Low extraction rate

[jianyq]

Hello, I appreciate your work. However, I faced a serious problem when I extracted the melody of Lakh midi datasethttps://colinraffel.com/projects/lmd/, the extraction rate was lower than 10%. The only change we made was to keep only the first element in the loop, the melody track. As a result, we couldn't find the melody track in other 90% midi. Could you help me?

Hello Jian. I'm sorry for the late reply. Can I know what parameter you use when you try the track separation? Thank you.

We just used the default parameter(REQUIRED_TRACKS==melody).
