Some problems of instruments and notations
Why do many exotic instruments sound as same as other classic western ones (e.g. Uilleann pipes and dizi become piccolo or flute, erhu becomes violin) ? Can I turn them into their original sound? How?
Why some notations are useless? For example, the volume won't turn louder after I put "<" on the sheet. Can it be solved? How?
Today I downloaded v3.4.2 and found the pianos sound very different to v2.0.2 (I've been used v2.0.2 for many years). They become much duller than the old version. Can I change it back to the original bright timbre? How?
Please help me solve the problems above. Thank you!
