The ELKA PANTHER ORGAN (Elka Panthera pardus organum) has now been tamed and put on a leash as a VST/AU plug-in for both Windows and Mac platforms. This big cat can now be delivered to you by Generalmusic by Soundion, tamed ready for the cage that is your computer by Martinic.

ELKA Panther was one of the most famous organs in 60s’ and 70s’ popular music. This is what ELKA said about the Panther Combo Organ in their 1960s’ brochure:

"The PANTHER Combo Organ invites you to a new world of musical excitement. Compressed into her sleek, slender frame is a fantastic variety of thrilling organ sounds. The PANTHER is poised, waiting for your musical commands. Ask her for a biting, swinging attack and she'll leap with ecstasy! Try her on solo and her tingling trebles will penetrate across the biggest room. Taunt this wildcat and her roaring bass tones will overwhelm the noisiest crowd.

The PANTHER's full-throated voice box houses all of the natural sounds of the orchestra, and she'll mix them in an infinite variety of combinations to fit any mood. She's a big theater organ, or a power-packed combo organ, or a pulsating solo organ, ready to respond instantaneously.

Set her up in a couple of minutes and she's ready for action! Rock 'n roll, swing, jazz, or a ballad you name it and this transistorized cat will play it like no other organ in the world."

We agree!

The classic

The ELKA Panther, also known as the Capri, is a classic Italian combo organ of the 60s.

The Panther produces bold, rich organ sounds and has a wide range of tonal variations (13). The Panthers 16', 8', 4' Stops and Mixture voice levels are adjustable. Each note spans over three octaves, there is bass extension into grey keys and separate volume control for bass octave(s). Tone Decay adds percussive effect to Mixture voices. The Panther has powerful vibrato with speed and intensity control.
