Dear all,
suppose we have 2 transposing instruments and a non transposing one. In
PMX the convenient way to obtain transposed parts is 1) typeset all the
voices in the tonal key (no transposition) with relative accidents (Ar)
and 2) insert transposing command only in the desired part (e.g: %2 K-2+3).
Advantages of this method: 1) it produces a correct midi file; 2) every
parts can be easily transposed in different keys.
But if we *need*, for editorial reasons, to print the score with the
transposing instrument typeset in different key, we have to follow the
trick proposed by Cornelius Noack (see his pmx manual, p.97), i.e., 1)
insert the inline tex commands needed to set different key signature for
the transposing instruments (setsign{n}{m}) and 2) typeset the
transposing parts 'as they are written, not as they sound'
Disadvantages of this method: 1) it produces an incorrect midi file; 2)
it's impossible to transpose those parts in another key.
I've found a *not so polish* trick in order to keep the advantage of the
first method when we need to use the second one, with the aid of the
abcpp preprocessor. Abcpp allows to define different note names and
conditional output. So we have to:
1) define a set of note names for the first transposing instrument (XA =
f, XB = g etc.) and another one for the second (YA = c, YB = d etc.);
2) set in conditional way a different definition of the same symbols (XA
= a, YA = a) so that if TRASP is defined the output will be transposed
and if not the output will not be transposed;
3) Typeset the transposing parts with relative accidents and in
different ways (XA, XB or YA, YB etc).
4) compile with the command
'abcpp -TRASP sample.pmp sample_tr.pmx'
in order to obtain the score to print in editorial way
5) compile with the command
'abcpp sample.pmp sample.pmx'
in order to obtain the score not transposed and
the extracted (if needed transposed) parts.
You can see a sample of the abcpp source at the end of this letter.
Disadvantages of this method: 1) we have to typeset transposing voices
in different and unusual ways; 2) we need a preprocessor.
I'm sorry for this long, pedantic letter in my unsure english. Here
comes my question. Is there a better way to obtain the same result (at
tex level, for instance)?
Regards
Luigi
