midi file import

2009-09-09 04:15 pm

Hei, I have a slight problem which I have been unabled to solve. I have been given a midi file of a choir setup (SATB) together with the piano score etc. for our choir. This is over 600 bars long and there are 8 channels (or staves in NWC). The problem encountered is that every bar in every stave has it's own key and time signature - is this normal with midi input? and how can I remove all of these which are unneccesary as I only want time or key signatures in bars when there are changes. I know that I can remove these individually for each, but what a job! I thought that maybe there would be some form of editing function when the midi file was imported, and maybe there is, but I can't find it. Can anyone help please as I only have a short while in which to sort this out. The composer/arranger died a couple of weeks ago so unfortunately I can't ask him for help!

That was done to keep you from using a program like NWC.

If you want to export it into a nwctxt file you can take out the extra stuff with a text editor. To do it in NWC for each staff:

Cntrl/F and check "By Category" and select Time Signature or Key Signature
If you want do delete it, press Delete Key
Rock between the F3 key and Delete Key till end of staff. To skip a real object, press F3 w/o Delete.
Repeat for extra objects on each staff.

Hope this helps.

Noteworthy Composer is quite clever.

You might find that if, having imported the Midi File and found all those extra time signatures, you save it out (or export it) as a Midi File, Noteworthy strips out all the superfluous ones, so that when you then re-import it the File is OK.

Indeed it is. If you export this mess:

Code: [Select · Download]

!NoteWorthyComposerClip(2.0,Single)
|Clef|Type:Treble
|Key|Signature:F#
|TimeSig|Signature:1/4
|PerformanceStyle|Style:Tenuto|Pos:9
|Rest|Dur:Whole
|Bar
|Key|Signature:F#
|TimeSig|Signature:Common
|Rest|Dur:Whole
|Bar
|Key|Signature:Bb
|TimeSig|Signature:Common
|Rest|Dur:Whole
|Bar
|TimeSig|Signature:3/4
|Key|Signature:Bb
|Rest|Dur:Whole
|Bar
|TimeSig|Signature:3/4
|Key|Signature:C
|Rest|Dur:Whole
|Bar
|TimeSig|Signature:6/8
|Key|Signature:C
|Rest|Dur:Whole
|Bar
|TimeSig|Signature:6/8
|Key|Signature:Bb
|Rest|Dur:Whole
|Bar
|TimeSig|Signature:AllaBreve
|Note|Dur:Whole|Pos:0
!NoteWorthyComposerClip-End

It reimports nicely.

If you use this method, insert a Performance Style of Tenuto at the beginning of each staff.

Hei again fromt the poser of the original question, The solution to the midi file import problem was as suggested. I created an NWC file which I then exported as a midi file. On importing this midi file again I "got rid of" everything that was superfluous, ie all of the key and time signatures which were not necessary. Thanks for the help.

Thanks for the help.

Thanks for the feedback. Some of the questions posed here require many minutes to posit a cogent answer, even for posters that have used Noteworthy for a decade or more. It helps to know when it has been worth the time and trouble. Kudos to MusicJohn. I was in the middle of a very labored response that was overtaken by his brilliance.
