I am new to keyboards and I'm looking to buy something that will allow me to create background music for movies and strip/remix mp3's and music files. I am a knowlegable computer guy with piano lessons under my belt, and I want to be able to take a popular song and remix it with a variety of voices, in addition to creating original music. I like the S90 in that is has a large voice library and that I can also hook it up to my computer and sequence without having to use an expensive onboard module. It seems I can get the S80 or S08 on eBay for a lot less than an S90 new. And the Motif seems like too much for my needs. Anyone have any recs for which synth I should get for my needs? I've considered the Korg Triton, also, but I understand the Yamahas offer more. Any sequencer software packages you can recommend would be great too!
