Hi, I’m having exactly the same debate in my mind! I went into a shop a little while ago almost sure I was going to buy the VCI 400 but when I saw it in the flesh I was a little disappointed. it was just about a quarter too small! I know compact is a good thing, and it wasn’t really cramped or anything, but I have a vestax mixer and was expecting the filter knobs to be the same size as on my mixer- but they were smaller, and I was expecting the pads to be the same size as the ones on my novation launchpad, but again they were about 3 quarters of the size I wanted. I guess more most people that would be fine, they were easily big enough to put a finger or two on, but I wanted it just a little more spaced out. Perhaps if I actually demoed it with my laptop plugged in I might change my mind, but it made me hold and and wait anyway.
Ive got 19″ rack controller right now and I would like something that looks a bit more like a “proper” 2 decks and a mixer. DJ’ing can be a visual thing so it’s nice for people to be able to see what your doing if possible. So for me, I’m leaning towards the 4track right now, but I’m definitely not going to buy anything until I’ve put my hands on it in person.
