Elsita is a soviet analog drum synthesizer produced from 1989 until 1991, when RMIF went bankrupt.
Although being released in a pretty late period, the Elsita was built following old standards from the mid 70's/early 80's : fully analog, trigger-only, with big knobs.
The Elsita has 4 channels, which are not perfectly identical, at least on my model. It sounds more like a A/B/A/B disposition (As the colors suggest actually), but they all have the same parameters.
