A control pad like Elgato's Stream Deck is used by many creators. The Stream Controller is the control pad that Razer wants to use.
The company is working with Loupedeck on a device that seems to be a re-badged version of the Loupedeck Live. You can use Loupedeck's software on Windows or macOS to modify the Stream Controller's features. The controls allow you to change settings on the fly, launch apps and even manage smart home devices.
The dial helps the Stream controller stand out. They allow for fine adjustment of certain settings, such as lighting and volume, so you can use it as an audio mixer. You can create your own actions with the help of the marketplace.
You'll be able to set up multiple control layout for specific purposes and map them to the physical buttons. Digital artists can use the Stream Controller for both work and pleasure since they can switch between different functions. You could use the Stream Controller to control music during the day and help you with editing at night.
The extra utility of the dial and other functions will cost you a bit more. The Stream controller is more expensive than the Stream deck. The device will be shipped this autumn.
