| Notes | Korg introduced a successor to the i5M: the i40M module. Specifications were similar to the iS40 (obviously, with no keyboard or joystick), but included the Vocal Harmony feature as standard. Furthermore, the module included 3 different pre-programmed MIDI setups, to make connection with various instruments even easier. |
