Where can I get some guitarbt is losing some because of a lawsuit..
get a drumm VSTi and a Bass Vsti and make your own. stop being lazy.
what are those?
virtual instrument plugins, you insert them into your DAW and control them with MIDI and they make whatever sound you need (depending on the plugin, there are some made for bass, some for drums some for various synth sounds etc.)
I think I understand could you tell me some program for them?
Reaper is a good free one to host them in and write out the midi parts. (you can also take the MIDI parts from GP files of songs you like if you have GP) and you'll have to look around for the different VSTis
