Steinberg had a bevy of announcements regarding its Nuendo production system in New York last weekend. Nuendo 2.1 will be available this month at dealers worldwide, featuring new collaboration tools for multiple users to work via TCP/IP. ID (for Input Device) is a new control surface for Nuendo that's intended to feature a traditional "console" design. Lastly, Nuendo will now support the DTS encoder for digitally encoded surround sound in that format.

Nuendo's networking capabilities support (amazingly) the full range of editing tools from audio to MIDI to video. There's also data management over a server from Nuendo 2.0; under 2.1 you can combine separate projects via the network.

Traktor DJ Studio 2.5 features a redesigned time stretching engine allowing pitch-independent tempo changes of up to +/- 30%, or tempo-independent pitch shifting of up to six semitones, without audible artifacts.

EUR/US$199, EUR/US$49 upgrade (download) or EUR/US$69 (boxed). Available immediately.

Radial is a fascinating Mac-only loop-based composition and performance tool, but its release earlier this year was largely overlooked since it lacked OS X support. That should change soon: Cycling `74 has announced Radial 1.1 with full Mac OS X support plus new file grouping and improved sync capabilities. Radial is "not simply another loop sequencer" says Cycling `74, but a performance tool uniquely optimized for live performance. Extras include a dozen Pluggo effects, a free library of loops, and now new plug-ins for live audio input, parameter automation, and reverb. Stay tuned for a review soon to see how Radial stacks up to Ableton Live for live performance. US$199 MSRP, expected to be available early November.
