Ocean Swift Synthesis has released their entire line of software synths for Windows as free downloads.
The developers note that their products “were a labor of love and our babies” but that they’ve moved on to other development jobs. They add, “We would be very glad if people continue to enjoy them and be inspired by our sound and the passion we put into everything you can find there.”
OSS Enterpris is a hybrid synthesizer exploring Vector, Additive, Subtractive & Wavetable synthesis. Polyphenom is another hybrid polyphonic synthesizer, exploring additive, wavetable, subtractive and fm synthesis – with an extensive array of features, modulations and built in effects. Other free synths for Windows include Aeolian Mediation, an additive synth; Defiant, a hybrid wavetable synth; and Shruti Box, a synth inspired by the traditional Indian drone instrument.
