WAIL

What it does

A feedback drone synthesizer for iPhone and iPad, standalone and AUv3. A self-resonating loop of two feeding-back delay voices is shaped by four XY pads (Feedback/Filter, Bite/Space, Ring/Fold, Comb/Sub) and knobs for Master, Spread, Grind and Tune, with a live oscilloscope. It runs as an evolving drone or takes MIDI notes, and all 12 parameters accept CC learn.

In the demo

Jade runs it in AUM, starting with every control zeroed to show that nothing sounds until the host transport runs, then drags across each pad to pull out vowel-like screams, bit-crushed grind and sub. She sends an LFO to the tune knob and feeds it notes from Melody Bug to play it as an instrument.

Worth knowing

Jade keeps a limiter after it and her interface turned down, as levels jump quickly. There are no presets inside the plugin; state is saved with the host project, which the developer describes as intentional.
