Locating C Piano Key
From “Locating C¨ in Music Theory for Electronic Music Producers
The pitch C will always be the white key to the left of a group of two black keys. […] No matter what kind of keyboard you are looking at it, or what kind of sequencer, the location of C will always be the same. The only difference is that when we look at our Piano Roll Editor, the C is under the group of two black notes (remember that left means lower on the piano), because the piano is laid out vertically.
Note
Eureka
Nonetheless, one ties the pitch to the key for ease in conveying that pitch. More accurately, “C¨ then refers to the expected pitch of a key labeled such. “C¨ is a relationship between a key and a pitch, rather than merely one thing or the other.

Middle C
From “Middle C¨ in Music Theory for Electronic Music Producers
In addition to the letter name C, there is a number. That number indications[sic] which C we are looking at. On a keyboard (depending on the size of the keyboard), we might have six or seven different C keys. […] Middle C is the C key that is right in the middle of the keyboard. Technically speaking, middle C is C4.
Simply spoken, conventionally, middle C is C4. To know how to find C more generally, refer to 20240901115917-Locating_C_Piano_Key.
Caution
There can be “some confusion¨ in finding C4 as smaller keyboards wherein the musical alphabet and its accidentals repeat only once or twice can have buttons that allow us to shift the auditory frequencies produced by those keys down or up (Allen 2018, 31). (However typically the default has C4 as the either at the beginning or start of that small keyboard.) Furthermore, confusion is exacerbated by “synthesizer manufacturers about middle C¨ as some “label middle C as C3¨ (Ibid).
