Frontier Design Group Alphatrack
Mckenzie Witting
The unit is equipped with a single motorised, long-throw, 100mm fader, three rotary encoder knobs with integral push-switches, 22 buttons (with 21 status LEDs) and a horizontal, ribbon-controller-style pad for shuttling the timeline cursor through the song. You can also use two fingers on the strip at the same time, to control the shuttle speed. A 32-character backlit display shows current parameter names and values, and there are direct mode buttons for controlling pan, sends, EQ, plug-ins and automation. The three rotary-encoder knobs are touch sensitive, so the display changes in a context-sensitive way when you adjust one. The knob functions are linked to whichever control mode has been selected using the buttons below. For example, in EQ mode, you can scroll through EQ bands and adjust all the necessary parameters.
A shift button extends the feature set, allowing eight function keys to be accessed and providing alternative functions for the transport controls in some DAWs. Dedicated record, solo and mute buttons reside alongside the fader, which always relates to the currently selected DAW track, bus or output. Note that in some DAWs, such as Logic, the mute and solo buttons control the DAW's mixer-page channels and not the Arrange page mutes and solos, the reason being that Logic can have multiple tracks on the Arrange page relating to the same mixer channel, so you need to be able to solo them individually. A jack socket on the rear panel accepts an optional standard momentary-action footswitch jack for hands-free punch-in recording.
Though Logic 8 has an Alphatrack control surface mode in its menu, this still wasn't working properly at the time of writing (in Logic 8.01), so Logic users will need to download the latest driver and the public beta Logic plug-in from the Frontier Design Group web site (www.frontierdesign.com) to get around this. According to Frontier, Apple shipped Logic 8 with a plug-in that recognised Alphatrack's presence, but that said the plug-in was incomplete. Frontier were then given authorisation by Apple to complete the work that they had begun, hence the public beta version of that plug-in posted for preview. They will post a final version once it has been sufficiently tested and tweaked. However, the only bugs I could find with the public beta version were minor and didn't get in the way of doing the job.
I also discovered an issue that can apparently occur with some laptops and peripherals that are in a system with no ground connection. Initially I found that the display flickered between three control messages whenever I touched one of the three knobs, but unplugging my external hard drive and running the laptop from battery power cured it instantly. It seems that a lot of electrical noise is generated from ungrounded PSU-driven systems, and this can confuse the touch sensors on the knobs. Connecting a piece of grounded equipment to the system also cured the flickering, so it's not a huge issue as long as you're aware of the solution. Sometimes just connecting an Ethernet cable that goes to a network or another computer will cure it as well.
The transport buttons are big enough to be easy to use without taking up too much space, while the fader, with its record, solo and mute buttons, is ideally positioned on the left-hand side. I actually found accessing the sends faster and more logical than with my Logic Control, and although I personally still prefer a physical wheel for shuttling around the song, the ribbon employed here works perfectly adequately. Setting up loop and punch-in points is also very easy, so the only control-surface function I use a lot that isn't available here is the ability to scroll the display zoom value.
The actual operation of the Alphatrack differs according to what DAW you use it with, but I found it very intuitive and friendly with Logic. The display generally tells you all you need to know, and if you're not sure what something does, you can give it a try and see what happens. Often that's quicker than looking for the answer in the on-line support documents. For example, the pan knob's push-switch (in Logic) changes from coarse increments of eight steps to single-step resolution.
