Okay ...here are two examples why it could be a "must have"...Any musician that performs with a solo instrument..sax, trumpet, harmonica ...any solo instrument...the CS would be indespensible...

Another...if you are a song writer or arrange songs...I used the CS on the G1000..I had a client that wrote lyrics and I use to record a chord progression to fit the lyrics and the client's melody....After recording to the CS...I would try a variety of styles and combinations to find the perfect fit/feel of the tune...I use to earn $100-$150 for each tune ..with an average time applied....less than a half hour..

Anyone with an open mind can see the benefits in many different ways...

Dang it...I feel a BK-9 coming in handy....
