拍子問題...

actaully if you have learnt music theory, your beat sense will be better. But in your case, the only way is tht you practise more, at first use da beat machine to help you during playing, later when you adapt to the way, play without the mahcine but count in your heart, later on, you try not to count da beat, time will do!!! Hope i can help you.

Yup, I agree.
You should try to develop a sense of rhythm rather than counting all the times.
You can achieve it by counting every beat in your daily practice, just as scales or some others, (I don't which one you are using, but there must be some).
Try to memorize those rhythm like dotted, Scottish snap and syncopated notes, from time to time, you will find out that most rhythm are just lengthened or shortened basic rhythm.
The day will come, practice make perfect.
P.S. Rhythm is definitely important, especially in an ensemble, and sometimes your feeling may fool you, so don't rely on it, unless it is your experience and not just feeling.
