Indicators

There is only one indicator for dynamic errors: velocity of played note. We have to compare it with velocity:

- of corresponding note in the score in order to detect general dynamic errors,

- of previous and next note if the played note should be accentuated.

We have another problem in the case of general dynamic errors: we have to consider that we have only one error even if we have 10 notes which are played too loud (and not 10 errors). The idea is to store the first note $n_{1}$ which is too loud, and then consider we have an error when we get a good velocity again for the note $n_{2}$. Error will be considered as a general error between note $n_{1}$ and note $n_{2} - 1$
