Those thinking about replacing Process cards (rather than simply installing additional Accel cards) might actually see a drop in DSP resources until their plug-ins are fully updated. So the thing to be aware of is that a plug-in that has been updated for Accel may actually just be compatible with the two older chips. In fact, all Digi's own plug-ins - and those co-developed by them - are already at this stage.ĭigidesign's Impact mix-buss compressor is the first plug-in to take advantage of Accel's faster DSP chips.What's confused people is that most independent developers will probably do a two-stage update: a quick one that supports the older chips, and then a complete optimised reworking to support all chips. Ideally, existing plug-ins will be updated so that they work on the new chips (and are optimised for extra instances) as well as the old ones. ![]() Due to an unexpected technical 'banana skin' it turned out that existing HD plug-ins didn't work on these two 'compatibility' chips! A simple fix is required for plug-ins to work (the code just has to be recompiled based on the new Digi Software Developers' Kit). Here's where a whole bunch of confusion has arisen. These two older chips are intended to share the work of audio recording and playback, and also provide compatibility with plug-ins that have not been updated to run on the new chips. Alongside the seven faster chips, the cards have a further two processors identical to those found on the original HD cards. Four of the new chips have access to a generous amount of on-card RAM. Accel cards sport seven audio processors that run at a little more than twice the speed of the DSPs on HD Core and Process cards. Pick & Mixįirst the technical bit (bear with me, because this should make what follows clearer). Otherwise it's possible to run additional software via the computer's built-in audio system, or even another (non-Digi) interface. These days this is not so much of a problem, as you can probably route peripheral software into your main audio application via Rewire, or run virtual instruments as plug-ins. Both the ASIO and Core Audio drivers are single-client, meaning only one program at a time has access to your Digi box's I/O. The Mac drivers come with a setup application for selecting which of your audio programs will use the driver. The purpose of these is to enable non-Digi audio packages like Logic and Cubase SX to work with Digidesign audio interfaces including the 002 and 002R. Alternatively, these drivers are now available via stand-alone installers. The Pro Tools LE 6.1.1 update includes new OS X Core Audio and Windows ASIO drivers. Let's look a little deeper at the new technology, and the practical matters such as plug-ins, compatibility, and whether to exchange Process cards.ĪSIO/Core Audio Drivers & Pro Tools LE 6.1.1 ![]() So that's the basics, but existing HD owners seem a little confused and uncertain about what to make of Accel. As usual there's an extra concession if you bought into HD recently (since July 20th). If you've already got an HD system but have no spare slots (or you just want the maximum possible DSP) there's a reduced-cost exchange program for swapping out original Process boards. In addition to the extra plug-in power, HD rigs with these new cards will benefit from 50 percent higher voice counts, meaning a new maximum of 192 audio tracks at 44.1 or 48 kHz. However, on new systems, additional cards will now be Accels instead of the original HD Process cards. The 'master' HD Core card is unchanged, so the basic single-card HD system is the same as it was before. Rather than a being completely new system, the HD Accel PCI cards are designed to slot into Digidesign's top-of-the-range Pro Tools HD system. With the DSP power doubling 18 months since the appearance of the previous card, I'm supposed to mention Moore's Law at this point - but I won't. We investigate, and try to clear up some of the confusion surrounding the release.Īs you'll probably have seen in SOS's News pages, Digidesign have released their latest DSP card, with the traditional promise of doubled mixing/plug-in capacity per card. HD Accel is the latest processor card for Pro Tools HD TDM systems.
