Trombone Glissandos and Low Notes

It would be really cool if the MIDI trombone sound could play glisses that are playable on the trombone (or even not playable if it's too much work) smoothly; that is, without going through each chromatic pitch note-by-note. This is one of the ever-decreasing number of things Finale can do that MuseScore can't.

Also, the bottom ranges between "Tenor Trombone," "Trombone," and "Bass Trombone" are just wrong. Tenor trombone (no F attachment) is shown as having a pro range of E2-D5, which is correct. The problem comes in between the instruments labeled "Trombone" and "Bass Trombone." The lowest note of the Musescore "Trombone" is shown as B1, while the lowest note of the "Bass Trombone" is shown as C2. In reality, if we think of the generic "Trombone" as a tenor trombone with an F attachment, its lowest note before pedal tones would be a very sharp C2 and it would not be able to hit B1. This is what makes Bass Trombone different, because by using both valves, it CAN play B1. So, without counting pedal tones, the lowest playable notes should be E2 for "Tenor Trombone," C2 for "Trombone," and B1 for "Bass Trombone." (Don't listen to the websites that tell you that tenor and bass trombone have the same range. If they did, then why would both exist?)

Now to get into pedal tones. Bass Trombone is a unique brass instrument because it is the only one that regularly uses pedal tones as legitimate notes in solo (and occasionally orchestral or big band) repertoire. A high school (amateur) bass trombone player will most likely be able to play at least to Ab1 with good tone, and a professional will be able to play down to Eb1 (and even down to Bb0 but with less clarity/flexibility).

I love this notation software, I hope these changes can be made so it can become even better! Finale will be going out of business in no time!
