If the hardware is based on SHARC chips or an FPGA, then in theory software developers could add nearly an infinite number of changes and updates being only limited by the number of chips used and the host computer driving them. There are theoretical limits to each chip but the possibilities far exceed those of custom embedded chips used by most manufacturers such as Yamaha. The Wersi is one such device that utilizes several SHARC processors to produce its audio, sampling, and synthesis. The major advantage of a system like this isn't just the incredible sound quality of the processing card itself, but the ability to swap cards out when a faster card becomes available.
