These work like the pseudo-isomorphic mappings above, but with the additional consideration of deliberately using non-coprime generators on all axes to take a MOS subset of their tuning systems. | These work like the pseudo-isomorphic mappings above, but with the additional consideration of deliberately using non-coprime generators on all axes to take a MOS subset of their tuning systems. | ||
=== 31edo (demonstrated to work) === | |||
For playing strictly in the Valentine 15L 1s scale (with no accidentals), it is possible to map just the Valentine scale by multiplying the antidiatonic mapping for [[16edo]] by 2 and treating note 31 as a duplicate note 0 (which never actually appears). [[Bryan Deister]] has demonstrated this in [https://www.youtube.com/watch?v=Aiihs4vqyfI ''16 tone improv (31edo)''] (2025). This gives back the range of just under five completely level octaves, and would even allow for division into multiple manuals. | |||

Continuing with the concept of only accessing every other note of [[31edo]] (again with a hidden note 31 that duplicates note 0), rotating the [[Valentine]] [[15L 1s]] scale to run down-right (instead of right-up) makes for easy playing of diatonic-sounding phrases (although with a rightward generator of 6\31, this is actually more like [[Slendric]]), while in a fairly compact layout having a range of over five octaves which slope mildly upwards. [[Bryan Deister]] has demonstrated this in [[https://www.youtube.com/shorts/HicjaGSZ83U ''31edo prelude'']] (2025). | |||
