VPT's built-in LFOs automate any routed parameter with sine, ramp, triangle or square waves

VPT includes up to 10 LFOs (low-frequency oscillators) that generate continuous waveforms to drive parameters through the router. Each LFO has a wave shape (sine, ramp, triangle, square), speed, phase, range (amplitude), value offset and an invert switch. You give the LFO a controller number in the LFO tab, then map that controller number in the router to any destination parameter. Speed and range can themselves be set via OSC (/1lfo/speed, /1lfo/range) for meta-automation. LFOs provide motion without manual control, which is what makes unattended installations or hands-off ambient sets possible.

Examples

Set LFO 1 to sine, speed 0.5, range 0.8, give it controller 1, then route ctrl 1 to layer 1 fade 0.–1. so the layer slowly pulses in and out.

Assessment

Configure an LFO so a layer’s transparency oscillates between about 20% and 100% roughly once every 4 seconds. Which wave gives a smooth fade in/out versus a hard on/off?
