EP-78 Electric Pianowas designed to create a vintage electric piano feel. It uses subtle tonal changes that are influenced by velocity. This is not a Rompler or Sample-based instrument. It uses various tuned frequencies to achieve its tonal quality. These can be varied using the Timbre control. The effect of the pickup phase is influenced by the Phase control. The Envelope is designed to respond as it would on an Electric Piano and is changed using the Decay control. There is a Treble and Bass control to alter the overall tone of the instrument. The Vibrato section is a simple design and I included an emphasis switch to change the sound of the Vibrato. Emphasis is somewhere between a Phaser and a Chorus and adds a bit more interest to the sound.
