Better than the SR16

January 21, 2013

I have had three SR16s, but decided to try the 18 to use on the road. I was so impressed, I bought another to have in my studio. I haven't used the 16 again.

Best sounding

January 15, 2013

Best sounding on the market for the money. I use it in a top 40 band. I would rather have the volume on the spin wheel like my old sr15.

Complicated

August 2, 2012

Absolutely the most complicated piece of electronic gear I've ever bought. Would never have gotten it had I know I needed a Harvard PhD to figure it out. I study the manual every day but still can't make it do what I want. Maybe I'm just stupid (I really don't think so) but I'll probably end up putting it in a closet and getting something I can figure out, without having to go to graduate school. IfI could return it I would do so in a heartbeat. Very disappointed.

Alesis SR18 is a flop

April 17, 2012

Our band planned to use the SR18 as a plug and play during practices when the drummer is not available. We are a wedding band that plays different type of music. We are very disappointed as none of the pre-programmed patterns can be used. They are all so weird! When we tried to create patterns with the pads, it sounded so ruff.

Adds to Live Productions

January 24, 2011

We're having a great time using the SR 18 with its many full sounds. The preset patterns are well programmed and suited to fit in with all music genres. I especially enjoy utilizing some of the Hip Hop, Techno and one particular pattern refered to as "Jungle". All functions are generally easy to learn and handle. I would highly recommend the use of the SR 18 for making your live performances sound full. I utilize the SR 18 in a duo group.
