Tuplet Bugs

• Aug 6, 2016 - 22:42

I am attempting to create a Black MIDI using MuseScore and I am making some progress. However, I have encountered two issues with regard to tuplets.

Creating a chromatic scale spanning all 88 keys of the piano over one to three measures would involve me using tuplets in pairs such as 15-14-15-15-14-15; 29-30-29; or 11-11-11-11-11-11-11-11.

Attempts to copy and paste such tuplets has resulted in one of two errors that is preventing me from copying and pasting the tuplets at all:

1. "Please select the complete tuplet/tremolo and retry the command"

The tuplets are already fully highlighted. I select the entire measure and try to copy it, but still get the error.

2: "Tuplet cannot cross barlines"

The tuplets are all within a single measure, and I am selecting a single measure to paste it in (clicking on the measure), yet I still get the error. I am having more trouble with this error.

One final note, I have found that glissandi do not work the way I want them to when it comes to a Black MIDI. The last note is held when glissandi are used, and that is not the sort of effect that I want.

I am using version 2.0.2. If anyone has any idea how to solve this, please let me know. I would appreciate it.

First, update to 2.0.3; it fixes hundreds of bugs.

Copy and paste of complex tuplets is still occasionally problematic, though - any case where the number of notes doesn't divide evenly into 480 and is off by more than we are prepared to handle. You might need to fiddle with the grouping of notes if you need to be able to copy and paste them.

As for glissandi, could you give precise steps to reproduce the problem you are seeing?

Thank you for the suggestion. I think I may have figured out the problem. I saw another post talking about 256th notes: //musescore.org/en/node/23473 -- and realized that MuseScore starts glitching when the note value is that of a 256th note and smaller. Such notes cannot be copied and pasted. This may also have contributed to the first error.

I did a test by creating a 255/128 tuplet in place of a whole note, and I was able to copy that, but I was unable to copy a 2/1 tuplet in place of a whole note. The smallest note duration of the latter would have a value of precisely one 256th note.

Since the Midi effect that I call "Chromatic Diamonds" needs as many as 392 notes (49 white keys within one 8th note) per measure, such an effect could not fit into one measure without corruption. I think that my best option would be to stretch one measure of the melody to cover two measures. That would expand the limit from 255 notes in one measure to 510 notes over two measures -- enough to create this effect.

Your question about the glissandi is difficult for me to explain. My first idea for Chromatic Diamonds had been to use glissandi. I used eight notes in an alternating A0-C8 pattern and connected them with glissandi. The resulting pattern on the Midi file looked more like a hexagon than a diamond (or rhombus). This pattern is best seen in a Midi viewer like Midi Voyager.

If you still have more questions about the glissandi, let me know. Perhaps I can try to capture a picture of it.
