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.

- Perfect iCloud integration* -
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. Even more this 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 setting

- 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.

- Versilian Studio Sample Library ( VCSL/VSCO ) for free download

Plugin used to crash a bit a long time ago...

This has always been a decent app, and nowadays it might even be very good. I’ll definitely update this review as I explore the updates that have passed since I stopped using it because of an issue I used to have sampling as AUV3 fx. It would crash after sampling/configuring more than 5-6 samples/layers. I do feel like this has been addressed but since I’m only going about this from what I remember from reading the update notes of the updates I missed (which I read as such updates came out but never actually explored since I’ve been kind of busy ever since).

If this has been fixed I will come back for a 5 star update, as otherwise this app was pretty good even with the issues it had.

Finally an actual iPad sampler whose functions are not buried beneath trendy bells and whistles. I had no problem air-dropping in samples from my laptop. So easy! I was able to quickly build a multisample instrument with over 20 samples, each with their own unique settings. So far I've worked mainly on the "zone" level but am looking forward to exploring the other editing levels. I am using it solely as a stand alone app so I can't address any plugin issues. I also don't quite understand the "scope" situation; specifically why the default is having it off for each zone. I hope the future manual will explain the whole "scope" thing more thoroughly.

On the top of my wish list is deeper real time midi control over editing functions. Specifically I'd love to be able to control sample start and loop points via midi cc. That would be excellent! But over all, Virsyn continues to amaze.

Great sampler

Great sampler, especially once you get to know it better, some of the features may not be that intuitive but it has some great features and the new Auto sampler is something I’ve always wanted in an IOS, i love being able to sample patches automatically from non AUV3 apps. The 2 features that I would love to see are time stretching so if I auto sample something with effect or modulation the sample doesn’t spreed up as I play higher note, and a feature that auto chops samples across all the keys automatically. I have ReSlice that doesn’t that but would love to have that feature in AudioLayer because of the much deeper ways you can affect layers and key groups independently. Besides that I think this is the best IPad sampler.
