I use it for 1 year. my ex who made the korgd4 me.

It takes a little time to get used to the easy. Since it is compact trs, its functions are superimposed.
I find Gnralement trs well.

But its functions is still quite limited, for example, impossible to record multiple tracks at the same time.
Systmatique must master the tracks one by one for used elsewhere on the computer.

Either we CRER project or lump it well above all its tracks, to which end they masterisent to mp3 or wave.
Be used directly on the mode mp3, faster but more limited on a single file is not audioqui ditable.

Another thing too, we can not do backup project, once the boss suprime even if MTIP is no longer recognized.

Its internal microphone is of good quality but a little too sensitive to the same keys of the device.

The batteries supplied are of good quality but beware, it is disables "the arrangements" prfournit which are useless or that are plutt Gnant.

It comes with a 128 MB SD card, I recommend 1GB plutt, with that you be quiet!
I do not use batteries, others say it's eating too fast.
And finally, dising level, it is beautiful trs.
