Dear mutex subscribers. Some of you may have noticed that I have recently published two new versions of a triosonata by the swedish baroque composer J. H. Roman typeset and published by Don Simons some years ago. The difference between Don's and my version of the origininal work in g minor for two oboes and b.c. is mainly that I have transfered Don's pmx code to separate mtx sources for each movement and that I have added an extra staff with my own realization of the figured bass. The c minor version, however, is an arrangement for two treble recorders and b.c. transposed a fourth upwards to c minor. I didn't need to do any further changes to have the solo parts fit within the range of modestly skilled player's treble recorders, while quite a few sections of the basso part needed octave changes caused by the unusual wide range of the part in the original work from C to f' - with the F cleff: between the second lower ledger and above the second higher ledger. In order to do the necessary editing of the transposed bass part and a realization from scratch of the figured bass I needed to transpose the mtx source files from the original to the new key. For that purpose I have created a perl script utility trmtx.pl that identifies all mtx note words and calculates their new transposed value. This utility has been published in the GMD mtx software section (http://www.gmd.de/Misc/Music/musixtex/software/mtx/trmtx.zip). As stated in the accompanying readme file a proper functioning of the transposing utility depends on the mtx coding using solely relative octaves (+ -) and accidentals (Ar). I encourage interested mtx hackers to download the utility, use it and report any problems to me.
