The Pa1000 represents Korg's professional arranger tier, with over 1,750 sounds, 430+ styles, and four times the PCM memory of the Pa900. The 61 semi-weighted keys support velocity and aftertouch, and the two 33-watt amplifiers driving four speakers produce genuinely full, room-filling sound.

The 7-inch color touchscreen doubles as a KAOSS-style effects controller for creative real-time manipulation. A TC-Helicon vocal processor handles up to three harmony voices, and a built-in Style Converter turns MIDI files into custom styles. With 128-voice polyphony and deep editing capabilities, this is a serious professional instrument for working entertainers and solo performers.
