it as many times as you want.
There is absolutely no need to record any audio at that point. Forget audio at this stage.

yea but how do u connect your g to the computer? midi or usb? and what do u do in pro tools or logic watever for it to be midi instead of audio?

You ca connect the Fantom G to a computer via USB-MIDI or by using a MIDI interface and the MIDI connection on back of the Fantom G.

These days most sequencers record MIDI or Audio, and you usual select the data type for the track via some menu selection.

I watched the video and there are some operations cut out of the video, like arming the track to record. SO don't consider this video like a recording tutorial. But.....there are video's out there, even using the Fantom G, on recording and playing back MIDI and audio.

You need to sped a little time watching these, reading the manual, then you can ask question on the forum.

Your current question is just too involve to cover in a simple forum response.

Note: if your not sampling (audio) on Fantom G, you are most likely recording MIDI. Both of which can be done effectively on the Fantom G. You can send MIDI over USB and with many devices also (Digital) audio.

If you installed the usb midi driver for the FG, you can connect it simply with an usb cable.
The rest depends on which sequencer you use. You should also try the forum for your sequencer. It depends also on whether you work on PC or Mac.
The FG should be in studio mode.
If you have properly setup the usb midi driver, I guess that in protools the Fantom G midi connection should be available for selecting in a midi track.
You have to create a midi track and set the midi input and output to the Fantom G. Try to search on the internet for a Fantom G patch list for ProTools. With that patchlist you can see right in your protools the name of the patches and when you select a patch on a miditrack in protools, it should automatically select the respective patch on the FG. In that way you have 16 possible miditracks where you can record 16 different instruments right from your FG as midi data. Once you create a clip, you can edit it, quantize, copy and do whatever you want.

yea i do gotta mac and i use logic more then anything for sequencing...

I use Logic as well. Like mojkarma said, if the driver for the G is installed, hook the G up to your mac via USB. In Logic create a new Midi Instrument. If you look at the library/media panel on the right in the arranger window, the Fantom will be listed. If you highlight that you will see the 16 midi channels of your studio set of the G. If the Roland G Editor is installed, you can actually open it up as a plug in. Create an instrument. Now, when you go into the channel strip to assign an instrument there will be a sub-menu at the very bottom that says Roland-Fantom G. Either way is a great learning tool. Good luck!
