Molli Looper is a realtime stereo effect for looping and filtering. Intended mainly as a live performance tool, no preparation is needed to trigger loop recording - input is constantly recorded in the background to be triggered whenever it is needed.   Loop timing is synced to host clock, and can be adjusted from multi-bar loops right down to 16th note drills.   The looped or unlooped audio is then passed though a lowpass -> neutral -> highpass resonant filter, based on a 4 pole ladder design for lush analogue style sound.   You can use Molli Looper either as iOS Standalone app or as AUv3 plugin. FEATURES: - Combination of looper and stutter/freeze - Continuous recording: instant recording/looping - Runs in sync with host clock - Jumps to meaningful places in the recording: "Snap to grid" - Grid: 1/16, 1/8, 1/4, 1/2, 1, 2, 4, 8, 16, 32 beats - Ability to scroll through the recording - Lowpass/highpass resonant filter - Long Tap XY keeps filter position - Limiter/booster effect - Momentary Mode - Tap on Molli Looper icon for basic information

Hybrid reverb with an artificial space designer, combining it with algorithmic reflections tail processing, is ideal to creating immersive ambience of deep spaces, lush atmospheric textures or stunning whispering backgrounds in your ambient, electronic, experimental and sound design projects. Unlike traditional algorithmic reverbs, Stellarvox constructs a complex model of a vast resonant sound spaces with choice of geometry, dimensions and tonal structure of the space, along with a unique feature that dynamically change the timbre of reflections over the reverberation time. The second algorithmic reverb allows you to prolong and blur reflections, adding extra dimensions to the sound space. Easy-to-use controls on a single screen, along with optimally designed parameters that always give great results, make insignificant the peculiarity of that kind of reverbs, when the model creates with a little delay after changing it. Factory presets and the random feature will give you a starting point of inspiration and allow you to get a quick result where you need just to slightly tweak the parameters to align with your idea. This application is great for ambient projects, it can create mesmerizing atmosphere from single infrequent sounds of various instruments, or giving a beautiful and deep backgrounds to sharp sequences in electronics, as well as for any experimental projects that require unusual, deep and rich sound ambience.
