Roland VK-7
The Roland VK-7 is an electronic keyboard which simulates the sound of an electromechanical Hammond organ. Like other electronic musical instruments that emulate (or "clones") the sound of the electromechanical tonewheel-based organs formerly manufactured by Hammond, the VK-7 is referred to as a clonewheel organ.
Since transporting the vintage electromechanical Hammond organs to performances was cumbersome, there was a strong demand amongst musicians for way of recreating the Hammond sound in a more portable, reliable fashion. Refinements to Hammond emulations eventually led to the development of relatively lightweight electronic keyboard instruments such as the Roland VK-7, KORG BX-3 and CX-3, and Kurzweil K2600, that produced a fairly realistic re-creation of the Hammond tone.
Description
The VK-7 is designed to recreates the organ sounds of the 1960s and 1970s jazz and popular music. The instrument has nine harmonic drawbars so that the organist can control the volume of different overtones. The instrument also provides vibrato effects. As well, the instrument contains an orchestral voice section that can be layered with the organ sounds. The keyboard has an 11-pin rotary cabinet connector which allows it to be connected to external rotary speaker, such as a Leslie speaker. It has MIDI inputs, which means that bass pedal keyboards can be used with the instrument. The chassis has a wood finish with alder wood sideboards.
History
Original Hammond
The Hammond organ is an electromechanical organ which was designed and built by Laurens Hammond in 1934. While the Hammond organ was originally sold to churches as a lower-cost alternative to the pipe organ, it came to be used for jazz, blues, and then to a greater extent in rock music (in the 1960s and 1970s) and gospel music.
The original Hammond organ imitated the function of a pipe organ's ranks of pipes in multiple registers by using additive synthesis of waveforms from harmonic series to generate its sounds. The Hammond organ's individual waveforms were made by mechanical tonewheels which rotated beneath electromagnetic pickups. The component waveforms can be mixed in varying ratios by using drawbars mounted above the two keyboards. Hammond organs also have a harmonic percussion effect, in which the 2nd and 3rd harmonic tones can be added to the attack envelope of a note.
Hammond organs have a distinctive percussive key click, which is the attack transient that occurs when all nine key contacts close, causing an audible pop or click. Originally, key click was considered to be a design defect and Hammond worked to eliminate or at least reduce it by using equalization filters. However, some performers liked the percussive effect, and it has become part of the classic sound that modern imitators of the Hammond organ have tried to reproduce. The classic way of amplifying the sound of a Hammond organ is to use a rotating speaker known as a Leslie speaker or cabinet.
First "clones"
Transporting the heavy Hammond organ, bass pedalboard (a B-3 organ, bench and pedalboard weighs 425 pounds/193kg) and Leslie speaker cabinets to performance venues makes it cumbersome for artists to tour with a vintage electromechical organ. As well, the Hammond, as with all vintage electromechanical instruments, faces the risk of technical problems with the tonewheels or electric motor, which may be difficult to resolve in a touring situation. As such, there was a strong demand amongst musicians for way of recreating the Hammond sound in a more portable, reliable fashion.
Some early emulation devices from the 1980s were criticized for their unrealistic imitation of the Hammond sound, particularly in the way the upper harmonics were voiced, and in the simulation of the rotary Leslie speaker effect. Refinements to Hammond emulations eventually led to the development of relatively lightweight electronic keyboard instruments such as the Roland VK-7, KORG BX-3 and CX-3, and Kurzweil K2600, that produced a fairly realistic re-creation of the Hammond tone.
While these instruments were widely used to replace the bulky Hammonds for band tours and club dates, jazz and blues keyboardists still tended to use a vintage Hammond for recordings, because the first clonewheel organs could not reproduce the tonal nuances of the old wooden Hammonds.
