The Bass Clarinet needs a bit of work. The range needs to include the extended range (concert C, B, and Bb). The range also needs to be slightly higher (up to a very high concert C#).
Also, the playback for the low notes is delayed the further you are going down. It is frustrating when I have 16th, even 8th notes that are inaudible and are important to be heard. It also sounds weird when there is a long low note that comes in a fraction late to where it should be. Obviously, as you go into the very low clarinets, (Contra-alto, Contrabass) it gets even worse. Can it please be fixed because it is frustrating me and I am missing a lot of important Contrabass, Contra-alto, Bass, and even Alto Clarinet parts that should be heard.
P.S. Please no later than the release of Musescore 3 :)
