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
