The software is not required for use, but is recommended to access all the features of the Vanguard K08 keyboard and is available to download from the product page. It appears as though the Sound Blaster Connect app is a unified software that is now used for many Creative products we have tested lately, including the Sound BlasterX Katana, the Sound Blaster iRoar GO, the Siege M04, and now the Vanguard K08.
There is a wealth of preset lighting effects, as well as advanced customisable lighting effects, however it isn't quite as intuitive as competing software (CUE/Synapse Chroma Configuator) which easily allows various layers, while the Sound Blaster Connect app only allowed two 'layers' to be used by selecting which effect you wanted to have, then by selecting 'custom' to add your own 'layer' over it. There was no way to select many keys at once while creating a custom lighting effect also as there was no drag to highlight box enabled within the software, making it rather time consuming having to individually select rows or blocks of keys at one time. The lighting effects are very bright, vibrant and render each colour very well.
As each key is also programmable, the macro software however is very easy to use, and records all keys presses including any mouse activity and button presses. You can also remap and assign various keys or shortcuts for convenience.
