FabFilter 's One Software Plug-In is a professional-quality, aliasing-free, single-oscillator synthesizer with triangle, sawtooth, and square waveforms for Mac or Windows computers. It can be used to create audio in music applications such as studio recording, post-production, DJing, and more.

It has an oscillator and filter that can be modulated by LFO and EG (Envelope Generator) and has adjustable wave balance so that any waveform between sawtooth and triangle can be selected. Additionally, the LFO tempo can be synchronized with the host. The EG has the usual ADSR buttons, but with the ability to adjust the sound. It also has an additional Hold setting that extends the time the keys are pressed.

The One Software Synth plug-in has comprehensive MIDI specifications, including MIDI learning and intelligent parameter interpolation for smooth parameter transitions - no digital clicks or zipper effects, even when you're using MIDI controller changes. The software offers extensive interactive help tips, AltiVec and SSE optimization, and much more. The One is available in VST, VST 3, Audio Units, AAX Native and AudioSuite formats, in 64 and 32 bits, and RTAS in 32 bits.
