 By the 1990s and 2000s digital signal processing and sampling technologies allowed for better imitation of the original Hammond sound, and a variety of electronic organs, emulator devices, and synthesizers provided an accurate reproduction of the Hammond tone, such as the Kurzweil K2600 and Clavia Nord Electro keyboard.Hammond Suzuki USA currently markets numerous home, church, and professional models that digitally reproduce the sound of vintage Hammond tonewheel organs.Some sophisticated emulation devices have algorithms that recreate many of the nuances of vintage Hammonds, such as the "crosstalk" or "leakage" between tonewheels, the sound of dirty key contacts, key click, a growling tube amplifier, and digital simulations of the rotating Leslie speaker cabinet.
