New version 2.0.2 : a test of glissando playback

• Jul 23, 2015 - 13:07

Hi there!
I've been waiting for this glissando playback feature for a long time, and finally there it is!
I tested it immediately, but it seems not to perfectly match my needs.(BTW It's still a great job for the developers. NICE!)
This is the test. I found out there are four types of glissando to choose from.
Chromatic: gliss by half notes.
White keys: gliss on white notes.
Black keys: gliss on black notes.
Diatonic: gliss for less notes, then play the second note directly.

I created the glissandi in different keys(C Major, bA Major)
Well, for the first three types they are the same. But when it comes to the last one, it plays the scale of the major currently using.
Eg. In C major it plays (CDEFGABC then the extremely high C, as I typed in the third beat
In bA major it plays (C bD bE F G bA bB C then the extremely high C, as I typed in the third beat
I was expecting this change, but this type only plays several notes, and then jumped to the high note.
I am hoping if there could be an option to play full glissando in a different key of major scale. Does anyone have solution or idea? Or is it possible to be improved in the newer version?

I've played some pop pianos and I've seen black keys glissandi, which seems not to appear often in classics.
Eg. black keys glissando in Reflection/by VK/in Taiwan/concert version

Chromatic glissandi can't be performed on piano but some other instruments (as I know)
The need for playback of full glissando in a different key of major scale comes from this:
Sea of Wisdom/by Daisuke Shimizu/Harp
Hard to hear the sound, so here's a part of the full score.

And...BONUS!! a bunch of glissandi


It isn't a "perfect" (if there is some "perfect" inside the music world) effect, yet.




Listen to the whit and black key glissandos in a slow tempo (like 10BPM) and compare to the chromatic, there are not the same.
The diatonic seems indeed wrong though

Hi Bowen, in the example you posted, you have a glissando spanning a key change. I haven't tested such a thing, and I'm not sure how it will work. My suspicion is that it would calculate the accidentals based on the first not of the glissando taking into account the key signature it is sitting in and the accidentals found previous to (or at the same tick as) that note in the measure.

It would be pretty difficult to support if the diatonic scale changes midway through the playback. Any thoughts?

Here is a glissando test. It looks like the playback does something funny when there are lots of notes in a small amount of time. For example. Screen Shot 2015-07-29 at 17.44.38.png

he first two measure include a dotted half not glissed to a quarter note. They seem to work correctly both in Diatonic and Chromatic mode. But measures 3 and 4 indeed behave strange. In these measure we have two quarter notes glissed together.

BTW, can you upload this score in Musescore format? or is it copy-written? I'd like to take a look at the glissando examples and see what I can make Musescore reasonably do with them.

May I ask how the glissando was created in the second and third images? I tried creating something similar in the past, but was unsuccessful.

EDIT: I'm not talking about the glissando line. I'm talking about the run of notes before it with the notes beams that trail off at the end.
