Stock Synth Instruments in FL Studio
FL Studio on Windows includes several powerful stock synthesisers that do not require any additional purchase. The three most used for melodic production are 3xOsc (triple oscillator synthesiser), Sytrus (FM/subtractive hybrid) and Harmor (additive/resynthesis).
Synth presets for these instruments save the complete plugin parameter state as a preset file you can load in any FL Studio project on Windows, instantly recreating the configured sound without manual setup.
3xOsc Presets in FL Studio
3xOsc is a triple-oscillator synthesiser built into FL Studio. It generates audio from three simultaneous oscillators, each with a selectable waveform, pitch offset and volume control. Presets for 3xOsc are most useful for sub-bass layers, simple pad stabs and basic melodic leads.
The 3xOsc sub bass preset in this collection uses a sine wave oscillator detuned slightly with an amplitude envelope set to a moderate attack and slow release for a sustained sub-bass character typical of trap and hip-hop productions on FL Studio Windows.
Sytrus Presets in FL Studio
Sytrus is an FM (frequency modulation) and subtractive synthesiser included with FL Studio. It is capable of producing complex tonal textures, plucks, pads and leads. FM synthesis can produce sounds with rich harmonic content that pure subtractive synthesisers like 3xOsc cannot achieve.
Sytrus presets in this collection include a pad preset with slow attack and soft release, a pluck preset with fast attack and short decay for melodic note triggers, and a chord stab preset for chord pad use in the Piano Roll.
How to Load Synth Presets in FL Studio
Open the synthesiser plugin in the FL Studio Channel Rack by double-clicking the instrument channel. In the plugin interface, look for the preset browser or load button — in Sytrus it is the preset dropdown at the top of the plugin window. In 3xOsc, drag and drop preset files onto the plugin interface or use the preset selector.
