May I inquire as to how long you guys have been playing crane? I have slight suspicion
that the "comfortabilty" of Crane vs Haydn is mainly due to familiarity.
I've been thinking about this a lot -- relative advantages of the different systems -- and
I think it is possible to define some quantitative measures that define the strengths of the different
1) average distance of whole steps and half steps (half steps are bad on Haydn) i.e. does note proximity
relate to proximity of the keys playing those notes.
2) How many different fingerings do the major scales require -- regularity. Transposition should require the
least possible mental effort.
3) Density of the notes on a given area. Some regular layouts have duplicate notes.
I've been meaning to write something up on it, I hope to have some time before August. Since these measures
partly dependent on the layout but also on the piece you're playing (c e d c e d c e d all the time will work very
well on the crane) it should be possible to write a program that reads a standard midi file and outputs a score
for the different layouts.
Oh and the 180 keys is correct if you don't add the extra button to the (that's the one you have no place
for after 3 octaves -- so it should be every 35 keys an extra one on the side).
