ARP Quartet

ARP Quartet is a virtual instrument developed by Arturia, a French music software and hardware company. It is a recreation of the classic ARP 2600 synthesizer, which was used by many famous musicians such as Stevie Wonder, Kraftwerk, and Jean-Michel Jarre.

The ARP Quartet is a four-voice polyphonic synthesizer that allows users to create complex sounds and textures. It features two oscillators per voice, a low-pass filter, an envelope generator, and an LFO. It also includes a step sequencer, arpeggiator, and a modulation matrix. The ARP Quartet also has a built-in effects section, allowing users to add reverb, delay, chorus, and other effects to their sounds.
