Just a quick note for Soundplane players: the new client application version 0.985 is now available in the usual place: the sticky topic in the hardware forums.
The noise performance for all instruments should be much improved over the previous version. To start using the new calibration, go to the Expert page and click "select carriers." Watch the debug window as the client picks out the combination with the lowest noise. This choice will be saved in the preferences file.
I am going to revisit the manual after the 1.0 feature set is complete, so these new features are not described there just yet. Meanwhile, thanks for bearing with me—please post to the hardware forums with your questions and comments.
