I'm with an old trumpet that sold me in Si Bemol(Bb), I'm still learning, and my biggest difficulty in music is being able to be constant in the sounds that come out of me, to reproduce them when I want and not randomly, that is, my ear does not make a difference very well the notes, and with that I can not reproduce, so I decided to train my problem using an online tuner:

The problem is that I do not know if training with him is according to my trumpet, and I may be training wrong, which would be bad. If not is  according, can recommend me one so that I can train to hear the sounds coming out of me.
