			There are several ways to map [[porcupine]] temperament onto the [[Lumatone]] keyboard. This article uses the Porcupine[7] notation convention from [[Porcupine Notation]].

			The mappings pictured below are based on mapping consecutive porcupine generator steps (~160 cents) to adjacent keys going generally left-to-right across the keyboard.

			A completely different approach to playing porcupine music on the Lumatone would be to use a standard mapping for some porcupine EDO (e.g. the [[Lumatone mapping for 22edo]]) and learn the shapes of porcupine scales in that layout. For example in 22edo, porcupine steps go roughly vertically rather than roughly horizontally, thus requiring a lot of "wrapping around". But if you just learn the shape of a "porcupine tetrachord" that could be a fruitful approach.

New page

==Ultra-compressed==

This has the largest range of any mapping shown here (5 complete octaves), but the sequence of nearby pitches can be confusing. In particular, notes separated by the Porcupine[7] chroma (denoted by ^/v here) are not mapped to adjacent keys.

==Compressed==

This is a compromise intermediate between the "ultra-compressed" and "expanded" mappings. It covers 4 complete octaves, and the Porcupine[7] chroma is now mapped to adjacent keys in the "vertical" direction. The sequence of pitches is still not completely intuitive, however: the Porcupine[15] chromatic scale still zigzags back and forth leaping over keys, rather than proceeding in mostly the same direction. This is because the Porcupine[8] chroma (denoted #/b on [[Porcupine Notation]] - for example the notes A and Bv are separated by this chroma) is still not mapped to adjacent keys.

==Expanded==

This mapping has the smallest range of any presented here - less than 4 complete octaves - but its main advantage is mapping the Porcupine[15] scale to an intuitive zigzag pattern. In-between pitches always appear in-between on the keyboard, rather than off to the side.
