Dante Inferno...

by Chris Randall
 



A month or so ago, I got turned on to the concept of Dante, which is an audio-over-Ethernet protocol used primarily by big production houses and live sound reinforcement. (I imagine it was invented by someone that had to run a 48-channel snake from the stage to the front-of-house every night, and got sick of being covered in spilled-beer-and-shoe-dirt slime.) In the simplest terms, think of a network, but instead of files and web sites, it serves digital audio. You use normal IT shit like switches and CAT 6 cable, but your goal is shunting massive channel counts of digital audio at ludicrously low latencies instead.

I had known about it for years (you can't help but see the references if you're looking at high-end AD/DA converters, since the usual suspects in that world all have Dante capability). I didn't really think about the ramifications until a friend beat me over the head with the concept. My ultimate goal in my home studio/office is simplicity. The fewer cables I have run, and the fewer conversions I have to deal with, the happier I am. It is especially attractive to me because I run multiple computers of different flavors, and having their I/O talk to each other in more-or-less real time would be excessively handy.

Once I was tipped to the potential, the full OCD Experience kicked in, and I started thinking about replacing my current rat's nest of I/O and monitor controlling. The main attraction to me is ultra-low-latency computer-to-computer connections. I've always thought it is dumb to convert to AES or SPDIF to do a digital computer-to-computer audio interaction, and so do the Dante people. Nominally, a computer-to-computer connection in Dante would be the same as any old-fashioned way, with expensive converter boxes in the way. But Audinate (the company that invented Dante and is the Keeper Of The Holy Scriptures regarding the format) got that sorted in a big way, with three pieces of software that make Dante in a home studio an attractive option.



The first is Dante Controller, which is essentially a virtual patchbay that lets you connect Dante sources and destinations. Dante gear all has a Gigabit Ethernet port, and you basically just run everything to a normal Gigabit Ethernet switch in a star fashion. Dante Controller sees everything on the network, and lets you set clock masters and routings and shit. Controller is free.



The second piece of software is the Dante Virtual Soundcard. This is an ASIO and CoreAudio/WDM driver that works like any other sound card driver; it has 64 ins and outs (which is mildly comical in something like Live. Did you know the I/O panel scrolls? Neither did I) and ludicrously low latency. Any computer running the Virtual Soundcard and connected to the Ethernet rig throws its I/O to the network, and shows up in the Dante Controller patchbay. The driver is US$29 per computer.



The third piece of software is the one that seems like magic to me, and which is useful whether or not you have a Dante system. I only assume it isn't more well-known is because Audinate's business model doesn't lend itself to marketing to hobbyists and home studio folks. It is called Dante Via, and basically lets you route _any_ audio source in your computer to any other. Think of it as Soundflower or Audio Hijack, but on pharmacutical-grade methamphetamines. You can run either this or the Virtual Soundcard. It shows up as an ASIO destination in software that supports that, or a WDM/CoreAudio destination elsewhere. Instead of 64 I/O, you get 8 channels, but otherwise, it is more or less the same, as far as how the DAW works. You just drag-and-drop your sources to your destinations, and you can mix-and-match anything as you see fit and turn any piece of software or I/O in to a sender/receiver. Dante Via is US$49 per computer (which is incredibly cheap considering what you get) or US$59 for a combo of the Virtual Soundcard and Via. There is a 15-day demo of Via on the site.

I purchased a Focusrite RedNet X2P to be my main monitor controller. It comes with a pair of Focusrite's high-end mic pres (their good stuff, not the prosumer Scarlett series). This can be powered off a POE Ethernet switch, so it's just one CAT6 cable to the switch and that's that. It is built like a god damn main battle tank, and is one of those Just Plug It In And Go Because It's Really Well Made For People That Don't Want To Dick Around kind of things. My Adam nearfields go from that, and my desk situation is sorted. I connected the Skull Canyon NUC and my main computer to the switch via their Gigabit Ethernet ports, and with the former running the Virtual Soundcard and the latter running Via (I also use the computer for games, and would like to hear YouTube videos and shit), I have VCV Rack running on the NUC, with multi-channel audio at no noticeable latency running in to Live, with Live Link providing wireless sync over my home wi-fi network. (Note that the X2P comes with a license for the Virtual Sound Card, as well as some Focusrite plugins I'll probably never use, but never say never, right?)

