LFO Tool is an audio effect plugin by Xfer Records for shaping volume, filter and panning changes over time with custom LFO curves. It is widely used for sidechain-style pumping, gating and tremolo effects in electronic music production. The plugin processes incoming audio and can also generate a MIDI message stream for controlling other instruments.
Features:
• Draw custom LFO shapes with a point and tension curve editor.
LFO Tool allows users to quickly and easily design complex modulation patterns for their audio tracks.
- Store 12 graphs in one preset and switch between them with MIDI notes or automation.
• Use up to four graphs at the same time to modulate volume, filter cutoff, resonance and pan.
• Choose graph shapes from a drop-down menu and save your own shapes.
• Set the LFO rate in BPM, with optional swing, or in Hz.
• Keep the modulation in time with the host thanks to sample-accurate sync.
• Send MIDI CC messages to control other soft synths, effects or external hardware.
• Start quickly with dozens of included presets.
• Load the plugin in VST (32-bit and 64-bit), AudioUnit and AAX hosts.
• Use both the Windows and macOS versions, which are included in one purchase.
• Keep the CPU load low, as the plugin is coded entirely in C++.
• Try the demo version, which is limited to 15 minutes, before buying.
• Buy the full version directly from Xfer Records.
LFO Tool is a compact modulation tool for producers who want precise control over rhythmic volume, filter and pan movement. It works inside a digital audio workstation that can host VST, AU or AAX plugins and is not a standalone application. Because the curves are drawn by hand and synced to the tempo, the same plugin can add subtle groove or heavy pumping to basses, pads, drums and full mixes.
