KLAVAR! is porting to MS Windows a graphic music sequencer/notation program based on the easy-to-read KLAVAR music notation, without clefs, sharps, flats or accidentals. It was originally written in GFA Basic for the Atari ST. Earlier releases were also targeting Apple Mac OS X and GNU/Linux operating system but the effort had to abandoned due to the uncertain future of the development tools used.

User Reviews

  • I originally contributed to this project and I thank reviewers that spent their time evaluating this (long abandoned) program. However, I have to say that the owner of the original ATARI ST application did not ask for a design change, but for an exact porting of the application. It was never supposed to be a professional tool, just a toy to play with. Some bugs from third-party development tools at the time prevented progress until the work grounded to a complete halt and was abandoned. For something to write music in Klavar notation there is already a program (Klavarscript). It is freely available and full of features, but it is not open source.
  • I'm being fairly generous with three stars. This is like a prototype. I could write better in a week. In the discussion, someone complains about various issues that I noticed too - their comment is nearly 10 years old. This is just about the rock bottom of what you'd need to put some notes on a klavar staff and play them (if you're lucky, and apparently only from the beginning of the piece). That's idiotic. If you're adding notes, composing or transposing, you want to check the last bar or so, not sit through all the bits you already sat through all the previous times! Selecting a different tool often pops up a warning that the score isn't saved. No problem, I'll click yes and save it - only instead it wipes all the notes off the staff. I think it considers the operation I was trying to perform something that should only be done on starting a piece - but it doesn't care or warn you - so it sets that option and starts you off on a blank score. You lose your work. When you do save, you have to select the file you saved already, and then Windows goes through the standard overwrite check. Notes in klavar should have lines to left or right to show which hand plays that note, and this program has the cheap and dirty default of making everything 'below' middle C in the left and above middle C in the right, but that's hardly ever how you play the keyboard. There is, however, no simple way to direct the left-right thing other than, having put the note in, select it and use the "switch hand" option. Great, I'm just going to do that with a load of notes. It could easily be done with a drag from positioning the note head to the left or right, or several other easy ways. Which reminds me of another big lack - any kind of rubber-band or multiple-select tool to operate on a set of notes together. If you made a mistake and the last four bars should all be transposed, select each note (left click) and delete it (right click), and then click to recreate it where it should have been. You can transpose the whole piece, just not do anything to a group of notes, apparently. Yeah, 3 stars, definitely generous. Just take it down or finish it, don't waste people's time.
  • Thank you very much for the program released under a free open source license!
  • worthy to try...!
