The Korg N264 and N364 keyboards were 76- and 61-key (respectively) music workstation synthesizers based on the AI2 (Advanced Integrated System) synthesis engine, with eight megabytes of sample ROM first released in 1996. They have 936 programs and combinations, featuring 430 Multisounds and 215 Drum sounds. They have 64-note polyphony. They were the first Korg keyboards to include the Real-time Pattern Play and Record (RPPR) function, which makes it possible to record and save musical phrases as patterns that can then be played back by simply pressing the assigned key. Without sampling features, these keyboards are dated today, though their sequencing function is still useful. Today, the various keyboards in Korg's Triton line are used for similar purposes.
The Korg N364, released in 1998, was a music workstation combining AI2 synthesis with sequencing. This 61-key instrument offered 64-voice polyphony, a 16-track sequencer, and comprehensive effects. The N364 provided Korg workstation capabilities at a mid-range price point.
