      Hey all,
      I’ve been testing different routing solutions.

      I think I have worked out my ideal Audio signal chain.

      Originally I had the H90 in the Loop of the GT1K and then realised use the H90 in 4CM with the GT1K.

      GAT -> H90 IN 1 -> H90 OUT 1 -> GT1K IN -> GT1K SEND L+R -> H90 IN 3+4 -> H90 OUT 3+4 -> GT1K RET L+R -> GT1K OUT L+R -> AMPS/DI/INTERFACE

      But what I don’t understand with the H90 is the difference between Insert mode and Dual Mode.

      Insert mode can be thought of as 1 main audio path for the H90 (I/O 1-2) , with 2 mono or 1 stereo insert points. These insert points can be placed anywhere in the main path.

      Dual Mode instead has 2 paths (Path 1 = I/O 1-2, Path 2 = I/O 3-4). There are no insert points in Dual Mode.

      It sounds like you want to be using Dual Mode for your setup. Let me know if that clears things up.

      Thank you for the reply 🙂

      Sorry if I’m asking a more straightforward question

      So my signal chain looks like this:

      GAT -> H90 with GT1K in the Loop

      The term “Insert” gives me the impression that there is the capability of inserting an effect (Send and return) into the signal chain

      I thought that was the same as 4CM? where the preamp is “inserted” into the H90 signal path?

      Thank you so much again for your support! I love Eventide!

      You’re welcome.

      You are correct about your impression of the term “insert”. That can be anything from a preamp, distortion, delay pedal etc.

      What I refer to as 4CM can also be thought of as Pre/Post, where an amplifier has an FX loop. The “Pre” path goes directly to the input of the amp, the “Post” path is the amp’s FX loop. This is shown here: https://cdn.eventideaudio.com/manuals/h90/1.5.2/content/setup/pre-post.html

      Dual Mode with 4CM or Pre/Post may be desirable with your setup if you wanted the H90’s effects on a separate path from the GT1000. You could have the GT1000 + H90 effects on Path 1 with nothing on path 2, or GT1000 on Path 1 and H90 on Path 2. You would need some way to mix the signals together.

      You could also process 2 instruments at once, for example, guitar on Path 1 and synth on path 2.

      You should use whatever works for your setup. The GT1000 on the insert path of the H90 sounds like a good option.
