Muse sounds ranges

• Dec 2, 2022 - 19:40

I'm noticing multiple instruments that don't have the ranges needed. Clarinet doesn't have a Clarinet in A, and so can't play quite the range required for many common pieces - like Mozart's famous clarinet concerto. (though that was originally for basset clarinet, which there extra special isn't the range for)

The Flute 1/Flute 2 cannot go below a c; but b-foots are quite common on flutes now.

Looks like Contrabasses do cover the possibility of having a range extender

I wonder why exactly these sounds are limited by range. Eb clarinet sounds no different than Bb sounds no different than Bass, so why differentiate? There are clarinets in 13 different keys I can think of off the top of my head; that seems like an enormous amount of work. What is the thinking on this?


Hello! This is a known issue indeed - see I think the plan is to find a way to "scale" the frequencies to extend the ranges of the instruments beyond what was originally sampled, rather than try to record additional samples. Hopefully this happens before the initial 4.0 release, but if not, I'd expect it soon thereafter - it's identified as a highest priority issue.

I'd disagree, though, that Eb clarinet sounds no different than Bb or bass clarinet - they have very different timbres even at the same pitch. Bb and bass. But, Bb and A clarinet sound significantly different only right around the break (eg, B4 on a Bb clarinet is Bb4 on an A clarinet, and those notes sound very different). So probably it just wasn't worth the extra time / effort / expense / storage space to record both Bb & A clarinents. But Eb and bass clarinets - absolutely. Alto should have been included as well and is in the top 3 requests for future update (along with euphonium and solo contrabass).

I can tell now that there's an actually different instrument being used in the upper ranges. Same for bass clarinet - I was a little fast on that one. I though it was one underlying sample set being range limited.

Although checking that ran me into another range issue on the bass - It doesn't go high enough. tbch, those samples aren't the best either - the production around them does wonders, but I'm curious as to whether anyone has checked out the University of Iowa sample set?

I went and found the sfs I'd been using - Laura's clarinet is indeed my playing, and I didn't loop it. Just held the note longer than most samples. UoI is made from UoI set and I did loop those (probably badly). SSO is from sonatina symphonic orchestra. Just checking the ranges, the bass clarinets are extended another octave down(ugh) to cover for contrabass clarinet. I added a half step lower than the Bb could go to the regular clarinets so they could cover As. They all go up... very high. The highest note I played on the Bb was a Bb7. I've heard someone use E7 in performance - they were covering Sarasote's Carmen Fantasy.…

One year later...what is the resolution on this? The topic is marked as "closed" on github. The problem is still there, despite it being a very high priority issue.

There should at least be the ability to take a note and manually scale its pitch. Unfortunately, tuning in playback properties only takes the closest note, so I can't scale a B7 to a C7 because if I set the tuning to 100 cents it only uses C7, which doesn't play back in MuseSounds.

Ranges have been slowly expanding over that year and I assume will continue to do so going forward. There are multiple issues that were filed, and all but one are closed as duplicated to avoid confusion, as per standard practice. The primary issue where this is being tracked is, and it's open (although locked for coming, since the issue itself is well understood and no further comments are necessary to aid understanding). I gather that there is still internal debate over whether or not to simply pitch shift existing samples or to continue the current process of adding new samples gradually.

Thanks for updating me. I was using a flute in MuseSounds as the sound closest to the recorder, but I realized that the highest note for a flute is C7, whereas a recorder can go higher than that. It would be nice if I could manually stretch that C7 to a C#7, even though it's beyond the range of the flute. Is there a place I could suggest additions to musesounds, like adding the SATB recorders?

GitHub is normally the place to report confirmed bugs, as well as to make feature requests after first establishing there is a consensus about how the feature should work. In the case of adding new instruments, no particular consensus would need to be reached first since the design is obvious. But in the case of Muse Sounds specifically, if it's definitely the case the request pertains to it and not to MsueScore itself,. you can use the Muse Hub support site at

I agree. I have found multiple times that the french horns do not reach a high enough range for me. I have also seen Bari Sax reach as low as G.

Also in the next upgrade, Trumpets A4 should follow the same extended Range as Trumpet (in the 2nd Brandenburg Concerto you have a Higher note of G6 so that needs to be added to both instruments), likewise Horns A6 should follow the same extended range as Horn in F, & Trombones A3 should follow the same extended Range as Trombone.
