• 3-Band multi effects processor • Each band provides its own effect with mix blending control • Comes with built-in effects: Saturator, Lofi and Ring Modulator • Extendable via In-App purchase in Bandit store: Delay and Reverb • Frequency isolator equaliser (DJ style filter) • Two adjustable crossover points for low and high bands with slope up to 48dB • Separate Dry/Wet output controls • Suitable for any situation, going from subtle to drastic change • Multi-outs support, route each band to separate channels in your DAW • Advanced Responsive Design, portrait and landscape views • AuV3 for iOS (iPad/iPhone) FAC Bandit is a multiband audio effect that splits the audio signal into three bands of frequencies according two adjustable crossover points. Each band is processed independently by its own effect processor and the outputs are then recombined to produce the final effect. Each frequency range is altered with different effects and settings that won't sound the same if applied to the full frequency range. As you have probably realized, FAC Bandit is a wonderful and powerful sound design tool for designers who want to sculpt new personal, exciting and outstanding sounds. Either in a subtle way, without compromising the original tone, or in a more drastic way. - AuV3 and Standalone App - To use multiple outputs, you need a host able to provide additional output busses to the AuV3 plug-in The documentation is available at fredantoncorvest.com/FAC_Bandit.html
isxynth
This music effect plugin allows spectral cross synthesis and morphing between two input signals. It separates noise and tone components, offering controls for blending, freezing, and time-based delays. Gestures on controls can be recorded and played back for dynamic sound shaping.
- Spectral cross synthesis
- Morphing between two input signals
- Noise and tone component blending
- Freeze control for spectral blurring
- 3-second delay lines per input
- Gesture recording and playback

isxysnth is spectral cross synthesis / morphing plugin it gets two input signals, splits each one into 2 parts containing noise and tone components and then allows morphing between all these elements. Freeze control allows spectral blurring-like effect for both input signals, two 3 second delay lines allow selection of different signal in time and also provide "freeze" effect you can process left and right channels on stereo source or use this effect as multi-input AUv3 - in that case it will use 2 stereo inputs. Standalone mode currently works only in "mono" mode - three XY controls set balance between tone and noise components, amount of freeze and set up morphing - both inputs have 3-second delay line; freeze button ("*") toggles off recording. - gestures on all the main controls (3 xy pads and two sliders) can be recorded and played back when appropriate button with ">" label is toggled on - in current version standalone app supports only mono (L + R as inputs I and II) processing

Verdict
The clearest difference is rating: FAC Bandit at 4.9 against isxynth's 3.7. FAC Bandit also leads on update cadence (every 4 months vs every 34 months) and ratings volume (57 vs 3). isxynth's advantage is in-app purchases (none vs 5) and review sentiment (100% vs 90%). On ads and device support there is nothing between them.
