The FM Bundle from Cherry Audio is a bundle of 4 powerful modules and a library of presets for the Voltage Modular software synthesizer that allow you to explore the frequency modulation capabilities of this virtual-modular synthesizer platform. The collection includes FM oscillators and ADSR envelope generators, along with a variety of FM presets to get you started. The Voltage Modular software (available as a free download) runs on Mac and Windows computers as a plug-in or standalone instrument.
