Vesuvius Sampler is a 10-part groovebox for the iPad that emulates the Korg volca sample from the Korg Volca series. Developed by Finegear using Korg’s open source SYRO SDK, Vesuvius is designed to help users select, prepare, sequence and upload their samples and pattern sets for their Korg volca sample.

As an emulation of the Volca Sample, it fully reproduces the features and interface of the original hardware unit. It brings to the iPad environment the intuitive sequencer and sampler and the same array of sample manipulations enhanced with an analog isolator and an assignable reverb effect.

More than just an emulation, Vesuvius also features sample importing, MIDI sync, MIDI mapping (and learning) as well as audio session recording in order to make it as usable as possible.

There is also a sample edit view which features browsing and import options (internal library, iTunes shared folder) as well as direct sample editing, further enabling you to load and edit any of your samples wherever they are!

To load samples and patterns on Volca hardware units, Vesuvius integrates Korg’s SYRO SDK and offers a complete solution that streamlines your workflow.

You can use Vesuvius as a standalone groovebox or just to prepare your sample sets and patterns for your Volca Sample. It is also a great app to discover the world of sampling and sample mangling.

Hopefully this continues developing

In it’s current state, this crashes once in awhile. This is a great idea though. Hopefully a pattern editor will be added soon!
