How it works

DroneSynth is built around three oscillators feeding a shared filter and envelope, with two LFOs and a delay/reverb send for movement and space.

• OSC — pick a waveform (sine, triangle, square, saw, or pink noise) per oscillator and tune its volume, octave, semitone, and fine pitch.
• ADSR — shape how each note attacks, decays, sustains, and releases.
• LFO — two low-frequency oscillators modulate filter cutoff and pitch for evolving, animated textures.
• Delay & Reverb — tap out a tempo on the delay, bounce it ping-pong across the stereo field, then wash it through Room, Hall, Plate, or Cathedral reverb.
• Drone — toggle Drone mode to sustain a chord indefinitely without holding down keys, ideal for ambient beds and long-form textures.
• Keyboard — play from the on-screen keyboard, with adjustable range and octave for reaching exactly the register you want.
• Presets — save and recall as many patches as you like from the Presets panel.
• Stereo Filters — an optional one-time purchase that splits the Moog Ladder filter across the left and right channels for wider, more spacious tones.
