Hi Boreg, welcome to Infekted.
Congrats on the purchase.
- The effects, I haven't got a TI to hand so am not totally sure, but I know the effects structure on previous Viruses aren't modular in their design. I figured they went in the same order as they were displayed in the menus.
Distortion > Analogue boost > Phaser > Chorus > Delay/Reverb
The only official 'block diagram' I saw was of the Virus C:

- Unfortunately I think the aux-busses were dropped on the TI, and are instead used for sending the audio over USB instead.
