13 sensor inputs, 4 outputs, the D4 for pure joy! Can serve as a midi interface to control a sampler with 13 triggers! I even triggu drum tracks APRS record falling within the D4 track GC.
Is used in 150 euros (10/2003). There are 21 programs, modifiable will (be back when even!).
There is no effect

Configuration excellent! The edition is super easy, the manual is well done trs trs, a real rgale!
Works with any sensor (rglage gain)
Properly by cleaning a kick drum track I Russi trigguer the GC in the fall within the D4: fabulous!

I agree trs sounds good. Trs good in bass drum, toms, hi-hat, cymbals and a few little snare (weak). The VLOC is excellent. Coupled with a trigger for ddrum acoustic bass drum, a function of Thunder live in the studio.

I use it for one month and I'm in heaven! I love kicks and 13 inputs and 4 outputs, I like less snare (only interesting 3-4).
The report quality price is unbeatable (I cost a ddrum module 4, not bad but expensive trs) 150 euros OCCAZ '
I would do this choice with eyes closed!
