DarkWave Studio is a free Digital Audio Workstation (DAW) / modular virtual music studio for Windows. You can easily use the built in sequencer, bundled DarkPlug machines and third-party VST effects and VSTi instruments to create music. DarkWave Studio allows the connection of machines in an ad-hoc fashion. The installer ships with both a 32-bit and 64-bit version.
