What is 3xOsc ?
” 3xOsc is a deceptively powerful 3-oscillator, subtractive synthesizer feeding the FL Studio Sampler. Its purpose is to generate a bright sound to be filtered by the channel’s instrument tools. It can also produce its own kind of stereo phasing.
To reduce CPU load the oscillators are anti-aliased during rendering only. This means the rendered tracks may sound better, but rendering will be slower.” Image Line
