When Mono Mixes are converted to Stereo on the Sienna, which send function is assigned to Pan?

When converting mono mixes to stereo on the Sienna, the odd-numbered send is assigned to pan. This is based on the standard audio mixing techniques where odd-numbered channels are typically designated for one side of the stereo field. By assigning the odd-numbered send to pan, it allows for effective distribution of audio across the left and right channels, creating that stereo image. This mechanism is essential for achieving an immersive listening experience, as it provides spatial separation between sounds, thereby enhancing the overall quality of the mix.
