Is the virus A the same engine as B and C

[Coxy]

I heard that B and C of the access virus where a new sound engine from the Virus A, as in it can sound different?

Is this true or not?

Series comparisons
The Virus has had 3 major hardware revisions since the original Virus A model as well as having numerous features (both minor and major) added via firmware operating system updates. The Virus engine has largely remained the same since the Virus A up until the Virus C. They all utilize a single Motorola DSP chip and the sound is identical between models when not factoring in the additional features provided by each hardware and firmware upgrade.

The latest incarnation of the Virus, The TI, utilizes 2 DSP chips and represents the most significant technical overhaul of the Virus series since its inception.
