MIDI real time automatic problem.

Hello.

I need help in the use of the real time feature.

When I'm going to record listening the metronome and setting a crotchet as default time, I can record with no problems the notes with a crotchet duration or longer duration like a minim... the problem is that if I record notes of a smaller duration like a quaver or semiquaver, the program does not recognized them.

What I have to do to can record notes of smaller duration?

Thanks to all.
