Pure-Pten is a virtual analog synthesizer that blends Frequency Modulation, Ring Modulation, Oscillator Sync, Distortion, and Subtractive Synthesis to create rich and dynamic sounds. It offers 10 voices with three oscillators per voice, including 21 waveforms and a unique super wave feature on the third oscillator. The synthesizer is equipped with a multi-mode filter that supports various slopes and filter types, complemented by dedicated ADSR envelopes for both the filter and amplifier sections, allowing precise shaping of the sound.

The instrument features two LFOs, a noise generator, and a six-channel mixer, providing extensive modulation and layering possibilities. Additional sound design tools include a ring modulator, oscillator sync, oscillator FM, and wave distortion functions. It also includes an arpeggiator with adjustable gate time, glide functionality, and the ability to switch between mono and polyphonic modes. Effects such as chorus and a stereo delay with host tempo sync add spatial depth to the sounds.

Pure-Pten enhances workflow with features like MIDI learn, velocity-sensitive controls for both amplifier and filter, a soft limiter, and modulation busses with multiple sources and destinations for intricate modulation routing. The synthesizer supports quick tuning of oscillators and offers options for linear or logarithmic damping in the filter section. With a comprehensive preset library and live function support, it caters to musicians seeking a powerful and flexible synthesizer for diverse musical styles.
