It's nice job about singing synthesizer. There are some questions about ScoreDraft:
(1) which pitch shifting method using in ScoreDraft?
(2) which time shifting method using in ScoreDraft?
(3) It seems there are some noise in singing voice synthesizer case, so how to reduce noise or solve it?
(4) from the source code, ScoreDraft is concatenated based method, do ScoreDraft have plan use HMM or DNN based method?
(5) What about the future plan of next version?
