The Virus TI hardware doesn't have a breath control input jack, if that's what you mean.
'Breath' is listed in the mod matrix as a source. I'm not familiar with the Akai unit, but it looks like it has midi out.
If it send BC (CC#2):

then you just have to select 'breath' as the source, and assign what you want to modulate.
If it sends something else (unlikely), then you may have to re-assign controller #'s within your DAW program, if it supports that function.
