"HERE THE DESCRIPTIONS FROM PETER FORREST BOOK "VINTAGE SYNTH'S A-Z": Elektronika EM-04 - 49-note (C-C) split multi-keyboard. This seems to have appeared in two very different forms. Both have sets of sliders to the left of the keyboard and in three sections behind it; but one is a neater, flatter machine with a carrying handle at the forot, while the other has fold-down legs, a little Farfisa-like, and a reverse-colour keyboard for the bottom two octaves. Divide-down tone generation; 'slalom' effect. Size: 790 x 490 x 155 mm. Weight: 18kg.

EM-04 HAS A FOUR MAIN SECTIONS OF CONTROL:
1-st GROUP (left manual) - attack, sustain, bass, violin, alto, string, orchestral, brass
BRASS FILTER - attack, sustain (level, on/off), cutoff, resonance
2-nd GROUP (right manual) - attack, sustain, bass, violin, alto, string, orchestral, brass
MASTER - fine tuning, main volume level, tone (brightness), slalom (pitch slide), gavai (finger pitch controller), string/organ select, brass 1-2." Panel translation below.
