The Sends implementation of the FaderPort 8 has changed as of firmware version 1.1.
See below for the new changes in workflow.
Initial press of "Sends" will get you into the Sends "Mix" mode.
Parameters for the first Sends bus, will map across the FaderPort 8 with one parameter shown per channel.
"Prev" and "Next" buttons will page through the "Sends" parameters which are controlled via the faders.
The Big knob encoder will page through "Sends" slots 1 - 8
Second press of "Sends" will get you into the Sends "Channel" mode.
The FaderPort 8 focuses on the 4 parameters of the first 2 sends. That is "Send 1" Bus, Level, Pre/Post, and On/Off and the same for "Send 2".
Access the additional sends using the "Prev" and "Next" buttons to page to Sends 3 - 4, then Sends 5 - 6, and Sends 7 - 8.
