The RADIAS integrates a synthesizer, effecter and vocoder into a single unit. The synthesizer has 24 voices, a variety of synthesis algorithms with multiple effects, a new comb filter and wave-shaping features, as well as new formant-motion vocoding. The 16-band vocoder was among the capabilities enabled by Texas Instruments' TMS320VC5502 16-bit, fixed-point Digital Signal Processor (DSP). Korg engineers considered the 300 MHz (600 MIPS) VC5502 DSP with a core optimized for sound processing as the best choice, since it could easily implement the complex functions required in the RADIAS and it had low power consumption.
