・Transform your iPhone and iPad into a portable DJ set designed for the art of scratching・ We’re excited to bring you an app that redefines the possibilities of dj scratching with a single hand-held device, ready to be used on the go, anywhere you want. Skratch it! transforms your iOS device into mobile turntable / mixer / loop player combo, allowing you to instantly experience limitless possibilities right at your fingertips. ・Seamless scratch experience・ Thanks to the implementation of a highly responsive virtual deck and a semi-automated mixer’s crossfader, it is possible to achieve both precision and finesse of performance even for beginners. The mixer section offers eight, carefully selected, crossfader movement patterns that are automatically synced with the tempo of background music playback. These can be easily combined together by the swipe gestures, allowing to create endless combinations of the scratching sounds. The app comes with a selection of six different sound sets, containing most of the all-time classic samples together with some fresh beeps, squelches and rough noises! Eager to cut and bend your own sounds? Importing custom samples is also possible. ・Packed with useful features・ - Dope selection of background music tracks (80 - 140 bpm) - 6 pads for switching between different scratching sounds sets - Mixer unit with pattern-driven tempo-synced and manual modes of the crossfader - Responsive, large, virtual deck with triggers for performing “stab” and “faderless” tricks - Possibility to cue and trigger selected part of the record - 4 different DSP effects - Live recording to WAV (record your performance with or without the background music) - Importing of custom samples (44.1khz, stereo, 16-bit WAV files) - Tap tempo button for fast tweaking of the playback speed - Audio routing (audio output from the app can be routed to another app that supports IAA) - Built-in tutorial - Hours of fun and engaging experience!

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.
