any way to implement guidance? (humming for example)

What does that mean? What do you want to know?

[betterftr]

to guide music generation with input on top of text like "classical music" + humming.wav or some piano notes stuff like that

It was not designed to be able to input piano notes, and I do not intend to design it that way.
There are other models that are designed that way, so you can use them.
