ARP Quadra

2013-08-16

The ARP Quadra was 4 analog synths in one, with dedicated sections for Bass, Strings, Poly and Lead sounds that could be layered – a quite unique feature when released in 1978. Other notable features were the thick phase-shifting effect from the ARP Omni II synthesizer and aftertouch-like features in the upper part of the keyboard (for leads) and two independent portamento rates for each VCO!
