A Workaround for Using Atmosphere/Trilogy on an Intel Mac
INTRODUCTION This workaround is recommended for power users with experience
in audio and These guidelines present a basic overview of how your system
can be set-up to use any non-Universal Binary virtual instrument VST/AU plug-ins
in an Intel Mac computer.
You can think of this approach as like having your Atmosphere
and Trilogy instruments in an outboard rack of hardware It works like this: Atmosphere and Trilogy are Power PC-based VST/AU plug-ins that can therefore be loaded into a stand-alone Power PC-based VST/AU host application. On an Intel Mac, the stand-alone host application and the plug-ins would then be running automatically in what Apple calls “Rosetta emulation” mode. While this “Rosetta” approach is not recommended for your primary DAW application, a simple, inexpensive stand-alone host application will work fine running in Rosetta emulation mode, and has the advantage of being able to host any non-Universal Binary virtual instrument plug-ins - including our Atmosphere and Trilogy UVI engine-based instruments. We’ve tested and can recommend Steinberg V-Stack and RAX for use as stand-alone host applications. More info on where to get the correct versions is located here. It is then possible to trigger the plug-ins running in the stand-alone host application from your Universal Binary DAW application via a MIDI IAC bus in CoreMIDI. Additionally, the audio outputs of the stand-alone host can be routed to your audio interface for monitoring or back into your DAW application for printing to audio tracks. This setup will allow the Intel Mac/OSX user to compose
entirely with Atmosphere and Trilogy on a single computer. Here are some of the Pros and Cons to using this particular workaround: Pros
Cons
Remember that these are general guidelines for a short-term
workaround for using Atmosphere and Trilogy on Intel Macs. The application of these guidelines requires
that you are knowledgeable of the audio and Next we are going to show you the principles behind routing
the First, it is necessary to create an IAC bus within Core
MIDI (learn how to set up an IAC Bus). This will allow Once this has been done, you can simply create a MIDI track
within the DAW application and set the NOTE: Be careful in
your routing to avoid Once your This is a good setup for composing or live performance, since there are no significant latency issues to deal with if both applications are set to the same audio buffer size. (For host-specific issues, please see the links at the
bottom of this page). If you have the need to monitor or print the audio output of the plug-ins via your DAW application, you’ll need to physically route the audio from the stand-alone application to the DAW inputs. There are many ways to set up the audio routing to accomplish this, which vary depending on the type of audio interface and the DAW application you’re using. NOTE: Be careful in your routing to avoid audio feedback loops. The following steps show one example of setting up the audio system routing that is effective:
We can recommend one of the two following stand-alone Power PC-based host applications for this workaround (note the version numbers):
- Rax 1.2.3 - AU host downloadable here. (Please read below) As of early 2007, Plasq has discontinued support for Rax and its future is currently up in the air. Users can no longer register the program, and it is therefore no longer a suggested host application for use with Atmosphere and Trilogy on Intel-based Macs. This said, however, you can still download a 30-day trial version of Rax 1.2.3 from the link above that will allow you to try out a single instance of the plug-in at a time. You can use this free trial to determine if using this workaround is workable and worthwhile before investing in a purchase of V-STACK 1.2 from the link below.
