Hit the Effects button, then keep scrolling the pages left until you see "1 INPUT", followed by "Mode = Off" below it.
Change the value of Mode from "Off" to "ToEffects" using the value buttons, and you can then use the effects as you would normally.
Alternatively use "Static" if you also want to run the Vermona through the Virus's filters and saturation and other modulations (LFOs etc.), or "Dynamic" if you want to further gate the input by hitting a key (allows you to bring in EGs and the like).
If you need to boost the inputs, or select which input channels you want to use, you can also access these by paging to the extreme left on the Effects menu pages.
PS > And another thing! Will the Ti|3 have user customisable/importable wavetables?
A ribbon-controller or XY-Pad might be nice, too, please! Thanks!
