Use the TI whichever way you want
If I had one I wouldnt use the TI integration....I wouldnt even use multimode. Im a one sound per synth kind of chappy. Personally id most likely use the TI for pads, wavetables and complex FX. Thats all I'd want or need from it. How about you? What purpose does the TI serve you? Do you use other synths aswell?
