DNJ the motif series will never carry merengue or tangos on it.It is aimed at a completely different market. It has some arranger functions but it is definately not an aranger. The arranger functions are designed to help musicians create in studio and not for live OMB performance alhough it could be adapted in some instances to do this for certain songs. Yamaha understand marketing and would not cannabalise sales from one very successful product range to another.There is more than enough choice available through established arranger keyboard lines, the psr series and tyros series. And i am confident that most OMB players dont even use 60% of the functions on their existing arrangers in terms of sound creation synthesis and sampling. So what the hell are they going to do with a full blown dedicated synth sampler with lots of funk,dance orientated arps????
