Good songs, Blade! They have a nice polish to them. I also like your selection of synths.
Did you upgrade from a Virus C to a TI? I heard that you can import Virus C sounds to a TI, so you can sell your old Virus C without losing your patches. I'm thinking about doing just that but I'm not sure if the TI has enough unique sounds to warrant spending the net extra $1,000 or so. What do you think?
Actually, I sold my C desktop module to help finance some other gear. I missed the Virus sound so much that I bought the TI (keyboard version), a year later. As far as going for the newer model, it depends on whether you need it for the differences. Some people have said that the output of the C is more "balsy" than a TI, so if your ear is really tuned to it, you might notice a difference.
I know there is a difference in programming, because many TI sounds are swathed in reverb. On the C model, you have to choose between either a single Reverb or Delay. You can't have both. The TI allows 16 Reverbs and 16 Delays (in a Multi) simultaneously.
There are quite a few synth/effect differences, which is important to a tweaker like myself. Hypersaw is very cool, as is the ability to sweep through wavetables. The oscillator also offers Formant and Granular modes. Some of the new effects include the Atomizer (stutter audio), Comb filter, etc. I love it, but I think the C remains highly useable. I would suggest trying someone's TI before buying it.
As stated, the TI can play all C patches, but the effects may make a program sound different.
