The only disappointment with the TI is the vocoder in my opinion. It would be nice to have the vocoder behave like the commercial virtual ones out there.
By this I mean adding an audio track into say cubase and then route that track into one of the 16 Ti slots together with a chosen midi channel for your carrier.
The only way of doing this at the moment is to physically output a signal from your computer and back in again, very sloppy for a bit of kit that professes to be Totally integrated!
