Chat Musician Node

[Kozatiju]

Hi !

I'm trying to make Chat Musician ( 4_K_M GGUF ) work with different kind of prompts ( even following the one in the given example on the main github page ) and no luck, each time I have this issue : IndexError: list index out of range

---

got prompt

llama_perf_context_print: load time = 8193.59 ms

IndexError: list index out of range

Would anyone have any clue what's wrong here ? It seems to be related to ABC values not being matched properly in the abc_notation but I'm not really sure on how to correct this.

add to end of prompt something like this

Develop a musical piece using the given chord
progression. 'Dm', 'C', 'Dm', 'C', 'Dm', 'C', 'Dm', 'C', 'Dm'

Please respond in valid ABC notation starting with X:1.

It makes it work.
