Worth Every Penny!

Bought mine from Sweetwater April 2013. I have a one man band show using midi backup files I write using Cakewalk from my laptop. Use the unit as a sound module weekly now for over 3 years. Plays my midi files flawlessly and is still running like it just came out of the box. People at the gigs are still amazed at the sound. Andy was my rep; arrived from SWtr quick/ready to use.

Nice unit that does what it claims to do!

I am giving the BK-7m a 5.0 rating simply because IMHO it does everything it claims to do and does it well. I have been a user of Roland equipment since the early 80's and the BK-7m has made me another satisfied Roland customer. I have only had it a couple of weeks and look forward to becoming a proficient user. I have already purchased some 3rd party "Styles" on a USB flash drive and am greatly satisfied. However, research such a purchase as I understand there are some sellers of these Styles that do not have satisfied customers. Anyway, as a keyboard player for 35 years, I am 100% with the BK-7m and the current Sweetwater price ($1000) is great. This is my first "arranger" of any kind. Very cool for song writing inspiration.

Still learning....so much to offer!

The BK-7m is truly amazing....a band in a box. The possibilties are huge not only to adapt existing songs but to create from the preset with a huge variety of genres.

Great Addition To Keyboard

This is the perfect backing track sound module to compliment a keyboard or any other midi instrument. There are 1000+ tones, over 50 very playable drumsets and covers all popular types of music. Lots of tweakable parameters & user friendly menu Was able to set it up in minutes. Excellent transaction with SW. Shipped quickly! Customer Service always a pleasure to deal with and provided answers to all questions I had concerning this unit. Highly recommend this item!

Nice Unit

Very nice compact unit. I am not sure why the arranger kicks in on start-up sometimes even though I supposedly programmed that not to happen. I bought this so as not to have to carry a Yamaha Tyros around all the time. For my use it has filled this purpose very well. As others have said, a more detailed manual would be helpful at times, that's why 4.5 stars.
