These envelopes control different effect parameters, and can be drawn freely or onto a grid. The envelopes are looped, while the incoming audio isn’t (unless you’re feeding it looped material of course). This is a powerful & fun way of altering your sounds to a whole new level, sometimes not even recognizable! Thanks to the looping nature of the plug-in, it will fit very well into any musical context. One way of using it would be to revitalize any looped material within a few seconds. Noteworthy features: • Volume envelope • Low cut filter envelope (with resonance) • High cut filter envelope (with resonance) • "Glitch" envelope (alters timing) • Delay send envelope (with tempo synchronised time, filter and feedback • IAA (With tempo sync if host sends it) • MIDI clock sync • Load / Save presets • Audiobus • Documentation (on the product web page) Check out the product web page for a video demo.

If I’m being honest, not making this an audio just isn’t smart at all. -- Strizbiz, 2020-09-14 ### ***-- "AuV3 = * * * * *" AuV3 = * * * * * AuV3 = * * * * * AuV3 = * * * * * AuV3 = * * * * * AuV3 = * * * * * AuV3 = * * * * * AuV3 = * * * * * AuV3 = * * * * * AuV3 = * * * * * AuV3 = * * * * * AuV3 = * * * * * AuV3 = * * * * * AuV3 = * * * * * AuV3 = * * * * * AuV3 = * * * * * AuV3 = * * * * * AuV3 = * * * * * AuV3 = * * * * * AuV3 = * * * * * AuV3 = * * * * * AuV3 = * * * * * AuV3 = * * * * * AuV3 = * * * * * AuV3 = * * * * * AuV3 = * * * * * AuV3 = * * * * * AuV3 = * * * * * AuV3 = * * * * * AuV3 = * * * * * AuV3 = * * * * * AuV3 = * * * * * AuV3 = * * * * * AuV3 = * * * * * AuV3 = * * * * * AuV3 = * * * * * AuV3 = * * * * * AuV3 = * * * * * AuV3 = * * * * * AuV3 = * * * * * AuV3 = * * * * * AuV3 = * * * * * AuV3 = * * * * * AuV3 = * * * * * AuV3 = * * * * * AuV3 = * * * * * AuV3 = * * * * * AuV3 = * * * * * AuV3 = * * * * * AuV3 = * * * * * AuV3 = * * * * * AuV3 = * * * * * AuV3 = * * * * * AuV3 = * * * * * AuV3 = * * * * * AuV3 = * * * * * AuV3 = * * * * * AuV3 = * * * * * AuV3 = * * * * * AuV3 = * * * * * AuV3 = * * * * * AuV3 = * * * * * AuV3 = * * * * * AuV3 = * * * * * AuV3 = * * * * * AuV3 = * * * * * AuV3 = * * * * * AuV3 = * * * * * AuV3 = * * * * * AuV3 = * * * * * AuV3 = * * * * * AuV3 = * * * * * AuV3 = * * * * * AuV3 = * * * * * AuV3 = * * * * * AuV3 = * * * * * AuV3 = * * * * * AuV3 = * * * * * AuV3 = * * * * * AuV3 = * * * * * AuV3 = * * * * * AuV3 = * * * * * AuV3 = * * * * * AuV3 = * * * * * AuV3 = * * * * * -- StarvedArt, 2019-10-22 ### *---- "Doesn’t Work" Running it in Cubasis through IAA on my fully updated iPad Pro. Does not work at all. It’s a shame because their other apps, especially Korvpressor, are great. -- Urbvac, 2018-05-27 ### ***-- "Updated review" This app works great now as IAA. This would be top notch as an au. Request to developer, please implement a gate mode triggered by midi notes. -- qwesterish, 2018-03-08 ### ***** "Tempo based wackiness" This is a great tool for filtering and twisting live and recorded audio. I am in love with the time/pitch stretch feature! Give that added bit of analog wobble to your music... Just give it a try. Worth every penny -- djAlpad, 2015-12-03 ### ***** "Way Cool" Try this: run a simple tone, like from The Oscillator, into Audiobus through Kuvert as an effect. Play. Turn that tone into "sequenced" glitchy awesomeness. :-D -- Modravoda, 2015-11-30 ### *---- "Crap app!!!"
