DarkWave natively supports both x86 (32-bit) and x64 (64-bit) versions of Windows with native binaries compiled for each platform. The x86 and x64 versions can each only load plugins for that platofrm, i.e. the x64 version only loads 64-bit VST and DarkPlug plugins.

DarkWave supports multiple processors well, with an aggressively multithreaded audio path that can utilize multiple processors or cores by multithreading. The program soars on a Pentium D Système with Windows XP 64-bit Edition.

The following plugins are included with DarkWave: MIDI Input, ES BrainSynth (Virtual Analog Subtractive Synth), ES SpatialVerb (Room Modelling Reverb Unit), ES DrumKit (Virtual Analog 909), ES Delay (Echo Effect) and ES Kick (Rave Kick Generator).
