Vestax has a solution

Vestax was thinking about a compact DJ solution: the result is here, called VCM-100. It can be used as on the picture, and functions as an audio interface and a MIDI controller in one. It has four analog inputs (with 18 bit resolution), and four analog outs (20 bit), and you can adjust a total of 60 different MIDI controller in the same time with its tricky switches. It runs on USB power, and made of metal fully. Price is still a secret, check the product page to learn more.

A new DJ sampler from Roland

Roland's biggest news at NAMM is this DJ sampler called SP-555. It samples everything: analog line and mic signals, plus the digital USB audio stream also. It imports of course the most important file formats: .wav and .aif. It has the superb infrared controller called D Beam, and a huge selection of DSP effects. It is expandable with standard CompactFlash cards up to 2 gigs of sampling memory - and you can synchronize your samples to any video performance with Roland's proprietary V-LINK technology. And a real surprise: the gadget functions as a computer audio interface also, via its USB socket (Sonar LE software package included). A/D and D/A conversion is performed in 24 bits.
