Since its first release in 2005, FabFilter Twin has been famous for its filter quality and oscillator sound. FabFilter Twin 3 expands and improves on its predecessors in every area, including a complete redesign of the GUI and workflow, more and better oscillators and filters, a radically powered-up modulation system, an all-new FX section, and much more. Sonically versatile, supremely intuitive, and spectacularly ‘analog’, Twin 3 is a dream instrument for creating synth sounds of all kinds, from basses, leads, and pads to plucks, drums, effects, and beyond. The Twin 3 app lets you play via the on-screen keyboard or a MIDI keyboard connected to your iPad. To use Twin 3 as a plug-in, you need an AUv3-compatible host app like Auria, AUM or Cubasis. Twin 3 will appear in the list of Audio Unit extensions for instrument plug-ins in the host app. Key features: - Virtual analog synth featuring four flexible oscillators, four filters, six FX modules, and a vast modulation system with a wealth of flexible source signal generators, drag and drop source/target routing, and no limit to the number of modulation assignments that can be made - Fully redesigned, greatly simplified interface with easier workflow - Completely overhauled modulation system with redesigned modulation sources, and floating slot and FX panels - All-new FX section, housing Reverb, Delay, Chorus, Phaser, Drive, and Compressor modules - MPE support for expressive, per-note modulation - Arpeggiator with Groove/Legato controls, note order, latch options, and more - Full-featured preset browser, with tags, favorites, and search and filter functions, and new factory preset library - Per Oscillator polyphony mode: each incoming note triggers a different oscillator - Bell, Shelf, and Notch vintage-style EQ filter shapes - 6dB/octave filter slope option - Modulatable filter Cutoff/Peak Offset knobs knobs, for adjusting all filters at once - High Quality mode — 4x oversampling - Transient mode turns Envelope Followers into transient detectors - Curve adjustment handles for EG Attack, Decay, and Release stages - Slider mode (vertical-only operation) and Range setting (toggles between bipolar and unipolar behavior) for XY controllers - Hide all modulation sources except for XY controllers and Sliders at a click - Native sustain pedal support - Even better oscillator and filter sound quality, with analog-modelled drift - Maximum number of voices doubled from 32 to 64 - Lower minimum Envelope Generator Attack, Decay, and Release times - Maximum number of XY controllers/Sliders increased to six - Envelope Generator Threshold, XLFO Balance, and Frequency Offset made available as modulation targets - Modulation sources can be renamed - Maximum number of modulation slots increased to 100 - Legato mode for MIDI-triggered XLFO - Range options added to MIDI Sources: Negative (-1 to 0), Centered (-1 to 1), and Positive (0 to 1) - Carefully designed and curated factory presets, plus the ability to save your own presets - Undo/redo and A/B comparison "FabFilter Twin is one of the best virtual analogues we've heard so far, and at this price point it's well worth the investment!" — Computer Music "Once I found FabFilter Twin, I immediately noticed how great it works and how amazing it sounds!" — George Morel

A new and unique Arpeggiator by BLEASS & Canblaster. Use it as a MIDI FX to control any synth or as an AUv3 Instrument thanks to its built-in FM Synth! BLEASS Arpeggiator takes the inspirationally melodic power of a classic synth arpeggiator and supercharges it with modern features demanded by today’s musicians. Developed in collaboration with top French producer Canblaster, BLEASS Arpeggiator’s capabilities extend far beyond the clichéd up-and-down monophonic patterns of an old-school synth arpeggiator, with polyrhythms, polyphony, and a large collection of highly configurable arpeggio patterns built in. The focus of BLEASS Arpeggiator is creativity and experimentation. The plugin’s hands-on user interface is as intuitive and spontaneous to use as a classic subtractive synth, so varying and adapting arpeggios on-the-fly is an easy, fun and organic experience. The plugin recognises incoming performance controllers, and includes a pair of XY pads, a pair of advanced LFOs and BLEASS’ signature Motion Sequencer. These can modulate the arpeggiator’s parameters, unlocking a deep level of creativity that is simply not available from modern step-sequencer-style arpeggiators. BLEASS Arpeggiator also offers a built-in sound generator. This is a cut-down yet great-sounding FM synth that’s perfect for creating bright, sweet and punchy sounds that can work well with an arpeggio line. You can of course use BLEASS Arpeggiator with any other synth too, with each instance of the plugin creating its own MIDI source that can be routed to any instrument within your project. More information, technical specifications and tutorials available on https://www.bleass.com/arpeggiator BLEASS Arpeggiator is available as an AUv3 plugin or standalone App. BLEASS Arpeggiator is also available for Windows, and macOS.
