Best Friend for K.O. II
Best Friend extends supported Teenage Engineering EP samplers with editing, backup, MIDI and export controls.
Choose after confirming the exact sampler and cable requirements.
Scene views, sample editing and hardware stem capture provide a larger working interface for the physical instrument.
Keep in mind: Core operation requires EP-133, EP-40 or EP-1320 hardware; limited backup preparation while disconnected is not standalone sampler operation.
