• Exospheric stereo reverb with ultra low latency pitch shifting • Amazingly lush, dreamy and beautiful • Shimmer kind effect, harmonizer • Unique feedback processor and fine tuning of the All-Pass delays • High-pass filter and stereo width input controls, separate Dry/Wet outputs • Sidechain input to duck the reverb • Multiple outputs, extra output bus to route the feedback signal to your own fxs • Advanced Responsive Design, portrait and landscape views • iOS Audio Unit V3 - Universal (iPad/iPhone) Designed for ethereal lush sound textures and dreamy space reflection, FAC Alteza is the perfect solution to bring your instruments to heaven in no time. Thanks to a powerful feedback section containing, inter alia, two pitch shifters, the unit is able to deliver the very typical "Shimmer" sound kind effect very much prized by musicians that are making ambient music, or any kind of music that needs to be carried by a fabulous angelic evolving choir section. FAC Alteza is definitely not "another shimmer reverb..." effect because it comes with additional parameters that make it very versatile. A particular attention to each part of the signal path was necessary to reach this level of high-end quality. Here some features that make FAC Alteza an outstanding unit: • the input signal is not monoized by default, a knob allows to control the width of the input stereo image before reaching the reverb • the topology of the effect, based upon a series of All-Pass delays, allows to control the intrasec characteristics of the reverberation • the number of All-Pass delays per stage and the echo density are alterable in the main section and in the feedback section • two ultra low latency pitch shifters deliver progressive pitch-shifting of the reverberation tail or the input signal • the feedback section contains a blend knob to control how much of the original signal is mixed with the feedback reverb • the wet signal can be ducked by an external signal provided by the host - AuV3 and Standalone App - To use the sidechain and/or to output the additional feedback signal, you need a host able to provide to the AuV3 an input bus and an additional output bus.

DigiStix 2 is an AUv3 compatible drum machine and sampler plugin for your favourite DAW. This new version of DigiStix brings some distinct advantages over its predecessor, most notably the ability to host up to 64 samples per drumkit with 5 layers per pad. The interface has been drastically redesigned for iPad to make better use of full screen mode, allowing a popular MPC style 4x4 pad layout with 4 banks of samples. Digistix 2 also allows greater control over the multi-sample layers, with the ability to individually control the volume levels and pitch of layers as well as global pitch and tune settings all from the new sample window. Previously, each pad had effect sends for the internal reverb and delay effects, but this can now be routed to external busses 9 and 10 for processing using external effects. The controller editing is now build into the main display and can be edited in place without the need to scroll the interface. It also now supports extra effect controllers. A new context aware control window allows you to quickly change pad settings without the need for popup windows. DigiStix 2 now supports GM and original DS drum kit layouts, and includes a sophisticated multi-layer Auto Sampler, capable of recording new GM compatible drumkits automatically from your hardware. It is 100% backward compatible with the original app, and can be used as a drop-in replacement. Drag and drop support now allows you to directly drop samples on specific layers, as well as preview and edit them directly. You can create new kits by simply combining banks from existing kits into one mega kit, or use our non destructive referencing to include sounds from other kits. The randomize feature has been enhanced so you can randomize individual instruments or within specific banks. The new continuous MIDI learn mode makes custom mapping a breeze. Patterns can also be exported as MIDI stems for use in other packages including a direct import to Helium clips. You can also export patterns as audio in the latest version. The auto sample feature allows automated recording of GM compatible kits directly from hardware drum machines. The slice editor can also be used for MPC style slicing of audio clips. Features: • 64 Assignable Pads (4 banks of 16 pads). • Advanced Randomize Pattern feature. • Internal & external effect routing. • Mix and match different kits with drum references. • Up to 64 beats per pattern. • Songs up to 255 patterns in length. • Reverse Mode, Triplets and Accents. • Supports Mute Groups. • Multi-layer and Round Robin modes. • DS and GM MIDI Mapping. • 64 channel Mixer. • 8 band EQ. • Randomize Feature. • Sophisticated Auto Sampler • Export loops to audio and MIDI formats. • Looping Mode with Time Stretching. • Build in Delay, Reverb, Overdrive, Bit Crunch and LP/HP Filters. • Paramter Automation from your DAW. • Local and Remove MIDI Sync. • Built in Sampler. • Multi-bus/outputs when using AUM • Multiple Import options. • Melodic Remapping. • MIDI Mapping. • Real time and Step pattern recording. • iTunes and Filer importing of samples. • Files App Drag & Drop Support • Sample Slicer
