Euterpe is a virtual analog synthesizer designed to deliver rich, dynamic sounds through its dual oscillator architecture. Each oscillator features adjustable analog waveforms, including super-saw, square, sine, and triangle shapes. The oscillators can multiply up to ten times each, enabling up to 20 detuned oscillators to create lush, thick textures. This flexibility allows for a wide range of sonic possibilities, from smooth pads to aggressive leads.

The synthesizer includes a multimode filter with resonant lowpass and highpass options, as well as a Moog ladder lowpass variant, providing detailed tonal shaping. Its classic ADSR envelopes govern amplitude and filter behavior, while an adjustable key follow feature adds expressiveness and control. Euterpe also offers monophonic and polyphonic modes, with adjustable glide time for smooth transitions in monophonic play.

To enhance sound design, Euterpe integrates effects such as distortion, reverb, and echo, along with a decimation control that responds to the filter envelope for creative lo-fi textures. A built-in oscilloscope provides visual feedback across adjustable time views, helping users fine-tune their sound with precision. Additional features include preset saving and loading, a clipping indicator, and pulse width modulation on the square waveform, making Euterpe a powerful tool for both beginners and advanced producers.
