Mixing It Up with the Behringer BCF2000
Using the Behringer as a MIDI control surface is nice, but it does require hand-assigning every button for every project. In my experience, it also doesn't do a good job at honoring the bank selectors—in MIDI mode you have eight tracks' worth of controls, and only that. If you want to mix a 24-track project, you have to be good about grouping your submixes and break your project down into passes. It's a viable way to work, but it can become a pain, and reassigning your faders as you go can confuse you when you change over (naturally, if you're running a number of BCFs in tandem, this limitation ceases to be a serious problem).
There is a better way to use the BCF2000 with Ardour, and that's in Mackie Emulation mode. Basically, you tell Ardour you're already connected to an eight-track Mackie control surface. The Mackie preset gives you a seven-plus-master mix layout, with pan pots at the top (except for the master track—there your pan pot is a jog/shuttle wheel) and each track having mute and solo buttons—very handy. It assigns the tracks in numbered order from left to right (corresponding to your track order in Ardour from top to bottom), with track eight being the Master bus.
Why is this a better way? It gives you access to all the controls on the BCF. MIDI mode allows easy assignment of pots and faders, but try assigning one of the buttons, and you'll find yourself quickly tempted to burn the thing at the stake. Button presses seem to register on assignment, but then when you go to use them, they don't work. This problem may be correctable by building a preset in Behringer's preset building software (Figure 6), depending on the preset you build and your version of Ardour. Your mileage may vary.
Section 10.6 of the manual gives detailed (and accurate) setup instructions for putting the Behringer in Mackie Emulation mode. Unfortunately, the effectiveness of Mackie mode seems to be in flux in Ardour's current development cycle. Some versions work very well—others don't work at all. Again, your mileage may vary (www.ardour.org/files/manual/sn-mackie.html).
Despite the bumps in the road due to Ardour's rapid development cycle, I wouldn't trade this little mixer for the world. It's easily saved me ten hours a week mixing down my podcasts, and the quality of the mixes has gone up as well. Mixing software faders with a mouse is a sucker's game compared to the precision you get mixing hardware faders with your fingers. For $200, this control surface delivers motorized faders and high-definition response in a well-designed, solid package that's fully supported by the Linux kernel and ALSA-MIDI.
That means it's also useful in a number of other high-level MIDI and audio programs for Linux, such as Rosegarden or LMMS or other programs that can accept MIDI control symbols. Let the mixing begin!

In modern computer systems, privacy and security are mandatory. However, connections from the outside over public networks automatically imply risks. One easily available solution to avoid eavesdroppers’ attempts is SSH. But, its wide adoption during the past 21 years has made it a target for attackers, so hardening your system properly is a must.
Additionally, in highly regulated markets, you must comply with specific operational requirements, proving that you conform to standards and even that you have included new mandatory authentication methods, such as two-factor authentication. In this ebook, I discuss SSH and how to configure and manage it to guarantee that your network is safe, your data is secure and that you comply with relevant regulations.Get the Guide
