Along with Native Instruments' Reaktor and the closely related FlowStone (previously known as SynthMaker) by DSPRobotics, SynthEdit has been recognised as one of the few tools for independent synthesizer development[1] that don't require traditional programming like JUCE, and the only visual programming environment with 64-bit VST 3 support.
SynthEdit provides a GUI editing system and a full MIDI interface for hardware controllers.
It can export projects as VST plugins, allowing creations to be used as instruments and effects inside of most DAWs[2] and on macOS, where SynthEdit isn't available.
[3] Below a toolbar containing a switch (stylised as a green power button) to start and stop the audio engine, SynthEdit's interface is divided into three vertical sections: a left panel containing a list of modules, a section for the detached visual editing windows in the middle, and a panel showing the highlighted modules' properties and values on the right.
Since its release, the SDK has allowed developers to release additional freeware and payware modules for use within SynthEdit, adding new features to the program like the ability to manipulate waveforms through Fourier transforms (typically used in digital signal processing as the basis of additive and wavetable synthesis engines), new filters and audio effects.
