NDSP plugins using external effects in the routing?

[Zak]

I need HELP with setting up my new ISP Hum Extractor + Decimator G guitar pedal with NDSP plugins.
This ISP magic box is supposed to be the best guitar hum annihilator atm.

The HUM EXTRACTOR + DECIMATOR G is two effects in one box, a HUM remover and a Noisegate.
The Hum Extractor part removes the 50 and 60 hertz AC hum frequencies along with their harmonics reducing the requirement of the DECIMATOR single ended noise reduction to only have to work on gain noise and hiss.

The DECIMATOR noisegate part is controlled from the direct instrument input allowing the noise reduction to work equally when switching between high gain and clean settings.

I need to use the ISP entirely in a sim VST software DAW environment.
I am attempting the ISP Hum Extractor + Decimator G routing with the following hardware and software:

1. ISP Hum Extractor + Decimator
   
   
   
   
   

In this taken from the manual example configuration the HUM is eliminated in the signal between the guitar and the input of the pedal chain and the DECIMATOR is in the signal path after the preamplifier of the guitar amplifier.

This allows the DECIMATOR to remove all noise introduced at any point in the signal path and will not require any threshold change when switching from high gain to clean tones.

NOTE: when using longer time based effects like echo, delay and reverb it is best to insert these effects after the output of channel 2 to avoid cutting off reverb tails or echo spillover.

For that reason I am using two NDSP sim plugin split in half (twice).
In the first instance I am using only the effects and the amp part of the plugin and in the second instance I am using only the time based effects of the plugin.

2. Radial J48 DI Box (Input / Output / Thru)
   

   

3. Radial EXTC SA Reamp Box (Input / Output / EFX Loop A / EFX Loop B / 2 x Send / 2 X Receive)
   

   
   
   
   

4. Focusrite Clarett+8Pre USB Interface (10 Inputs / 12 Outputs)
   

   

5. Logic Pro or Reaper

6. NDSP plugins

I have tried using the dedicated in my DAWs (Logic Pro or Reaper) I/O and ReaInsert utilities that serve as digital patch bay allowing us to integrate external audio effects similar to using internal VST sim effects.

I have failed to understand sufficiently the information in the manuals and route properly in order to make it work. I am lost, so if you can, please HELP with “Routing for DUMMIES” style explanation.

Problem solved thanks to the Thomann Customer Support.
I’ve reached out to Radial, Focusrite and ISP, but Thomann were the only one to write back with instant GERMAN solution to my problem.
