k1 is a straightforward synthesizer created to introduce users to the fundamentals of synthesis. Its design focuses on clarity and ease of use, making it ideal for beginners who want to understand core synthesis concepts without being overwhelmed by complexity. The interface guides users through essential sound-shaping elements, providing a hands-on learning experience.

The instrument features a single oscillator capable of producing seven distinct waveforms, offering a variety of basic tonal options. It also includes a unison mode that layers two oscillators, enriching the sound with added depth. A multi-mode filter with its own modulation envelope allows for dynamic tone sculpting, while an LFO with three modulation targets adds movement and variation to the sound.

Additional sound design tools include a VCA with a full ADSR envelope, giving control over amplitude dynamics, and built-in chorus and flanger effects to enhance texture and space. The preset bank is designed to be educational, walking users through each section of the synth and demonstrating how different parameters influence the overall sound. This combination of features makes k1 both an effective learning tool and a capable instrument for simple sound creation.
