This keyboard features semi-analog sound and semi-analog percussion, enhanced by versatile drums rhythm slide switches and accompaniment.
The coarse multipulse square wave timbres provide a distinctly cheesy sound.
While it shares many similarities with the Casio MT-500, the instrument differentiates itself with semi-analog percussion rather than sample-based sounds.
It also lacks the drum pads and drum trigger inputs found on the MT-500. The timbres produce a more coarse multipulse square wave sound, which, although less refined, adds a nicely cheesy character.
In 1988, the MT-52 was listed in a German Conrad catalog at 299 DM (approximately 150 €), and a white version was also available.
