Awesome!

As great as the ND2 is, I think the ND1 is a better fit for A4.
You’re not paying for a lot of features you wont’t use (midi CC control, 5th and 6th voices, though you could layer those tracks but it requires tricky CV splitter cables.).
The added synthesis of ND2 is great, but I think thanks to the external input being p-lockable on the FX track, some pan and fx send p-locks breathe new life into the ND1. And since it is mono, you can run it through the cheapest of bass guitar pedals on its way into the A4.

I just wish the midi program changes were more instant from A4. It seems to follow the master pattern length in the scale setup. Kind of a bummer for direct jump if you switch the ND1 kit programs up a lot.

Anyway… Party on, Wayne!
