The Electro-Harmonix KEY9 Electric Piano Machine transforms the sound of a guitar or keyboard into convincing electric piano and percussion tones using EHX's polyphonic tracking engine. It offers nine presets covering classic Rhodes and Wurlitzer voices, including a Dynamo setting that nails the modded Dyno My Rhodes sound that ruled the 1980s, a Wurli preset for the instantly recognizable reed-piano tone, and an Eighty Eight setting emulating a Rhodes 88 with tremolo, plus more unconventional voices like vibraphone and steel drums. Dry and effect blend controls and attack and tone shaping let players dial realistic key sounds. With excellent tracking refined from the earlier B9 and C9, it suits guitarists wanting authentic electric piano textures for studio layering, ambient pads, and live keyboard emulation without a keyboard.
