Cube Synth is a groundbreaking new software instrument giving you the power and flexibility of additive synthesis together with easy editing and morphing capabilities. Macro parameters allow you to control this beast with unequalled ease. Intelligent sound morphing capabilities enables you to easily create complex evolving sound scapes, vocal phrases or stunning rhythms simply by choosing up to four sound sources from a predefined set. Then add one of the predefined envelopes and a unique, complex sound preset containing thousands of parameters is created! If you want to dive deeper into the inner secrets of this synthesis monster you can manipulate each parameter individually to get precise control over the sound. A number of high level parameters such as Brightness and Harmonic spread control hundreds of synthesis parameters in a way modeled after the inner workings of natural instruments. Cube Synth gives you also a new method of getting randomly generated sound patches in a way you never experienced before: roll the dice! Every single try gives you a new unique sound patch, really every try, promised… Synthesis • over 400 sound presets • four morphable sound sources • up to 512 partials per voice • harmonic/inharmonic spectra • arbitrary noise spectra • morphable filter banks • 3 Envelopes with tempo sync • 64 time/level segments per envelope Arpeggiator • Uses programmable sequences with up to 32 steps. • Can trigger single notes and chords. • Unique randomizer generates Arpeggios with 100% usability. • 32 Arpeggios included, unlimited useer arpeggios possible. • For each step you can program tie, accent, transposition and note order Effects • Chorus • Phaser • Overdrive • Ensemble • Echo/Delay • Reverb Global • Audiobus 2 compatible (Input slot) with state saving • Support for Ableton Link. • Inter-app audio compatible (Instrument/Generator) • CoreMIDI / Virtual MIDI • Audio recorder with Metronome. • Upload to SoundCloud and File Export. • Audio pasteboard.

Syndt is a high quality polyphonic synthesizer with a lot of possibilities. The oscillator waveform can be morphed between pure sine to pure square and supports alternation of pulse width. Both the shape and pulse width can be modulated by two independent LFOs. Finetuned low pass and high pass filters combined with a separate filter attack setting (optionally based on velocity) makes possibilities to create some raw and interesting sounds. The additional LFO can be shaped exactly as the oscillator, and optionally controls filters, gain and pitch (using a modulation wheel or just automatcally). This LFO can be synchronized to a AUv3 host. Globally there’s a nice stereo chorus, ping pong stereo delay (that also can sync to a AUv3 hosts bpm) and EQ. Key features: * AUv3, works with AUv3 compatible hosts like GarageBand, Cubasis, Auria, AUM etc. * 70 professionally made presets * XY pad based oscillator and LFO (PWM on the X axis and morphs between sine and square on the Y axis) * Independent mini-LFO (sine only) for each axis of the oscillator XY-pad. * LP / HP filter with resonance * LP Filter can be velocity sensitive * LP Filter has an optional attack time * LFO can affect LP filter, HP filter, gain level and pitch * LFO has an optional attack time * LFO can be syncronized with an AUv3 host (AUv3 mode only!) * Ping pong stereo delay (optionally syncs to host) * Stereo Chorus * Three band EQ * Legato mode with glide speed parameter * Pitch bend range OBS! Syndt oversamples the signal and uses sophisticated DSP features which makes it consume quite some CPU. An iPad AIR 2 or better is recommended if you’re planning to use many voices simultaneously.

Verdict
The clearest difference is rating: Cube Synth at 4.7 against Syndt's 3.9. Cube Synth also leads on price ($1.99 vs $8.99) and update cadence (every 4 months vs every 16 months). Syndt's advantage is chart position (#193 vs unranked) and device support (3 vs 1). On ratings volume, ads, in-app purchases and monetization model there is nothing between them.
