The only product that we publish the interface for is the FaderPort 8 / 16 devices in the user manual is a section that breaks down how the device talks to the application. We don't publish nor make available any sort of API to talk to our products. Perhaps make a new feature request and be more specific, provide as much detail as you are willing to publish so we can more fully understand your request. Or create a support ticket and we can send it along to product management for review.
