PanCake is a free plugin for most flexible panning modulations
You can build your own modulation curves. They can be easily drawn using soft or hard control points, thus producing smooth transitions or sharp curves in the waveform.
PanCake’s LFO can be synced to your DAW, from a quick 1/128 note modulation up to 32 bars. It can also be set to operate freely from 0.02 Hz to 5.24 kHz, and can be MIDI triggered.
An accurate left/right channel volume display provides useful visual control.
Best of all, PanCake is completely free. No login or registration is required. Download it now.
