Philicorda is a faithful emulation of the legendary 1960s Philicorda organ. This plugin replicates the transistor-based sound of the later GM751 models, delivering the distinctively warm yet clear tones that made the Philicorda a classic. Like the original hardware, Philicorda features a vibrato circuit, a spring reverb, and two speakers. We have also added some extra features: overdrive, envelope generator, leakage, bias, and key click. Available as AUv3 and Standalone.