It is early days for Dante in a small studio right now, and many of the I/O solutions that are promised aren't quite here yet. I can easily just plug in a high-end convertor or mic pre rack to the system and it'll just show up. Audinate is releasing a 2-channel class-compliant USB dongle so you can plug in iOS or visiting laptops to the network with ease, and there are several 2-channel AES, SPDIF, and analog solutions to bring legacy gear in to the fold. ProCo and Radial also have similar small-and-cheap solutions either already released or in the works. I've only had this rig working for a day, so I can't really speak to its robustness, but it performed flawlessly with the above VCV-on-another-computer situation, as well as an hour or so with World Of Warcraft and a brief writing session in Live. I gave the mic pres on the X2P a quick check to make sure they worked, but I can't really speak for their all-around applications at this point. I'll put up another post with further thoughts after a month or so with this system.

Skull Canyon...

by Chris Randall
 



Audio Damage will once again have a booth at Superbooth this year, and I'm leaving for Berlin on April 27. That means I have about 3 weeks to finalize everything. The product we're unveiling is in feature-freeze, and it's time to start figuring out how to demonstrate it, as well as the rest of our product line. (This isn't a last-minute thing; I've been thinking about it for some time.)

The entire process is both easier than years past, and more complicated. At the last two Superbooths we attended, we only showed Eurorack, and didn't show our software products at all. This year, it will be the other way around. We have no Eurorack; we're showing our desktop and iOS software. The iOS part is easy; a 12.9" iPad Pro with the usual dongling, job done. For the desktop software, the needs were somewhat odder. The product we'll be unveiling is MPE-capable, so we wanted to have at least one MPE controller at our booth. Since the iOS and desktop versions are identical in that regard, it seemed wise to have one MPE-capable controller for each, and of those, at least one that civilians could play. Roli very generously loaned us a Rise 25 for the booth, so that will attach to the iPad, and my Linnstrument will go as well, for the desktop stuff.

All but a couple of our products are now vector-graphics and HiDpi-capable, so I wanted a 4K monitor to show this off. My own monitor is too big, so I purchased a Dell 23" 4K for the show. Now the trouble starts. You would think it would be a fairly simple matter to sling a computer at this problem and be done with it. You'd be wrong. The software we're unveiling is nearing completion, but it is in no way finished, so it isn't as optimized as we'd like. I don't want to use my main work laptop for a trade show, for obvious reasons, so I pulled out a mid-2013 MacBook Pro, and between pushing a 4K monitor and this fairly heavy-duty plugin, it was screaming for baby Jesus. So, we decided to run Windows instead of OSX for the booth. That being the case, we needed a Windows machine capable of both fairly heavy lifting in the graphics department while shouldering the CPU burden of a DAW. Plus, we have a fairly thin budget and weight considerations. It was a surprisingly tough nut to crack.

After a whole lot of reading of computer gear blogs and fretting, I decided that I had enough time to take a small risk, and I ordered up one of the new Intel Skull Canyon NUCs. As it is a bare-bones system, containing only a CPU/GPU, I also grabbed 16GB of RAM, an NVMe drive, and a key for Windows Home 10 64-bit. All of that showed up this morning.



I'll admit that while I knew intellectually how small the Skull Canyon NUC was, I was unprepared for the reality of it. It is just about the same size as a VHS tape. The power brick is almost as big as the computer itself. Anyhoo, it comes with a pretty good selection of ports (including, improbably, a Thunderbolt 3 port, if you want to run a graphics card in a chassis, or a UAD Apollo or whatever.) It took me about 30 minutes in all to set it up, from opening the boxes to signing in to Windows, after I installed Windows off a USB drive built with Windows Media Creator on my big machine.



