Elka Rhapsody 490 This was the earlier, smaller version with 49-key keyboard. It had two sounds,
violoncello and
strings which could also be combined to produce a fuller sound. There were two other controls; volume and sustain. It also had a master tuning control on the rear panel of the instrument. It is a monotimbral instrument with a single ¼" jack on the rear for output, and a single 5-pin
DIN socket for a pedal.
Elka Rhapsody 610 This is the larger instrument with a 61-key keyboard. It had four sounds,
violoncello,
strings,
piano and
clavichord which could also be switched in and out, similar to the 490. Each voice had separate volume and decay time sliders mounted on the top of the instrument. The 610 had a split function, which would allow one sound - for example, bass - to be assigned to the lower half of the keyboard, while the upper section could play a different lead voice. == See also ==
