Greetings, FSX!
If you stick to using MIDI, and only MIDI with the Virus TI, you'll not be using the TI, only the Virus! (^_^)
No, seriously, the TI functionality is delivered from the USB connection. So, not only are you sending the MIDI over USB, but you're also sending your Audio direct into, and out of, the DAW! Or, maybe you've got another synth routing its audio into the DAW via the Virus... ETC!
