On the Edit page, you can specify whether you want to preview and select an instrument when clicking on it, or whether you only want to select it and show its sound parameters.
To preview an instrument when clicking on it, deactivate the Mute Instrument Trigger on Editor button in the upper right corner of the Edit page.
Instruments that have multiple articulations play the standard articulation. For example, a snare can be played open, with a rimshot, or with sidestick. For preview, the open articulation is used. To trigger the other articulations, use the instrument pads.
To select an instrument and show its settings when clicking on it, activate Mute Instrument Trigger on Editor.
