How has the ND2 + A4 combo been for you?

As much as I love the A4, I’m looking for a trigger based drum solution to free up the 2 A4 tracks I use for drums. I’m considering the ND2 for my A4.

I prefer to make entire tunes with one Elektron sequencer at a time. ND2 seems like it is the best A4 add-on for this purpose.
