Hello. I realize this is a question that involves Logic but is not entirely about Logic, but I'm hoping someone can help me. I compose/arrange in Sibelius Ultimate which then plays back the instruments in Logic Pro via IAC driver. It works fantastic and I love it! However, there's one issue I would love to resolve. I sometimes want to stop work in Sibelius and work out some ideas on my M-Audio Keystation 88 keyboard with just a simple piano preset. The keyboard is connected via USB to my Mac. When I go to the keyboard, and Logic is the app on my screen, it will usually play back the preset of the last instrument I was working on in Sibelius - could be drums or bass, for example. If Sibelius is the app on my screen, it will often enter the notes I'm playing on the keyboard into Sibelius, and overwrite a part. I would love my keyboard to simply maintain the sound of a piano sample and not interfere with the Logic set-up or Sibelius set-up at all. Does this mean setting up a separate virtual instrument outside of Logic? I've never done that. I do own Keyscapes, Omnisphere and other third-party software. Thanks for your help!
