I'm not sure whether it's right place to post this here,I just want to
tell that what a great beatcaft drum software it is.
Acoustica Beatcraft may be a extremely powerful program for beginners
of professinals alike.
I found it very accidentally,the I download the trial version,and tried
most of the function,it is quite easy-to-use,and not any limitation to
create drum tracks.
Highly recommend to all of you!
