[MU4 Issue] G2 and D3 in Muse Sounds piano sample has noise

[cmaxreilly]

When the piano in Musesounds plays a low G in bass clef, it triggers a piano sample along with what sounds like a low cymbal.

Steps to reproduce the behavior:

1. Create a solo piano score
2. Activate MuseSounds profile
3. Write a G2 in the score
4. Playback will play a cymbal sound as well as the piano sound

Expected behavior: Notation of G2 on bass clef triggers a piano sample on the pitch G2 in a = 440 hertz. (specificity)

• OS: OSX and Ubuntu Linux. My buddy is also checking his Windows machine, so expect an edit.

I don't hear anything like this on my Linux system. Please attach your score (ZIP it so GitHub will accept it) and a screen recording so we can hear what you hear.

Hi Marc, thanks for getting back to me so quickly! Something is bugging out on my macos and keeping some preference menus from populating, so screen recording is broken on my machine. While I figure that out, I bounced the audio for my actual song and an example piece. The problems were there in the mp3 when I checked, so that should give you the information needed. Attached are the mp3s and msczs for your analysis.

[MarcSabatella]

I don't hear any cymbal in your scores or the MP3's. Maybe your speaker is blown, or there are sympathetic vibrations from something else in the room?

I do hear something, sounds like the piano strings to me (it's very subtle, I had to turn up my volume to notice it)

Fristover, that's a much better description thank you. It almost sounds like there was a penny on the string or something. Marc, figured out screen-recording, so here is this.

I also notice another problem now that I've been listening this closely. Sounds like the waveform for D3 was cut in a spot that made a bit of a pop, like when a sin wave gets cut at 90 degrees. Is that something I should open another issue for, or is it adjacent?

[cmaxreilly]

Update: At the prompting of a friend, I tested some different dynamic levels. It appears that G2 does not have noise at or below piano. D3 doesn't have a noise below pianissimo.

[cmaxreilly]

Update: F2 also has a residual noise. It also sounds like there is a whole octave of piano notes below G that need a linear fade or for the cut on the sample to be lined up with a zero amplitude part of the sample. If someone wants, I would be happy to make a list.

I can reproduce this, too, on Windows 10 Home N 22H2 (build 19045.3448). The issue first occurs with mezzopiano and becomes very noticable with mezzoforte. It is very pronounced on G2, but it also occurs less pronounced on F2. I find cmaxreilly’s description of a coin lying on the strings fits the sound very well.

I was looking at the spectrograph of a recording to find some pronounced frequency, but I couldn’t find anything obviously off. However, I think I have traced the noice to the 8–10kHz range (for G2).

I've noticed this on both Mac and Windows. Drives me absolutely insane.
