Instruments with split keys granting separate enharmonic pitches never gained popularity among keyboard players

Evidence

A number of keyboard instruments have been experimented with that had split black notes (in either direction) to provide access to their enharmonics, giving C# and D♭, D# and E♭, F# and G♭, G# and A♭ and A# and B♭—for example, the McClure pipe organ in the Faculty of Music at the University of Edinburgh discussed by Padgham (1986)—but these have never become popular with keyboard players. — David M.
