The EK-22 is an analog polyphonic programmable synthesizer from Elka. Its cousin, the EK-44 is a digital and expanded version of the EK-22.

Extended information

Although the EK-22 is analog, the oscillators are digitally controlled (DCOs) for better stability and programmability. The keyboard can be split and there are 16 performance patches to store any split, tuning and patch settings. There are 64 preset and 32 user sound patches of purely Italian style analog synth sounds.

Oscillators are very programmable with syncing, individual tuning, level and modulations. There are two six-stage envelope generators for total control of dynamics. The EK-22 is a capable synth similar to the Prophet 600 in programmability but more like the Matrix 6 in its look and push button style programming interface.
