The SH-4d’s mixer mode is incredibly useful, as it lets you not only change volume and panning for each part but also reverb, chorus and delay send values for each. Accessing the mixer is slightly more fiddly than you’d expect, as it’s two button presses as opposed to one: first press the Pattern button to access the Pattern page and then press Sound to access the mixer page. The four faders default to the volume levels for Parts 1-4, while the Timbre knob controls the volume of the rhythm part. The keyboard buttons also act as individual mute buttons for each drum sound in the rhythm kit, making it very easy to drop out the kick for those classic buildups. Buttons 1-5 also act as mutes for each of the parts if flicking down a fader is too much trouble. You can adjust the send values for each track by navigating to the appropriate level fader with the up and down arrows and then adjust those values with the second knob directly below the screen.
To mute, either flick the SH-4d faders or press the handy mute buttons for a quick option
