A keyboard that is isomorphic with the syntonic temperament, such as Wicki's keyboard above, retains its isomorphism in any tuning within the tuning continuum of the syntonic temperament, even when changing tuning dynamically among such tunings. Plamondon, Milne & Sethares (2009), Figure 2, shows the valid tuning range of the syntonic temperament.
