Sometimes, simple stuff matters. DJ mixers like Pioneer’s DJM-800 have simple, single-knob low- and high-pass filters. Laptop software often doesn’t. Enter FZero, with his free and open source Single Knob Filter to fill the gaps. (Windows-only, built in SynthEdit, but it’s open source and schematics of the basic signal processing are available, if anyone wants to translate this to Mac.) Drop this into an insert in a tool like Ableton Live and go play.

It’s apparently a big improvement on an Ableton forum solution that used 127 different filter instances in a rack.

I’m aware of the goodness of Single Knob Filter thanks to the Aurora open source DJ mixer project (see yesterday’s write-up); they assign an instance of the plug-in on each of the Aurora’s two mixer channels. Aurora’s Matt originally had the SKF plug-in in their Ableton template, but I encouraged them to replace it with Ableton’s Auto Filter for cross-platform compatibility and ease. That said, for plain DJ filtering, this it the One True Knob.

Now, go forth and use it on some crazy experimental noise soundscape you’ve been working on, just to spite cliche.

Adam Dworak aka DJ Destruction writes to let us know he’s finished a video review of the ZERO8:

Via the DJ Destruction blog.

About halfway through, he gets to some hands-on demos with the internal effects and controllers, which demonstrates some of what makes the ZERO8 unique. Thanks for sharing this one, Adam!

Adam’s rig — the mixer, a DJ app (Virtual DJ), and use of the internal mixer and effects — qualify him as what is likely the target audience for the ZERO8. And you can see he’s pretty happy using it in that way.

We have heard some dissent, though, from people who wanted to use the ZERO8 for live laptop performance with Ableton Live, or with DJ sets that push the envelope a bit into the live performance area. In fairness, that may not have been the ZERO’s target audience, but as it is a target audience for CDM, I’ll be interested to see what gear can fit the bill.

Also, I don’t like to bring up anecdotal evidence, but do any ZERO owners out there know if Korg was able to resolve the “hiss problem” we heard readers complaining about?

What about the alternatives?

For various reasons I remain interested in the Ecler line. I don’t think it’s immediately comparable to the ZERO, but its focus on combining MIDI control and mixing features make it very interesting to the Ableton crowd. That’s nothing against the Korg kit, but in this emerging category, it may be closer to what this niche wants. I hope to look more at that soon. See our previous story (which also includes commentary on the Korg, so I’m not the only one making the comparison):

MIDI + Mixing: Ecler EVO4 DJ Mixer Specs, EVO5 Update

There’s been quite some interest — and discussion of the relative merits of high-end mixers — in the boutique DJ mixer Ecler EVO4. It’s a more svelte rendition of the EVO5, and also doubles as a hybrid MIDI control surface. There’s still no word on pricing, but if it comes anywhere close to a US$1000 street, I think it could be serious competition for the cheaper but apparently flakier Korg ZERO range.

At least now we know what the thing looks like:

I like the design — it’s not hard to imagine digital musicians and laptopists/electronicistas having good fun with this as much as traditional DJs. The MIDI controls look a little disappointing, though.

Previously (with lots of comments):

So, you’ve got a mixer, which is a box covered in faders and knobs that processes audio signal. And you’ve got a MIDI control surface, which is often a box covered in faders and knobs that looks a mixer, but doesn’t process audio signal. Why not combine them into one device?

That’s the approach taken by DJ-focused mixer maker Ecler. Their EVO5 (shown at right) does all of this, but at a hefty price premium — about U$1900 street. (That price could be more worth it, however, with updated firmware capabilities — more on that in a moment.) A rumored EVO4 at a lower price (expected at a non-cheap, but possibly mortal-compatible US$1000-1500) has been making the rounds on the Web. Today, Ecler confirmed those details and promised the final unveiling at Musikmesse next month in Germany and here Stateside for Remix Hotel Miami later in March.

No photo or official pricing yet (meaning if you’ve seen a photo, it’s an unauthorized leak or fake), but here’s what Ecler has to say:

The convergence of visuals and sound on virtual vinyl has been a long time coming, but it’s awaited the perfect tool for controlling both. Serato’s VIDEO-SL promised to be that tool. We’ve gotten the crossfader in the capable hands of dj rndm and Robotkid to find out for Create Digital Motion. Here’s what the results look like, mixing:

… and scratching:

The review isn’t without the odd caveat: for one, you’ll need to pluck down a couple grand to get the complete setup because the Rane mixer employed is required, though rndm ultimately says that’s worth it for the integration payoff. And available transitions and effects are limited in range and prefer to run on dedicated GPUs (think MacBook Pro, or a PC laptop with a dedicated NVIDIA or ATI card). But as you can see, the results are incredibly slick, and there’s no question video on vinyl now has a tool to beat. Check out the complete review and technical details on our visualist sister site:
