About the Private MIDI ports.
Spark use these ports to communicate with the controller. We have no way to know if they are opened by the host.
On Mac OSX, the MIDI driver is multi client so the ports will be opened by both the host and the plugin.
The most problematic is the Private In because if it is opened by the host, the host will forward the MIDI messages to the plugin and they will be interpreted as standard MIDI messages, not Spark Private messages. This causes unexpected behavior of the plugin.
On Windows, the MIDI driver is not multi client so if the host already opened these ports, Spark software will not be able to connect to the Controller.
To diable MIDI port on Logic:
- Open the environment window
- Go to the Click&Ports layer
- Then New -> Instrument
call it "Null" or something and make sure it's set to no output port in that object's inspector parameters.
- Cable "Spark Private In" to this "Null" instrument. Now, all MIDI data coming into Logic on that port will be effectively nuked, and will not reach the rest of Logic and interfere with other things.
Of course, you'll need to save this setup as a template or song in order to use it in the future.
About the loudness of the project created with the 1.0. Does it sounds same on Standalone and Audio Unit with 1.1.1?
