Arpeggist is a MIDI Note arpeggiator with a very flexible step matrix editor for programming and a unique “rolling dice” random arpeggio generator. You can build arpeggios from scratch or use one of the factory arpeggios as foundation. You can also create an unlimited number of user arpeggio presets. Just play a chord or a single note and it gets transformed into a grooving monophonic synth line or a rhythmical chord pattern. Full featured programmable Arpeggiator • User programmable sequences with up to 32 steps. • Can trigger single notes and chords. • Unique randomizer generates Arpeggios with 100% usability. • 40 Factory arpeggios included, unlimited user arpeggios possible. • For each step you can program tie (bound notes), accent, transposition and note order • Use to control MIDI compatible Synthesiser Live • Play trigger notes live with the onscreen keyboard. • Optionally use CoreMIDI compatible hardware keyboard. • Chord generator plays complex chords on one finger playing. • Internal sound generator. • Selectable Arpeggiator MIDI Output port. • Dozens of scales selectable • Variable Keyboard layout for scale optimized playing Global • Audiobus 2 compatible (Input slot) with Preset saving. • Inter App Audio • Exchange user presets with File Sharing in iTunes. • Support for virtual MIDI input/output connections.

RingsFX is an AUv3 plugin based on the famous Mutable Instruments Rings, one of the most dedicated and fully-featured Physical Modeling Eurorack modules ever created. At its core is a resonator that needs to be 'excited' or 'strummed' by MIDI input, noise, or external audio excitation. RingsFX emulates vibrations of structures simulated by 3 different synthesis techniques that can be plucked or process external signals: Modal Synthesis, Sympathetic Strings, and Inharmonic Strings. Traditionally, Rings was only monophonic but used a unique approach to polyphony that allowed the previous note to 'ring' out and decay while a new note was played. Rings FX provides these same modes (Mono, Duo, and Quad), but expands it with a true Polyphonic mode. RingsFX also expands the capabilities of the original engine by adding support for velocity sensitivity and MIDI MPE mode. The new polyphonic mode allows RingsFX to play up to 12 notes of true polyphony, depending on the settings. Doing so requires RingsFX to use multiple Rings resonators, but the more true polyphony you use, the more processing power it requires. Running in the traditional Monophonic, Duophonic, or Quadrophonic modes may be preferred in order to keep CPU usage under control. RingsFX has 7 modes in total, by combining the 3 basic modes with additional properties such as chords or specially tuned reverbs. The original hardware also had a secret 'Easter Egg' mode, which in RingsFX is simply calling 'Synthesizer' mode, rumoured to be based on one of the early Korg synthesis methods. This mode supported a number of mutable effects which now work on in all resonator modes. RingsFX also has a Mod-Matrix which allows you to combine the built-in LFOs and FEGs to great effect by manipulating parameters and mutable effects in realtime. Finally, RingsFX can be loaded as an AUv3 effect plugin. Set the Exciter Source to 'INPUT', and you can pass any audio through RingsFX and use this audio as an external exciter. For example, it can be used to great affect on a drum beat to create some crazy rhythms. Use the Output Mix to combine the original audio with the synthesised resonator output to create some stunning effects. Features ○ 7 unique synthesis modes. ○ Supports Mono, Duo, Quad and true polyphony. ○ Supports 2 fluid LFO's per note. ○ Up to 4 FEG's per note. ○ External Exciter modes. ○ White noise Pulse Sequencer. ○ Supports 6 mod-able effects and 6 global effects. ○ Mod Matrix ○ Input and white noise filters. ○ Program Manager with drag and drop. ○ Preset Search and Favourites. ○ Easy export and import of banks and presets. ○ Extensive help manual. ○ Web Transfer for backing up to PC/Mac. ○ MPE Support.

Verdict
The clearest difference is review sentiment: RingsFX at 100% against Arpeggist's 14%. RingsFX also leads on rating (4.9 vs 2.0) and ratings volume (27 vs 3). Arpeggist's advantage is price ($2.99 vs $14.99) and iOS requirement (7.0 vs 13.0). On ads, in-app purchases and monetization model there is nothing between them.
