This articulation is a combination of pitch and timbre change that can be done by assigning control of tuning and filter to a controller, then activating that controller. Not really remembering that particular articulation among the pre-sampled articulations... but you can certainly program the Voice you are using to control what you need.

Control Sets within the VOICE allow you to assign the control of parameter (DESTINATION) Coarse/Fine Tuning and Filter Cutoff Frequency to a physical controller (SOURCE). The DEPTH setting will need to be set to taste.

In order to do this level of editing with a Motif-Rack XS you will need to use the Yamaha Motif-Rack XS Editor on your computer.

Let us know if you need additional help with this; in the meantime we will try to find a reasonably close example of this type of controller setup.
