Shoom is an expressive XY pad synthesizer. Or, more precisely, three identical synthesizers in one app. It is capable of playing any pitch in the audible range and doesn’t necessarily limit you to a particular scale. Nevertheless, if you do want to use scales, Shoom can deliver anything from common 12-tone equal tempered to xenharmonic and microtonal. Features: • Three independent synthesizers • 8–20,000 Hz pitch range • Slide freely or snap notes to scale with adjustable glide rate • Set notes to infinite hold using a dedicated toggle • Microtonal and non-octave repeating scales support • MIDI note input (including MPE), CC control and clock sync • Optional remapping of MIDI notes to the pitches of the selected scale • Bluetooth MIDI support • Inter-App Audio support with main mix and individual synth outputs • Audiobus 3 support (including AB MIDI) • Ableton Link support • 120+ bundled presets • Import and export of presets and CC maps Synthesizer engine features: • Adjustable polyphony, up to 30 voices • Two oscillators with 4 waveforms and PWM, and one noise generator • Oscillator FM cross-modulation • 4 pole (24 dB/octave) resonant low pass filter with overdrive and pitch tracking • 2 variable slope ADSR envelopes for amplitude and filter cutoff • 2 LFOs with 9 waveforms, up to 3 out of 12 simultaneously assignable parameters, trigger and global running modes, fade-in and phase controls • Y-axis position / MIDI CC#74 as modulation source with up to 3 of 15 simultaneously assignable parameters • MIDI channel pressure / polyphonic aftertouch as modulation source with up to 3 of 15 simultaneously assignable parameters • MIDI velocity modulation of amplitude and filter envelopes • Note pan randomizer • Built-in stereo delay and reverb effects

Features
Read full description

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

Verdict

The call

The clearest difference is update cadence: Moebius Lab at every 3 months against Shoom Synthesizer's every 13 months. Moebius Lab also leads on review sentiment (96% vs 87%). Shoom Synthesizer's advantage is price ($6.99 vs $9.99) and iOS requirement (9.0 vs 17.0). On rating, ratings volume, ads and in-app purchases there is nothing between them.
