ADHDidi is an additive synthesizer designed to deliver rich, complex sounds by layering 16 sine waves tuned to the fundamental frequency and its first 15 harmonics. This unique approach allows for detailed sound shaping, offering users the ability to craft intricate tonal textures with precision. The synth features waveform activation, cascade sync, and a powerful state variable filter with low pass and high pass options, enhancing its ability to create dynamic audio landscapes.

Equipped with 32 eight-stage envelopes, ADHDidi provides extensive control over both pitch and volume across the individual sine waves. Each envelope offers customizable curves and stages, allowing for nuanced modulation and expressive sound design. The filter cutoff can be modulated by any of these envelopes, with adjustable resonance to further sculpt the sound. Additional effects such as delay with adjustable rate, feedback, and mix settings contribute to a fuller, more immersive sonic experience.

ADHDidi supports both mono and polyphonic modes, with features including glide, velocity control, pitch bend range, and MIDI channel configuration, making it adaptable to various playing styles and setups. Designed to reward user feedback and engagement, this synthesizer combines technical depth with user-friendly controls, encouraging exploration and creativity in sound design.
