Moebius Lab is a multimorphic sound processor which contains a synth, a varispeed stereo sample player, 9 time domain effects, 6 spectral effects, 7 slots for external audio application, and nearly 200 LFOs that can modulate each parameter. You can move the effects along two chains, and get endless combinations of incredible sounds. ALL the App parameters can be modulated with dedicates LFO (one independent LFO for each parameter!). To get you started, you have more than 200 ready-mades presets. Each effect has an in-line help with an explanation of the parameters. The screen is divided into 3 horizontal areas: the top one contains the sound source (Sample player/External Input/Internal Synth), the middle one contains the Time Domain Effects Chain with four slots for external apps, the bottom one contains the Spectral Effects Chain. The two effect chains are connected in a sort of Moebius Ring: you can route the signal from the Time Domain Chain to the Spectral Chain and vice versa. You can even add up to 7 IAA effects and/or instruments, the number of possibilities is huge! *** LIST OF EFFECTS (NODES) *** - EXCITER The Exciter Node distorts the signal below (Saturation) or above (Excitation) a given frequency. - RINGER A ring modulator with distortion and feedback. - KLAMPER Clamps the signal with some special features. - SWARMER A “superchorus”, excellent to create super fat synth sounds (and more). It is composed by a chain of modulated delay lines. - FILTER The Filter node has two configurations: Dub: dual low-pass high-pass state variable filter with resonance and overlap factor. Morph: a triple low-pass/band-pass/high-pass state variable filter with resonance and continuous morphing between the filter types. - SPLITDEL A dual band delay with feedback. - REDUKTOR This node can be used to decimate and do other “bad things” to your signal. - SHIFTER A dual band frequency shifter. - REVERSO Plays the signal in reverse at regular rate. - BRICKWALL A spectral brickwall filter. - GRIP This node samples and holds spectral components of the incoming signal, based on their amplitude. - BLUR A (noisy) “spectral reverb”. The duration of the spectral components is prolonged (blurred). - DEGRADER A spectral decimator. - FLUTTER Flutter is a sort of animated brickwall. Two spectral sinusoidal LFOs define the frequency boundaries. The spectral components which are inside or outside (depending on the Spectral Balance) these boundaries are suppressed. - PLATEVERB As the name suggests this is a classic Plate Reverb. - DYNAMICS PROCESSOR You can change the output sound using a compressor and expander effect. This is used to either reduce or expand the dynamic range of an audio signal. THE SYNTH The internal synth contains two band limited oscillators, a complex oscillator, a ladder filter, an envelope generator and a sub-bass oscillator. Other Features: - Audiobus and Inter-App Audio support (sender and FX) - Built-In Stereo Sampler with varispeed - Control Manager LFO for Parameters - Midibus, Virtual Midi and Network: 14 bit NRPN controllers - File Manager, sharing common audio files via iTunes, Dropbox and AudioCopy - Snapshots Presets Morphing Pad
midiGATEs
This app introduces randomness to MIDI note streams, selectively muting notes to create sparser, more dynamic musical patterns. It offers multiple modes for controlling muting probability based on note, scale, or sequence position.
- Random MIDI note muting
- Four distinct muting modes
- Gate On/Off Repeats for dynamic control
- Note-specific muting percentages
- Sequencer-based muting patterns
- CoreMIDI and AUv3 support

midiGATEs midi probability is an Audio Unit v3 MIDI Effect and CoreMIDI capable app. midiGATEs listens to MIDI input and based on random chance mutes some of the incoming notes to make a busy, repetitive stream of notes a little more interesting and sparser. It has four modes: Gate Mode - One set percentage to be muted for all notes. Also includes Gate On Repeats (when a note passes through unmuted, also pass through X more notes after) and Gate Off Repeats (when a note does not pass through the gate, also mute the next X notes) to make things a little more interesting. Note Mode - Each note in the scale (C, C#, D etc) has its own percentage chance to mute incoming notes. Sequencer Mode - Every eight notes has a different percentage chance to be muted. Can also change the sequence length to be less than eight. Thru Mode - Nothing is muted, normally not used but there if you need it. If midiGATEs is inserted as an AUv3 MIDI effect in a supported host such as Audiobus or AUM it should setup and work automatically. If you wish to use it without an Audio Unit host you can toggle the CoreMIDI input and output and use it that way.

Verdict
The clearest difference is price: midiGATEs at $3.99 against Moebius Lab's $9.99. midiGATEs also leads on device support (3 vs 1) and iOS requirement (11.4 vs 17.0). Moebius Lab's advantage is ratings volume (50 vs 13). On rating, review sentiment, update cadence and ads there is nothing between them.
