i was wondering whats a good program with lots of different sounds and synthesizers to orchestrate with my keyboard, also is battery great for making drum loops?
Edirol Orchestral. Wow, an amazing soft synth / sampler. It contains a complete orchestra. It responds to all 16 MIDI channels with different intruments / sections. I love banging on the Timpani with it.
Some computer based systems (Cubase, Sonar, etc) bring with them DXi VTS plugins that includes syntentizers. I like pretty much the TTS-1 that comes with Sonar. Also you can buy separate plugins, some even uses different ways of playing sytentized sounds, like the Steinberg Guitarrist. When you came down to software, there are ilimited options.
Are you looking for a realistic orchestra set? Garritans Personal Orchestra is one of the better known orchestra sample librarys. It's possible to create very realistic symphonys with it. The orchestrated music in CSI is done with it
