Harmonia Synthesizer

Harmonia is a wildly innovative virtual instrument from Cherry Audio, designed to create the rich, evolving polyphonic tones often associated with vector and wave sequencer synthesizers of the 80s and 90s, but through a more effortless and visual technique.


The magic behind Harmonia lies in its unique approach to the heart of any synthesizer, the oscillators. Using techniques like those found in additive synthesis, each Harmonia oscillator can simultaneously produce up to eight pitches, individually tuned to a harmonic series or semitones. The volume for each pitch harmonic can be fixed or dynamic, and interpolated harmonic scanning enables dramatic sweeps and melodious sequences. Distinguishing Harmonic Level orange bars and red meters provide real-time feedback.

Harmonia derives its distinctive sound from a carefully curated collection of sampled waveforms sourced from various synthesizers, traditional instruments and voices, colorful “lo-fi” sounds, and more. Most samples are stereo, making their overtones expansive and organic without further processing. In addition to its hundreds of onboard waveform samples, user samples can be imported, further expanding Harmonia’s tonal palette. Producers can create a vast multitude of unique morphed and sequencer-like tones simply by altering waveform selection and the 29 onboard harmonic presets, and new sets can easily be customized and stored in an independent memory bank.

Beyond its harmonic oscillators, Harmonia includes more familiar but enhanced synthesis tools such as four syncable polyphonic LFOs with one-shot and retrigger and ten waveforms; a stereo multimode filter with lowpass, highpass, bandpass, and notch modes; click-and-drag ADSR filter and amp envelopes; and a massive mod matrix with eight slots for 19 sources and 80 destinations.

Harmonia has the extra touches Cherry Audio is known for, including support for aftertouch, flexible MIDI mapping, and its intuitive preset browser stocked with over 350 breathtaking and professionally designed presets. Harmonia also includes 17 studio-quality effects such as distortions, chorus, phaser, rotary speaker, echoes, and reverbs, all fully modulatable through the mod matrix.
