Preview decks and Sample decks ("samplers") in Mixxx are identical to regular decks, they simply have a different purpose (previewing tracks or playing samples, respectively).
Any control listed above for :mixxx:cogroupref:`[ChannelN]` will work for a samplers and preview decks, just replace :mixxx:cogroupref:`[ChannelN]` with :mixxx:cogroupref:`[PreviewDeckN]` or :mixxx:cogroupref:`[SamplerN]`.

The :mixxx:cogroupref:`[ChannelN_StemM]` group allows you to interact with specific stems of a deck when a stem file is loaded.
M ranges from 1 to 4.
Some controls (like volume, mute, and VU meters) are shared between decks and stems, while others (like color) are stem-specific.

.. seealso:: There are some :ref:`additional global controls for samplers <appendix-mixxxcontrols-samplers>`.

I didn't get you exactly. Are you suggesting that explanation at the top suffices?
