I want to experiment with some outboard effects but not sure how to route and make this happen
First, you need to know if your outboard gear can be analog or digital ? Is there AES3 on your gear, with the capability of 96kHz or 48kHz ?
There's an option in patch page to change the AES sample rate (the wrench).
Then you have to connect it to the console (output and input - AES3 or Analog) and you have to patch it in the patch page of your console. Generaly you might want to use an AuxSend for effect like delay or Reverb, or you can use insert for dynamic effect.
Hope it helps.
