TURN A NOTE INTO SOMEWHERE ELSE. VESPER is a stereo delay and reverb playground for iPhone and iPad. Start with a tight rhythmic echo, stretch it into a suspended room, then pull the sound apart with your fingertips. Use it as a standalone effect or load its AUv3 extension in a compatible music app. TOUCH THE SOUND Open Wave Field and the pedal unfolds into three interactive surfaces: TIME, SPACE and FRACTURE. Drag to reshape connected groups of parameters, from repeat spacing and feedback to room size, pitch and memory. Depth controls add another dimension. Keep the transformation, restore your starting point, or save a new preset. TWO ENGINES. MANY DIRECTIONS. Combine six echo arrangements with eight space voices. Explore pitch-shifted trails, reverse textures, stereo cross-feedback and moving diffusion. Choose how the engines feed each other, place processors across ten insert slots, and move between host-synced subdivisions and free timing. SOUNDS THAT KEEP MOVING Six modulation sources, a sixteen-step sequence and twelve modulation routes bring motion to your sound. The BECOME control performs a dedicated transformation in each factory preset. Freeze a texture, ride the mix, or use Memory Glass to introduce pitched fragments of recent audio. 100 PLACES TO START The included factory collection ranges from Impossible Rooms and Clockwork & Trouble to fractured rhythms, altered gravity and long-form textures. Search sounds by name, collection or tags, mark favourites, compare A/B states, and import or export your own presets. BUILD A PHRASE Capture up to 20 seconds of stereo audio in the iOS looper. Add up to three layers, adjust their levels, reverse playback or switch to half speed. Choose where the loop records and returns in the signal path. MADE TO PLAY A detailed pedal interface brings the main sound controls within reach, with a multifunction display for deeper editing. Dry/Wet and output makeup gain let you place the effect around your source. Wave Field turns sound design into a performance gesture. INCLUDED • Standalone app and AUv3 audio effect for iPhone and iPad • Stereo delay and reverb engines with flexible routing • Interactive TIME, SPACE and FRACTURE surfaces • 100 factory presets with individual BECOME transformations • Modulation, step sequencing, pitch and memory processing • Three-layer stereo looper • Preset search, favourites, A/B comparison and import/export Requires iOS/iPadOS 16 or later. AUv3 operation requires a compatible host app, available separately. Standalone live input requires microphone permission; headphones or an audio interface are recommended.
