Can anyone post up a review of the roland bk7m in live use please . I am unfamiliar with roland arrangers but after listening to the audya live drum and midi drum comparisons I was nicely surprised by the roland. I am a choir musician and do all the arrangements for our choirs so can someone help in the following respects :

1 how easy is it to use live with for example my korg pa1x in terms of changing styles , activating drum fills live on the fly ?
2 how easy is it to customise styles and sounds ?
3 does it have an inboard sequencer ? Cheers
