I have recently downloaded GPO4 as a plug-in to enhance my work on Sibelius 6.2. I have managed to get everything working correctly, but my main problem is knowing what to do now. There aren't any recent tutorials for Sibelius users and I feel a bit concerned that Finale users will find Garritan more useful than those of us who use Sibelius. I am a musician who has very little music tech knowledge and would greatly appreciate any help in getting through some of the jargon. I have read numerous forum questions and answers, and have learned a good amount, but I don't know where to go from here. I have tested Reaper, but don't know how to integrate Sibelius or Garritan into it. I have a Yamaha P-85 keyboard which I have used purely as a replacement for my piano which is 3000 miles awy. Can I use this as a Midi controller? If so, how? My computer is an HP Pavilion dv6 with Windows 7, with Intel Core i5-2410M CPU, 6 GB of RAM, IDT High Definition Audio Codec Audio Interface and 64-bit Operating System. I have also downloaded LoopBe30 for a reason I cannot even remember. I've been warned on the Sibelius site that the learning curve is steep and will take time. Is there a book which might help an older musician get to grips with all of this technology? Or might there be some suggestions regarding basic equipment to get up and running. I compose music for children and want to get beyond using just Sibelius. I am spending hours trying to find answers and it all feels as though I'm opening Pandora's box. Many thanks for any help you may be able to offer.
