K-2 is Behringer‘s clone of Korg’s MS-20. Aside from screeching filters, K-2 also includes MS-20’s unique and quirky features, so this tutorial applies to both synths alike. In this video, I explain everything from the intricacies of hz/v and s-trigs, through to K-2/MS-20’s ESP and Track & Hold circuit behavior. The second part of the video includes 18 patch ideas, including a hidden third oscillator in the patch bay, creating a bitcrush/downsampling effect and a few ways to play the K-2 and MS-20 paraphonically
