I got this DVD to help me navigate my TR-61. I was a bit apprehensive about buying a DVD for another synth, but my understanding was that the LE and TR were mostly identical, bar a few things like patches and RAM. Suffice to say I m not disappointed! TR/LE compatibility: The two synths look and sound the same, and once you get past the LE being white, you ll soon wonder what the other differences are, if any. The interfaces are identical: menus, functions, procedures and so on, so applying what I d learnt to my TR was problem free. Some bits are complicated as you d expect with the masterclass title. Yet David s explanations are easy to follow and concise. The enlarged on-screen display makes following practical demonstrations easy and uncomplicated. M last Korg was a T3, so programming the TR was really intimidating and the manual unhelpful. Would I recommend this for a TR user? Yes! Definitely. Beyond basics, I wouldn t be able to do much without this tutorial.
