Try to train some new words

[zfishbone01]

hello I am a newer to mellotron, while I want to apply this model to singing songs with sol-fa syllables, and I fond it appear bad when song lyric use sol-fa syllables.
So I try to re-train this model with pretrain, using some no background music singing data, total about 7 minutes, 6 children songs, but finally bad results. So are you have some advice to improve this? Is my data insufficient ? Thank you!