We'll be using Bitwig Studio 2 to demonstrate our products at Superbooth (for two reasons: a native understanding of MPE, and a good HiDpi implementation on Windows), so I popped over to the Bitwig site and slammed that on the machine, as well as a few of our plugs and some samples. I've been pressure-testing it for several hours now, and I have to say that, taking its size in to account, this computer is an amazing value. I wouldn't use it as my main workstation, but for situations like this, or for a secondary machine or media center, it is fucking amazeballs. With the caveat that I still have a lot to do before I'll call it Show Ready™, I'm of the opinion that this is a solid machine for the money. Two thumbs tentatively up.

Stand Up, Sit Down, Fight, Fight, Fight! Vol. 2: The Reckoning...

by Chris Randall
 

Lo these many years ago (or maybe six years ago), I went and whittled myself a standing desk solution. All the cool kids were doing it, and it seemed like an excellent idea. I didn't, however, take one thing in to account.

If you read the original article, and pay attention to the fourth paragraph, you'll note that one thing I discovered early on was that I needed to get my monitors in direct line-of-sight. Not long after I moved to that configuration, I added a third monitor, a large Dell 10-touch monitor. (The first mass market cap-touch monitor available, as it happens.) This lived directly under the two original monitors, and you can see it in this configuration in many of my videos and photos of the last few years, as I've used this three-monitor system to good effect.

Anyhow, as it turns out, getting old kind of blows. Not long after I went to this configuration, I needed to get progressive lenses in my glasses. Due to the modular side of the Audio Damage Order Of Battle, I've spent a lot of time with my standing desk and three-monitor rig; when developing plug-ins, I work primarily on my Macbook Pro, and just lounge about the house or on the porch, wherever the mood strikes me. But the embedded dev needs quite a bit of infrastructure, and has to be done at my desk.

Since those monitors are basically six feet off the ground to meet my sight-line, I had to tilt my head back to align the reading portion of my glasses with the text on the screen. I didn't even really know I was doing this, but one day I happened to put the IDE on the lower monitor (normally, Live runs on the lower one so I can touchy-feely plugins, and the IDE runs on the upper left, while the upper right gets folder duties.) When it was down low, all the sudden my neck pain went away. Total accidental discovery, as I didn't know what the cause of the pain was.

So, in general, lessons learned from 6 years with a standing desk: if you can see well, it's a better way to work. It was especially nice during music making, when I'm moving about wiring shit up or whatever. However, if you have progressive lenses, it may be more trouble than it's worth. Take your pick: mild back pain from sitting all day, or mild-to-severe neck pain from leaning your head back to read the screens. I decided to return to back pain for the next while, and eject the standing desk.

tl;dr: my office went to bare walls last week. Today I was able to use it again. Sitting down. And it is much more orange than it was before.

Musical Stylings...

by Chris Randall
 

Although I don't actually make music to pay the rent any more (and thank all the various Gods and wildland færies and whatever for that!) it is still rather important to my personal well-being and understanding of the world to keep my feet wet. I find people that make gear but don't release records to be, well, you know.

To that end, I recorded a full EP, or more of an extended EP, or maybe a short stack LP... eh, fuck it... a pile of songs for Detroit Underground™, which will be released shortly, with remixes from Basek and Proem. I'll talk about that more when it's out.

In the meantime, I have merrily continued to make tracks, like I do. So these two tracks, while being "put out" before the DU™ release, were in fact recorded after it was done. In both cases, everything went through the Euro. If you have any specific questions about a part, I'll be happy to answer to the best of my abilities. But suffice to say both were done with my normal techniques, which I've talked about at length on the AI YouTube channel.

Yo Dawg I Herd U Like Random, So I Randomed Ur Random: Tech Time 008

by Chris Randall
 



To do this video, I went through a bunch of the techniques I use in normal production to add indeterminism to tracks over the course of a couple days. I then sat down to edit it and realized I had over an hour of footage, and I didn't even cover most of the non-Live apps I use, nor hardware.

Randomization is a fucking broad topic.

Anyhow, I managed to knock it down to three techniques. Again, I'll raise this issue that has appeared a few times as I've done these: I'm not entirely sure what's worth filming. A lot of this shit is self-evident to me, so I'm not sure what people find interesting or not.

Anyhow, here you go: some thoughts on Randomization. Necessarily Live-centric.
