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.

ToneBoosters Reverb is a studio-quality, professional reverberation AUv3 plug-in with an unrivalled workflow, unlimited creative use and a gorgeous, functional user interface. With its close to a hundred adjustable parameters, the integrated LFO for parameter modulation, integrated compression and gating, and its shimmer reverb module it is by far the most flexible and configurable reverb on iOS. The ToneBoosters Reverb app captures the microphone input and processes the signals in real time. To use it as a plug-in, use an AUv3-compatible host app such as Steinberg Cubasis, Apple Garageband, Audio Evolution Mobile Studio, Auria, AUM, or others. ToneBoosters Reverb will appear in the list of Audio Unit extensions for effect plug-ins. Key features: - Studio-grade reverberation including early reflections - The same professional sound as the acclaimed desktop version - Full control over room size, width, density, depth, mass - Integrated spectrum analyser showing direct and reverb simultaneously - Integrated equalizer to shape the reverberation character - Ability to modify reverberation time across frequency - Compression, ducking and gating for dynamic reverberation effects - Flexible, beat-synced LFO that can modulate almost everything! - Dual pitch-shift shimmer module for out-of-this-world reverberation - Reverb freeze option - Random parameter option to change the core reverb sound on the spot - Eco mode for lower CPU load on complex projects - Program manager with shared programs between stand-alone, IAA and AUv3 instances - Undo/redo, and A/B comparison - Color themes for the user interface - Max screen support in Garageband - Optimised for iPad and compatible with iPhone and iPod Touch Compatibility Please note that given the large flexibility and number of parameters that can be modified with this reverb, the use of an Apple pencil or stylus is highly recommended for smaller devices such as iPhone and iPod touch. What you should know: - Licenses acquired for this platform are not compatible with other platforms. - Audio Unit (AUv3) extensions require an iPad mini 2, iPad 4 or later models.
