Well, I'll try to leave an opinion beyond the RAS ...
The burner is equipped with connectivity Midi in, out ... thru, 2 * 2 output jack, output data backup on K7 audio, headphone output NO ATTENTION!
It contains 49 new sounds (even no effect) ... Apart from the adjustment of tone.
10 bass drum
7 Snare
5 toms
2 open hi-hat
1 closed
3 Cymbals
congas, maracas, agogo, triangle claps, etc ...
There are 16 pads on which to play, its polyphony is 16 tracks (click measurement when recording including mounting).
Ability to record 100 and 100 song patterns from these patterns.
No demo and not recorded rhythm ... at the base, the box is very empty.

UTILIZATION

I quibble a bit early because I had no user manual, but with a good soul of Af, it's done.
Easy to use, there has been a pattern that can be quantified, change the length of the loop ... at the base, was recorded live by tapping the pads (which can be assigned a sound) or by using the Step System.
Then you can make a song (adding up to 100 patterns).
The possibilities morning are quite nice compared to some Br

SOUNDS

The sounds of it ... Bhen 16bits, so all is well.
Only thing is, 49 sounds, it's not enough right now especially since they can not be edited.
No effect, I repeat, but we can adjust the instruments in tune and also the pan.
The expression is good and may even have br "fishing" to conditiond'avoir pads in good condition.
Velocity parameter, but no aftertouch.
I like the way electronic drum toms exagonale 80's damn cheap.

OVERALL OPINION

I use it recently, I had to retype it, it almost waltz in the trash.
Be careful when purchasing to verify that the pad and other buttons work correctly (contact graphite) ... otherwise, will be handyman or switch to noon.
I have other br, notament a Tr-606.
At the risk of being lynched, I prefer it (there's more sound), even if we do not know like live mix on a tr606, we know it sync.
Br A cheap to own if you have nothing else, it helps out well.
