Editing samples to create gog usable wave files

[sjames2]

I am interested in creating gog files prior to recording to make isolated drum tracks and by using the recorded drums, in aiding drum repair of inconsistant hits. by doing this i would have the exact drum sound and not much effort in repair. I have been finding very vague information in creating usable samples to be inserted in drumagog to create gog files. i am looking for what is required, how long the sample any specific timing involved, advanced tutorial in creating gogs or direct me to helpful information. I would be very interested in any information reguarding this subject. this software is amazing and can be utilized as not only a tool but a help for smaller studios that work with limited budgets.
