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

VOSIS is a synthesizer combining audification of greyscale pixel data with several image filters. It is a tool for image sonification, visual music composition, and experimental sound design. The audification of pixel luminance values creates shape-timbre relationships. Pixel scan rate is controlled in terms of note interval, octave, and scale to give varying pitch between image regions. The ADSR envelope allows one to play images as a non-linear sequence of pitches with varying wavetable/timbre. VOSIS Pro adds several features to VOSIS useful for sound designers and musicians: Save and load custom presets, connect a MIDI keyboard and play regions with keys, map any control and region positions to MIDI CC, unlimited recording and screen mirroring with no watermark, downsampling/blur/sharpen, and tremolo filters, subdivide large regions into step sequence mode, load video files (iPad and Desktop versions only).

Verdict

The call

The clearest difference is review sentiment: Moebius Lab at 96% against VOSIS Pro's 67%. Moebius Lab also leads on rating (4.9 vs 4.6) and ratings volume (50 vs 7). VOSIS Pro's advantage is price ($7.99 vs $9.99) and device support (4 vs 1). On update cadence, ads, in-app purchases and monetization model there is nothing between them.

That said, the two scores are not equally well evidenced: Moebius Lab has 50 ratings behind it against 7, so its average is the more settled of the two. Written reviews point the same way: 96% of Moebius Lab's written reviews are positive against 67% of VOSIS Pro's.

UpkeepUpdate frequency

Both ship on a similar rhythm, roughly every 3 months. The most recent releases landed on September 28, 2026 and September 23, 2026 respectively.
