You will want to contact Yamaha for information on a supported hub or switch for use with your Yamaha mixer. There may be a virtual soundcard that needs to be installed on your system as well. Yamaha should be able to help you with that part of the setup.
Inside of Studio One, you will want to go into Studio One>Preferences>Audio Setup and configure your audio interface. You can then manually configure the I/O setup for your inputs. Here are instructions for manually configuring the I/O in Studio One.
Software I/O Channels
In most recording applications, audio Tracks directly use your hardware audio device’s channels. In Studio One, there is a layer of software I/O (input and output) channels between your hardware audio device channels and your Tracks. This setup affords many advantages over the traditional method.
For instance, let’s say you produce a Song in your studio, using a multi-channel interface, then take your Song file to your friend’s studio, where you use a different audio interface. Simply connect your friend’s hardware audio device channels to the correct software I/O channels. When you get back to your studio, the original I/O configuration for the Song is automatically loaded for you, as if you never left. You can do the same thing if you need to open the Song on your laptop using its built-in audio hardware.
This is possible because Studio One stores I/O configurations with your Song, per computer and per audio device driver, ensuring that your Song remains highly portable and is never “broken” by changing audio devices.
Audio I/O Setup Menu
Each Track in a Song receives a signal from an input source and routes to an output destination. The input sources and output destinations made available to each Track are determined by the software I/O channel configuration created in the Audio I/O Setup menu. To view this menu and set up a default I/O configuration for each Song, create a new Song by clicking on Create New Song in the Start Page and navigate to Song/Song Setup/Audio I/O Setup.
