Software
If you want to install the software ther eis no installation media included in the delivery and you have to download the latest version of the software. A manual is always useful but not necessary, just connect the keyboard and then start to use it but if you want use the macros, you should definitely check out the manual. The user interface is a little bit different compared to older Tesoro's products. Also this part of the product is more mature and it perfectly matches the keyboards sleek style. A nifty little feature is the possibility to imported and exported settings.
