Complete OM archive

Hello everyone,

I am looking for previous releases of OM. Specifically, I want to find a version where Finale-Export still worked for me. The earliest release I can find in the forum archive is 6.5. Any clue of when the function was changed and where I can find the previous OM releases?

All best,

Hi JC
To my knowledge there is no archive of earlier versions.
However, I doubt the “copy-paste” finale export (if this is what you are referring to – in OM5 if I remember well) would still work on recent OSes.
Today, MusicXML export is recommended instead.

Hello Jean,

Thank you for your reply. Yes, I found an old OM version and indeed the clipboard function to finale doesn’t work at all. Interestingly, save-as-etf still works, and to my mind at least, does a much better job at exporting rtrees than MusicXML. XML seems to interpret a tree as durations, so if one works with proportional subdivisions MusicXML heavily distorts the original idea. But it is good to know that save-as-etf does a good job precisely where XML falters. There is a bug however which is easily corrected. The first measure of a voice is omitted when opening it in Finale. I don’t know if this problem originates in finale or OM, but if one simply adds a measure in OM to the beginning of the voice all works.

On another note, I find it quite useful to export chord-seqs, voices and poly objects as PDFs directly from OM. I usually have to manually adjust the position of noteheads and stems in the final PDF. It seems that this is something that could be corrected in OM by locating fonts with greater precision as the current positioning (which only appears to be ok in the voice or poly editor) does not reveal the problems that appear once the music is exported to PDF.
I also wonder what the criteria for spacing the score representation in OM is. I suppose it is linear, but it seems to vary sometimes.

Hello Karim,

Yes, I’ve used your library before and worked with it again just this weekend! Nevertheless, I encountered some problems in lilypond which I wasn’t able to resolve. I have not been able to figure how to have a fixed width spacing for measures in lilypond. This is so I can have a strictly proportional spacing. If I understand correctly, one can have strict proportional spacing within a measure in lilypond, but the width adjustment from measure to measure is more complicated (i.e. I want a 4/8 measure to be twice as wide as a 2/8 measure etc.). It seems simpler to create these spacings in Finale (I’m using Finale 2011), unless you have any suggestions for lilypond?

Another idea that just came to mind while working: it is possible to have different tempi in a voice, the only way I can seem to arrive at this is by concatenating two different voices with different tempi. Do you know if there is a different way to assign tempo changes for specific bars?

And one final question I’m hoping you can help me with: I’m trying to simplify some fairy complex trees by rewriting them in different tempos. In order to figure out what the new tempo should be I need to know what the base subdivision is. That is, say we have something like ((1 4)((1(1 1 1 1 1 1 1 )))) and then another measure with ((1 4)((1(1 1 1 1 1 1 1 1 1)))), how does OM know that the first is 7 16th notes in the time of 4 16ths and the second 9 32nds in the time of 8 32nds? In order for me to calculate the correct new tempo, I need to now if 7 is in the time of 4 16ths or 9 in 32nds.

Any insights would be greatly appreciated.

All best,

jc

Dear Karim,

Regarding my last question, I’ve realized that my approach was wrong. All I need to know is how the measure is substituted, so it is a simpler problem than I thought. Almost there…

And I found out that tempo changes in a voice are possible. One can set the tempo slot for a voice as ((1/4 60) (((1 0) (1/4 52)) ((2 0) (1/4 60)))) for example, making the first bar quarter = 60, the second quarter=52 and the third quarter=60 again. Wonderful!

all best,
