Fix the sample rate for the Genesis React Pro.
Fix the sample rate for the Genesis React Pro.

This model doesn't support a 2 second sample rate. It appears the
possible sample rate values have been shifted by one to map the value
zero to a 15 second sample rate.

To avoid any trouble with possible out of range values, the index is
shifted in a circular way.
