Scaler setup for Cubase

Hi everyone,
Is there anyone here using Scaler?

Scaler is a Chords analyser/generator,
I would like to trigger it with any other virtual synth, so as Tacman7 suggested (here: https://www.steinberg.net/forums/viewtopic.php?f=146&t=8156&p=739679#p739679) I have created two tracks, one for the synth and the other with Scaler, then I set the input to the synth track to scaler and push the monitor button. Basically it works, I can trigger Scaler with another synth but this way I have no Sustain pedal working ??

Any advices?
Thanks guys
