Final answer:
It is true that S6000 user presets can be backed up using MIDI. This involves the use of System Exclusive (SysEx) messages, part of the MIDI protocol, to transfer the preset data.
Step-by-step explanation:
The statement that the S6000 user presets can be backed up using MIDI is true. The Akai S6000 is a professional sampler that is part of Akai's legendary S series of samplers, designed for high-quality sound manipulation and production. User presets, which include settings, samples, and other configurations, can indeed be saved and later restored via MIDI, which stands for Musical Instrument Digital Interface. This process typically involves sending System Exclusive (SysEx) messages, which are a type of MIDI message utilized to transfer preset data between the sampler and a computer or another MIDI device.
