FX Send

Unable to apply Apogee FX Send mixer as Inputs to Cubase Group channels

When you created a Group channel in Cubase, then any FX Channels that exist will get automatically added as sends. The program does this to prevent feedback loops.

To fix, you have undo this by removing the new Send (select “No Bus”) from the Group channel.

What are the analog and digital in/out numbers in my recording software for Element & Ensemble Thunderbolt?

Apogee interfaces provide a driver-supplied label for each input and output channel (see this video for an example in Logic: https://apogeedigital.com/blog/apogee-element-tutorial-enable-logics-io-labels)

If your DAW (recording software) does not read this and only shows the channel number, use this guide to match the channel numbers with your Element or Ensemble interface:

Element 24

Element 46

Element 88

Ensemble Thunderbolt (Inputs)

Ensemble Thunderbolt (Outputs)
