Ribbons is an extraordinarily fun and expressive musical instrument. Inspired by early electronic instruments such as the Ondes Martenot and the Theremin, Ribbons (formerly "Ondes") emulates the fluid playing style of those classic instruments with an interface and synthesis engine firmly grounded in the present day. Whether you’re gliding through melodies & chord changes or creating dense polyphonic sci-fi soundscapes, Ribbons is an instrument unlike any you’ve played before. • 2014 Best iOS Instrument - Sonic Joy Awards • • 9.0 / 10 - Apptronica Magazine Review • Recommended for use with headphones or external speakers. Ribbons is made by Olympia Noise Co., developer of Patterning and Chordion. •••• Expressive Playing Surface •••• Slide freely between notes, Ribbons doesn’t limit you to the keys on a keyboard. Use 3D Touch on supported devices to control synthesis parameters. Adjustable note snapping for ultimate flexibility in playing style and ease of use. Use the hold function to sustain notes while you take an epic solo on top. Vertical movement can be mapped to volume and synthesizer parameters, adding dynamic possibilities to your music. More polyphony than you have fingers! Adjustable keyboard range and size. Guidelines help you play in key. Choose from common scale types in any key or create your own. Alternate tuning systems let you explore the world of microtonal sound! •••• Unique Synthesis Engine •••• Morphing wavetable oscillator with five wavetable sets. Swarm oscillators! Two extra oscillators can be detuned and lag behind to create new textures. Wavetable modulation sources include Y-Axis, sine wave, noise, circle, and ADSR envelope. Resonant low pass filter. Filter modulation sources include ADSR envelope, sine wave, and Y-axis. Amplifier section with master volume, Y-axis control, and ADSR envelope. Y-axis can be mapped to control the rate and depth of wavetable and filter LFOs. •••• Effects •••• Large selection of reverb types with adjustable amount. Delay effect adjustable level, feedback, time and filter. •••• MIDI •••• Use Ribbons as a MIDI controller to control your favorite software and hardware synths. Now supports MIDI Polyphonic Expression (MPE) output or use "classic mode" to manually managed MIDI ports. Map each touch to a unique MIDI Port/ Channel for polyphonic pitch bend. Because of Ribbons' unique pitch bend capabilities, it isn’t like other controllers, so make sure to read the instructions to learn about how to get the best results. •••• Inter-App Audio •••• Record directly to Garageband and other audio apps on your iPad using Inter-App Audio or Audiobus. Built-in Inter-App Audio transport allows you to control a host app’s play, record, and rewind buttons. Supports Audiobus State Saving. •••• Beautiful Design •••• Visualization of synthesis parameters makes for fun and intuitive editing of parameters. Clutter free screen lets you focus on making music. •••• Built-in Manual makes it easy to dig in and learn about Ribbons’ features.

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.
