 "Sound on Sound" Gordon Reid said that the CX-3 "came close to emulating the true depth and passion of a vintage Hammond," particularly when played through a Leslie speaker.The Roland VK-7, introduced in 1997, attempted to emulate the sound of a Hammond using digital signal processing technology.An updated version, the VK-8, which appeared in 2002, also provided emulations of other vintage keyboards and provided a connector for a Leslie.
