Issue type

Muse Sounds bug

Description with steps to reproduce

Download the score at MuseScore.org and follow it's instructions.

The score is also attached below ... but there's a chance it's not as recent as the score at MuseScore.org

What is the latest version of MuseScore Studio where this issue is present?

MSS 4.4.1

Regression

History in MuseScore 3.x:

• User type velocities provided expected playback, but of course that was not with MuseSounds. • Offset type velocities summed the values of note velocity and the current dynamic, but again that was not with MuseSounds.

Given the current "state of play" in MuseScore 4.4.1 I don't know how to begin to intelligently investigate if note velocity and dynamics behave and comport with each other in MSS4.4.1. As it stands ... sometimes a note just inexplicably louder. See the example score.

Regarding other MuseScore 4 instruments, I've mainly used strings and voice, and they have similar "note volume" unpredictability, as if MuseSounds development believes that random note volume "humanizing" provides convincing realism. But playback quality is important to me ... and inexplicable variances in amplitude are a nuisance I can't work around. The variance in pitch is equally disconcerting and I don't see how that mimics reality on fretted instruments.

I continue hoping to eventually engage with MuseScore Studio as solidly as I have with MS3, but alas and again, for now it's back to MS3.7 for me.

Operating system

Another regression is that with MuseSounds, "sff" and sforzando (sforzato) dynamics don't reinforce the dynamic like it is supposed to. They technically decrease the volume of "ff" or forte. I have to manually add accents and untick "Play" from sforzando dynamics (sf, sff), which is a lot of work when I retrieve a MS3 score, which did reinforce these accents without manual action, nd try to improve it with MuseSounds and I have as many "sff's" as I did with a score that I might attach later and put in a seperate issue.

@DmitryArefiev pls investigate

Continuing erratic playback motivated my investigation into Muse Sounds Nylon Guitar.

My original MuseScore 3 source score contains only Offset note velocity ... and no dynamics. And as of MS 4.4.1, all MS3 Offset velocities are converted to User velocity 64 on import open. Which would lead anyone to believe MuseScore should sound all notes at essentially equal volumes.

• NI's Picked Nylon version plays smoothly. And it includes all the Offset velocities imbued in MS3.7, transported to Logic Pro X via MIDI. (I used Logic for the comparison because MS3.7 doesn't support VST—or Jack—and because MS4 doesn't honor Offset velocities ... and I was unwilling to reconstruct them as User velocities.

• The Muse Sounds Nylon Guitar version has several spikes in amplitude, other swells, some truly odd "ping pong ball" sounds and such. And of course, it does note play Offset velocities, as they are entirely ignored.

Here's a link to a few audio examples I posted on .org. Those examples contrast Muse Sounds Nylon Guitar to Native Instruments Picked Nylon and there's a time-guide describing where the "ping pongs" occur.

P.S. I've started investigating the behavior of velocities relative to dynamics ... and will post at another time.
