• 3-Band Multi-Effects Processor • Compact design with massive sonic versatility • Each band provides its own effect with mix blending control • Band effects: Saturator, LoFi, Ring Mod, Delay, Reverb, Chorus & Stereo Control • Frequency isolator equalizer (DJ style filter) • Two adjustable crossover points for low and high bands with a slope up to 48dB • Separate Dry/Wet output controls with an optional master Brickwall limiter • Multi-output support: each band can be routed to separate channels in your host • Advanced Responsive Design, portrait and landscape views • Universal Purchase: AUv3 for iOS (iPad/iPhone), macOS and Vision Pro FAC Bandit is a multiband audio effect that splits your audio signal into three independent frequency bands, each processed with its own effect and then recombined to create the final sound. Choose from a set of effects, including saturation, lo-fi degradation, ring modulation, delay, reverb, chorus and stereo control, and blend them precisely within each band. Two adjustable crossover points give you full control over which frequencies are affected, allowing you to shape your tone with precision. By targeting each part of the spectrum separately, you can apply effects in ways that full-range processing simply cannot achieve. FAC Bandit is a powerful sound design tool for musicians who want to craft unique, personal, and exciting sounds, either subtly, without altering the original tone, or in a more creative way. This is an AUv3 Effect and requires a compatible host to work The in-app purchases are for tipping only, the app is fully functional without them Fac Bandit 2 is crafted from a trusted original. Check out the outstanding reviews from Version 1 below: • Great isolated multi band effects, use this one a lot -ChrizzBeatz • Excellent app! Very versatile and the per band FX is such a tasty concept -disbliss • Some apps do what they say they do. Some have a little extra that make you use them more than you thought. This one will constantly keep making you sound better. I thought I would use it for a little color here and there and I now use it at least twice in every track -EduardoG2 • Got all this guys apps and they are all excellent -69reasons • Fonctionnement et ergonomie au top -SoundofSound • One of the most amazing multi band effects you can buy for iOS music production.
