60 Using Ultra Analog VA as a Plug-In
7 Using Ultra Analog VA as a Plug-In
Ultra Analog VA is available in VST, RTAS, AAX and AudioUnit formats and integrates seamlessly
into the industry most popular multi-track recording and sequencing environments as a virtual
instrument plug-in. Ultra Analog VA works as any other plug-in in these environments so we
recommend that you refer to your sequencer documentation in case you have problems running it
as a plug-in. We review here some general points to keep in mind when using a plug-in version of
Ultra Analog VA.
7.1 Audio and MIDI Configuration
When Ultra Analog VA is used as a plug-in, the audio and MIDI ports, sampling rate, buffer size,
and audio format are determined by the host sequencer.
7.2 Automation
Ultra Analog VA supports automation functions of host sequencers. All parameters visible on the
interface can be automatized except for the Polyphony, Bank, Program and History commands.
7.3 Multiple Instances
Multiple instances of Ultra Analog VA can be launched simultaneously in a host sequencer.
7.4 Saving Projects
When saving a project in a host sequencer, the currently loaded program is saved with the project
in order to make sure that the instrument will be in the same state as when you saved the project
when you re-open it. Note that banks of programs are not saved with the project which implies that
if you are using MIDI program changes in your project, you must make sure that the bank you are
using in your project still exists on your disk when you reload the project. The programs must also
exist and be in the same order as when the project was saved.
7.5 Performance
Using a plug-in in a host sequencer requires CPU processing for both applications. The load on the
CPU is even higher when multiple instances of a plug-in or numerous different plug-ins are used.
To decrease CPU usage, remember that you can use the freeze or bounce to track functions of the
host sequencer in order to render to audio the part played by a plug-in instead of recalculating it
every time it is played.
