Virtual Vadim

Name: DJ Vadim Remix Ӣ Rating: Way Cool Ӣ Format: Online Software Ӣ Play

Electronica wiz offers 3D surface wired for sound. Vadim is a Russian-born DJ and a regular on the Ninja Tune record label. His whole site is an audio-game of sorts — every click and mouseover triggers a sample — but click on choice 4 (“Remix”) to access the toy proper. Instructions are made available, and Vadim warns that first attempts are inevitably “messy.” Thanks to Steve Bodow (“I like the idea of environments consumed as pop culture”) for the submission.

Coldcut Software

Name: Coldcut Vjamm Ӣ Rating: Kinda Cool Ӣ Format: Executable Software Ӣ Info

Wackiness from the overworked founders of Ninja Tune Records. Fun, early-stage bonus-track program originally available in a demo version on the album Let Us Replay by the British duo Coldcut. Allows listener to mix various tracks off the album.

Audio Platform

Name: Koan Ӣ Rating: Hella Cool Ӣ Format: Browser Plugin Ӣ Info

Incredibly powerful “interactive audio platform,” not for beginners or otherwise faint of heart. This is a pretty advanced plug-in for your browser (Netscape or Internet Explorer), but more than worth the effort once you get the hang of simpler platforms. Brian Eno, godfather of ambient music, has used Koan to compose what he titled Generative Music 1. Technically, the software is enabled for “online” use, but it’s also a powerful desktop application.

MP3 DJ

Name: PCDJ Ӣ Rating: Cool Ӣ Format: Executable Software Ӣ Info

Spin multiple MP3 files. A great, fun tool for novitiates and pros. Available in a variety of formats, from a fun demo to a rack-mounted setup. Visit the company’s site at PCDJ.com.

Understand that the demo version of PCDJ, much as it resembles the sort of mixer upon which today’s turntablists depend, doesn’t allow for one of the most basic of functions: cue-ing up one track in your headphones while another other plays through the public-address system.

What PCDJ has proven especially good at, though — with mesmerizing results, frankly — is playing two copies of the same MP3 file at the same time. The average techno track, say something by the Orb or BT, creates un-foretold sonic moiré patterns.

This entertainment value also proves true with the work of minimalist classical composers. Rip MP3 files of a movement from a Philip Glass opera and then set one running a split second after an exact copy, and listen to the beading, the way certain tones extend unnaturally and pleasurably. Now, initiate the copy a full meter, or bar, after the first begins, and wait for the work to unfold. It’s quite hard to tell what is echo and what is “original.” (Come summer 2007, it seems strange, in retrospect, to have considered PCDJ, which is today a fairly full-featured program, a game, but that’s what it was once upon a time, and perhaps still is; entry updated July 7, 2007.)
