Elektron's Octatrack is an elegant sampler and sequencer in one, which basically means it provides you with a full-blown hardware production system.
This sample player is the fourth member of the Volca family. You can import samples via an iOS app (for iPhone and iPad), adjust the eleven synthesis parameters and get creative with the step sequencer.
This portable sampler provides you with CD-quality recordings and saves them on a SD card. All samples, both recorded and uploaded, can be edited and subsequently triggered by means of the 16 backlit pads.
