“Italian made GRP A-4 Analog Synthesizer
Offers 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, Glide, 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.
The reviews say the A-4 blows away the Moog Voyager XL. The GRP has much more power and flexibility and the fidelity is superior to the Voyager. If you are looking for a Model-D sound, then buy a Model D, cause even Moog’s re-issue doesn’t sound like a D to many. The GRP is not a Moog clone.
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.
The cabinet appears to be a walnut veneer. Other than that, the unit looks brand-new. I am third owner. None were smokers, home studio only, never live gigged, super low hours. I only had it a week before urgent medical bills appeared from my daughters ear surgery. :(“ Click here to search for synths on eBay
