@dugdum®,
The big argument for the TI is that it can do everything. As with everything, this everything can be much debatable. Its crude arpeggiator and kind of noisy FM + uncooperative wavetable + filter behavior make me miss my MS2000, An1x or Blofeld, yet the most important consequence of this is that I must discard a big part of the synth for which I paid. Comb filter? It's here, but it sounds like shit. Wavetables? They're here, but only some of them sound appealing. ARP-to-Matrix? The idea is cool, but the results are shit due to the aforementioned lack of agility of the sound. So despite the fact that I adore wild synth-mangling and forcing square pegs into round holes and most of the time I'm able to digest such fucked-up sounds smoothly, to my ears trips like that in Virus end up in unlistenable mess.
