Using Chromaphone 3 as a Plug-In 75
9 Using Chromaphone 3 as a Plug-In
Chromaphone 3 is available in VST2, VST3, AAX and Audio Units formats and integrates seam-
lessly into the industry’s most popular multi-track recording and sequencing environments as a
virtual instrument plug-in. Chromaphone 3 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 Chromaphone 3.
9.1 Audio and MIDI Configuration
When Chromaphone 3 is used as a plug-in, the audio and MIDI ports, sampling rate, buffer size,
and audio format are determined by the host sequencer.
9.2 Automation
Chromaphone 3 supports automation functions of host sequencers. All parameters visible on the
interface below the Utility section and related to the synthesis engine can be automatized, in other
words parameters from the Home and Editor views.
9.3 Multiple Instances
Multiple instances of Chromaphone 3 can be launched simultaneously in a host sequencer.
9.4 MIDI Program Change
MIDI program changes are supported in Chromaphone 3. When a MIDI program change is re-
ceived by the application, the current sound used by the synthesis engine is changed to that having
the same index, in the currently loaded pack, as that of the MIDI program change message.
In order to use MIDI program changes, make sure the Enable Program Changes option is
selected in the Settings view as explained in section 6.1.
9.5 Saving Projects
When saving a project in a host sequencer, the currently loaded sound 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 packs 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 pack you are using in your
project still exists on your disk when you reload the project. The sounds must also exist and be in
the same order as when the project was saved.
