SynthEdit offers a comprehensive modular environment for creating custom synthesizers and audio effects. Users can design unique soft synths or effect units by assembling modular components through an intuitive drag-and-drop interface. This platform supports the creation of complex signal paths with virtual connections, allowing in-depth sound design tailored to individual needs.

The software supports a wide range of synthesis methods including Virtual Analog, Frequency Modulation, Phase Distortion, and Sampling. It enables the creation of various instruments such as drum synthesizers and effect processors. Additionally, SynthEdit facilitates live performance and MIDI control, making it suitable for both studio production and dynamic live setups.

Once a design is complete, users can export their creations as VST3 or Audio Unit plug-ins, enabling easy sharing and integration into digital audio workstations. The platform also supports multi-channel audio recording and playback, live audio processing, and the use of existing VST plug-in instruments and effects, providing a flexible and powerful tool for sound designers and musicians.
