I don't know if I'm in the good section.. Before you click on the link please read this short text! I have no idea how to make a power append, I know you need to record loudly but also have to be careful because of distortion in the samples. I tried to listen to other powerful utau but I just don't get it... I made a try, I recorded loudly like people suggested but it seems not powerful enough to me. It sounds Strong, a least but not Powerful. Anyway here you can listen to my attempt (please listen the full sample it's only 56 sec).. (sorry for the bad mixing) https://clyp.it/h0s25hrr?token=c72f7cb24a313842b2fc5a88c817eda2 If you have any suggestions, or if you think it sounds okay to be a power append please tell me.
