The Korg 03R/W is a 32 voice synthesizer that uses Korg's famed AI2 digital synthesis. It holds 229 programs (129 of which are GM in ROM) and 100 combinations which use the 255 preset multisounds (multi-sampled PCM waveforms). The Multi Digital Effects processor provides up to 4 simultaneous effects. The unit has two card slots, PCM Data & PROG Data, is 16 part multi-timbral and has 32 note polyphony. The unit uses a lithium battery (type CR2016) to keep the RAM data from being lost when the power is turned off. There are four audio out and three midi (in, out & thru) jacks.
