I am using the function looksSlower from the snippet
http://lsr.dsi.unimi.it/LSR/Item?id=305
and when i use it, it produces many warnings such as:
- warning: stem does not fit in beam
- warning: beam was started here
I tested the snippet and it does not produce those warning because it
does not use custom beam
This function is very, very handy to learn music written with complex
rhythm especially in 1/32 and 1/64 notes.
It is going to work with so many custom beams?
The function makes the music look 1 time slower. I was able to make it
look 2 times slower by changing one of the number but I was wondering if
is possible to pass the number as an argument?
