To host

A To-Host interface ( English to host "for host") is a serial interface between computer and peripheral device . In practice, the ambiguous but common term does not mean a separate "interface", but a mini-DIN socket with a switch for various host systems - Mac, PC1, PC2, MIDI. With a suitable cable you can connect the electronic musical instrument to the serial port (e.g. for the printer) of various computer models.

Since the serial interfaces were replaced by the USB (Universal Serial Bus) at the turn of the millennium, manufacturers have also referred to this connection as a USB to host connection; a switch was then no longer necessary.

The connection enables data from e.g. B. to exchange electronic pianos with various computer models, while the also widespread MIDI connection (standard DIN socket) on the computer also required a separate MIDI card. The advantage of the serial interfaces lies in the higher transmission rates and maximum cable lengths.
