Patent 9608747 was granted and assigned to Yamaha (yacht) on March, 2017 by the United States Patent and Trademark Office.
In a digital mixer, when a patch of a certain channel is changed, values of parameters of one port which has been connected to the certain channel is applied as parameters of a newly connected port, thereby enabling to hand over parameters of the one port which have been set for the certain channel. Further, when a newly connected port is already connected to another channel, the digital mixer asks the user whether or not to apply the parameters of the one port.
