AudioLayer satisfies the most sought after gap for contemporary music production on iOS devices. AudioLayer is a full featured open standard audio multi-sampler pushing the boundaries beyond what has been available even in the desktop music production worlds. And all this integrated in all relevant iOS production environments especially the emerging AUv3 AudioUnit standard. - SSE - Streaming Sample Engine - The ultra efficient Streaming Sample Engine SSE is capable of playing hundreds of voices of big multi-sampled instruments even in strictly resource limited applications like using multiple instances of AudioLayer in AudioUnit host environments. Innovative features like Sub Sample Looping for perfect loops even in the audible range extend the range of applications even further. - Multiple storage options - The consequent usage of the open file structure of the Files app makes organising even large sample libraries a breeze. Sample recordings and Instrument designs made with AudioLayer are seamlessly available across all your devices and desktop using either iCloud storage or external SSD. The iCloud option opens up new forms of collaborations with musicians all around the world to share your creations and work together. - Multi Scope Editing - To support the creation of complex multi-sampled instruments AudioLayer allows you to use a hierarchical structure of Layers and Zones each with it’s own sound manipulation parameters. A unique element of AudioLayer is the possibility to decide for each Zone at which Scope level your editing apply: For the all Zones in the Instrument, for the Layer only or individually for this Zone only. This opens a whole new world of creative options for sound mangling. For sound manipulation you can use a full set of Filters, Envelopes and LFOs to shape the pitch, timbre and level of the sound of each Zone. SIS - Seamless Instrument Switching The unique architecture of the Streaming Sample Engine allows for instant loading of even complex instruments and makes this switching from one Instrument to the next without cutting off the sound! And this includes of course also different effect settings - Easy Design Workflow - The built in audio sample recorder let you create Instruments on the fly in seconds. The Music Effect AudioUnit / Audiobus effect plugin of AudioLayer let you record multi-samples semi automatically directly inside your preferred host and instantly create an Instrument with the help of several Auto mapping options available. This includes file name based mapping of key ranges and velocities and automatic pitch detection. For the creatives we’ve also integrated a special “Single Cycle Waveform” detector making the use of this special files a breeze. - Auto Sampler feature for easy creation of Sample Instruments from hardware synthesiser. - Versilian Studio Sample Library ( VCSL/VSCO ) with excellent strings and orchestra samples for free download - Exchange libraries with XinematiX App Integration • Stand-alone App • Sample import for EXS24 and SFZ Format • AUv3 AudioUnit Instrument and Music Effect • Inter App Audio • Audiobus 3 Input/Effect with state saving support. • Audio recorder with share function. • Ableton Link compatible.
