"Italian made GRP A-4 Analog Synthesizer.
Main Features: (3) full-feature oscillators, plus (2) discrete LFO's. S&H, Noise, Mixers, (2) ADSR, 16-Step sequencer, A-440 generator, 12dB State variable filter and 24dB Low pass filters, portamento, Auto-pan, accepts external signals, Stereo Headphone TRS jack. CV/gates in and out. MIDI and USB in rear. Complex routing features: provides virtually the same flexibility of a modular without the need for patching. The A-4 is single-voice, and does not store patches.
Audiophile timbral quality. Truly holds its own with ANY other synth. One of the most beautiful synths ever made.

This is one HELL-of-a synthesizer, semi-rare. Will retain its value; so buy it, use it, then sell it for what you paid for it. This a unique opportunity."
