The Operating System of the HAMMOND SK series is constantly being updated, with exciting new voices and features with every release. These updates are FREE and easy to load into your SK. It’s also easy to save and load individual patches, entire setups with or without your library voices, and custom tonewheel sets. Start by watching the “Gig Start” video guide on the Sk-1 Product page here at www.hammondorganco.com. This will familiarize you with the basic workings of the Sk. Then go to the “Galleries” tab and the “Videos” option and watch the various “how-to” entries. We’ll be adding more and more videos to help you make your Sk the SOUND, the SOUL, the ONE!
