Synched circulating Sensi[19]

Sensi, or semisixths, the 78732/78125 temperament, has a good synched
tuning. Tuning 19 notes to this gives a circulating temperament;
however, trying to use it for meantone is questionable since the flat
triads do not confine themselves to remote keys but are spread all
over. It would certainly suffice to produce a different sound for
meantone.
