Volume Pedal is an AUv3 audio effect and MIDI controller helper designed to remove the awkward quirks of using expression pedals and other continuous controllers inside an AUv3 host or DAW. Most hosts can map a swept controller to volume, but their native controls are often fiddly, imprecise and scattered across automation menus. Volume Pedal puts the important controls in one clear interface, making it much faster to create an accurate and predictable response. It works with any continuous or swept controller, including expression pedals, breath controllers, faders, knobs and other MIDI control sources. Set the heel and toe limits, choose a response curve, refine its shape and reverse the movement when needed. The visual response graph shows exactly how controller movement will affect the output, allowing precise adjustments without repeatedly digging through host settings. Volume Pedal is especially useful when: • Your controller reaches full volume too quickly • Most of the useful range is crowded into one part of its travel • You need a quieter minimum level without going fully silent • You want a softer or more aggressive response • The controller direction needs to be reversed • Native DAW or host controls are too limited or cumbersome • You want consistent, automation-friendly control inside the box Features include: • AUv3 audio effect for iPhone, iPad and Mac • Compatible with AUv3 hosts • Works with expression pedals, breath controllers, faders, knobs and other swept MIDI controllers • Adjustable heel and toe levels • Multiple response-curve types • Shape control for fine-tuning the response • Reverse control • Clear visual response graph • Smooth real-time control • Host automation support • Universal purchase across compatible Apple devices Volume Pedal is not an amp, instrument or traditional stompbox effect. It is a focused AUv3 control utility that sits inside your signal chain and helps your MIDI controller behave the way you expect. Whether you are controlling guitar volume, synth dynamics, ambient swells or any other level-based performance, Volume Pedal provides a quicker, clearer and more precise alternative to configuring the same behaviour with native DAW or host controls.
