Chromatic harmonicas tend to be significantly more expensive than their diatonic counterparts—with a typical chromatic harmonica selling at a price that is up to ten times higher than a simple diatonic harmonica. Chromatic harmonicas produced by reputable companies (such as Hohner, Seydel, [7] and Suzuki [8]) range between 70 and 700 US dollars.
The 64 Chromonica is a four-full-octave harmonica in the key of C. With 64 reeds on a plastic comb, it boasts an extra octave below the middle-C note, giving it an accentuated versatility.

Simpler electronic keyboards have switches under each key. Depressing a key connects a circuit, which triggers tone generation. Most keyboards use a keyboard matrix circuit, in which 8 rows and 8 columns of wires cross — thus, 16 wires can provide 8 × 8 = 64 crossings, which the keyboard controller scans to determine which key was pressed.

An isomorphic keyboard is a musical input device consisting of a two-dimensional grid of note-controlling elements (such as buttons or keys) on which any given sequence and/or combination of musical intervals has the "same shape" on the keyboard wherever it occurs – within a key, across keys, across octaves, and across tunings.
