By taking the pitches of both chiralities corresponding to each diatonic mode, we obtain the achiral scale LSCSLMLSLM, where C = L − S, termed ''ambi-diasem'' (after ''ambidextrous''). It ensures that every "supermajor third" (2L + S) in the scale has both major tone-minor tone and minor tone-major tone steps available. This is a stretched version of the [[blackdye]] scale with the same step ratio (with the L in the "SLS" of blackdye made smaller). There are 8 ambi modes that result from changing an occurrence of SL and LS in it to SCS (on the same root as the original chiral modes). | By taking the pitches of both chiralities corresponding to each diatonic mode, we obtain the achiral scale LSCSLMLSLM, where C = L − S, termed ''ambi-diasem'' (after ''ambidextrous'').
