Given that Im not super versed in midi and only just got my ND:
I can set a global ch on ND, then assign each pad with one of the note numbers 0-7 which corelates to ch 1-8 on DT. So yes you can trigger individual samples on DT using ND this way. The other option would to set each pad to its own midi channel, which I’ve not been able to do, but that could be me missing something.
Side note:
If you are a drummer and have the possibility, I recommend to test as many different pads as possible before buying. My take is that different pads have really different velocity response and feel, besides their features.
Personally I like the ND 3p very much, but if you are planning to use the pad as drum replacement you migth find that the 6 pads and no hihat ctrl is to limiting.
