All t adj said on the subject.
A great diversity in sounds, paterns, etc. ...
cot connectivity is the bare minimum:
Master-out (left, right)
PM
Switch-foot
-Cask
Personally I apprci output increments, but that price is the same when not complain!

UTILIZATION

Trs simple first contact for those who have rubbed shoulders with dj BAR (especially those of the same brand)
For novices, APRS for a while with the manual door by hand, you use it with closed eyes.
I use it mainly in song mode, recording mode step is very Russian and intuitive, like other functions elsewhere (I've only touched)

SOUNDS

Ah! This is the great question: SOUNDS !!!!!!!
that is the problem arises, its banks are, admittedly not gniales.
Cot ism on board (for a machine oriented electronic music that's normal)
We can get some drum kit, table cloths and FX interesting, the rest is a bit lightweight.
For the production of music "a little" Electronic is an interesting tool but it quickly turns around trs same sound.
Personally I use my PC in addition to the few sounds that come out of the RM1X fro therefore moult plug-ins to give good sound.

OVERALL OPINION

I use it for over 6 years to use as I did (see above) I am fully satisfied.
Before I used a RS7000, which is much better, but also much more CHRE!
But couples with a PC (cubase + reason) is a good RAPORT trs-quality price!
For quality sequencer too, is a good machine!
