Details:
"The EPS-1 Electronic Piano and Strings, offers six different LED pushbutton-selected piano voices.

Also featured are LED pushbutton selected stereo Tremolo and Chorus effects with variable Speed and Intensity controls. The separately articulated Strings section features touch sensitive attack time, making the EPS-1 the first low cost instrument to offer dynamic articulation of strings.

Each string voice features individual note articulation plus overall Attack and Release Envelope controls, me touch sensitive feature may also be fumed off. Volume, Bass and Treble controls, plus LED push button on/off switch complete the Strings section. The EPS-1 also features a special Key Transpose switch, which allows transposing me entire keyboard up and down a fifth from middle "C", a new piano-type damper pedal, me DS-1, which provides effortless sustaining functions for both piano and string voicings. Rear panel: stereo, mono, separate strings and headphone output jacks and tuning control."
