The Arp String Ensemble is a fully polyphonic synthesizer designed primarily to create rich orchestral string sounds. The Arp String Ensemble creates the effect of an entire string orchestra,when played through a quality speaker system.

Preset stops select violins, violas, cellos, or contrabass strings, individually or in any combination. A front panel "pitch control" knob allows the String Ensemble to be tuned sharp or flat. Slide controls to adjust the attack and sustain times allow the musician to create the most realistic string sounds.

The cellos and contrabass are played only in the lowest octave and a half on the keyboard. It is therefore possible to play violin with the right hand and cello or contrabass with the left hand. A separate volume control for the bass section permits perfect balance of sound. An expression foot pedal is included with each unit. In addition to the string sound, two horn stops are also provided which simulate trumpet and French horn choruses.

Outputs are provided on the back panel for connection to any kind of guitar amplifier, P.A., organ, etc.
