"Was made in July 1988 by Riga`s Music Instruments Factory (RMIF). Elsita has four independent and identical channels of analog drum synthesis that can produce really fat and original analog drum sounds. You can trigger it from drum pads (triggers) or from any audio out - drum machine, analog output of soundcard etc. As other soviet devices Elsita has it`s own unique character that will be great for any sound design experiments!
