If I had the choice, I would buy another CMD LC-1 and not CMD DV-1

But it is no more available here in France

The DV1 has also many buttons and knobs that can be used as the LC-1

I have discovered that the DV1 has some shift keys that turn some knobs and buttons to change. So they are kind of multiplied.
You press FX1, and you get 4 knobs and 4 buttons.. You press FX2, and you get another 4 knobs and 4 buttons etc...

It may be good or not...
