I have a hard time using rotating knobs as the volume control, especially when doing DJ mixes… It seems I could never get a nice feeling of smooth changes, especially when pushing down one channel and up another one. It might also depend on my current Novation Remote 25 LE that I use temporarily as my controller — while waiting for the perfect DJ MIDI controller to arrive.
I’ve been looking through the current controllers out there. Behringer BRC2000 is a rotary one, the BCF2000 looked OK, but I think the price is too high for what you get, especially as it only has eight rotary controllers — I would like to get three per channel, for a combination of either DJ eq, or with a switch using other effects.
If someone made a MIDI controller similar to the Ecler Nuo4, that would be what I would purchase in a jiffy. Alas, Nuo4 only has volume MIDI controls for two of the four channels.
I suspect that M-Audio will release something similar later, the new X-Session Pro is cheap, has four channels, but somewhat limiting, but it might do the job for the time being until better controllers show up.
I also looked at the Novation Remote SL Zero, my biggest gripe with that one was that the slider ranges were very short, I really want very long slider ranges, with precision… Then again, maybe that’s another compromise I have to live with, as I liked the rest of the design.
