Bank-Switching Command Set

The US-224 has two switches that allow the user to select the bank of application channels that is addressed by the four channel-strips. For example, an application with 32 virtual tracks would define eight banks of four channel strips each. The Bank-L and Bank-R switches let the user quickly shift the control surface to address any bank of four channels. There are two LED's adjacent to the Bank-L and Bank-R switches, which indicate that pressing the button will cause the application software to switch to the next lower or higher bank, respectively. It is OFF when there are no further virtual fader banks available in that direction.
