Hello all,  Thank you for reporting how all your transposing systems
work.  My question [in 100426 MMDigest] was not related to the
transposing method as such but rather what to do with the expression
coding when in 88-note mode.

This particular piano has no pouch block cutoffs, meaning that a true
88-note roll will randomly trigger the expression system.  The piano
was made in 1923 and is electric only, with the (apparently only for
Australia?) transposing bar.

I really need to know urgently if that could have been originally
delivered like that or if I need to manufacture or obtain some pouch
cutout blocks or single block.

Does someone have a drawing or pictures of the inside of such a block?

Kind regards
Bernt Damm
