Thank you Wolf.
I'll research the larger Cranes' note chart. A larger instrument makes sense because of the need for the chromatics. Many hymns are in Db and Ab and I'd really love to play them straight off the dots and have some sense of organization.
(I have looked at the layout of the basic SA Triumph, hoping they were on to something, but saw how haphazzard the notes were. Several key notes were missing on the LH, and according to the chart I saw the button layout for the RH is also 'upsidedown', with the higher notes toward the handstrap and the lower notes on top! Hopefully the Crane will be a better fit.)
Thanks again.
