TI Now working in reaper

[boka]

Hello guys! I'm using my TI Polar with Reaper. Could you please help me how could I set it up to just control the synth over the VST ? To be more exact, my RME soundcard is selected as the audio device. If I open up the total control VST, the polar goes to SEQ mode and the sound goes through USB (dunno why as RME is selected). All I want to achieve is that I can record the sound of my Virus (analog out or spdif) thorugh my RME and control the parameters with the VST as well as the with knobs. At the moment, I'm using my AMT-8 as a midi interface but I wouldn't mind using the USB midi of the virus if that would be the only way to my goal....

I'd appreciate any help...

Thanks!
