Midi Out - Samson Graphite 25 Owner's Manual

MIDI OUT

In addition to USB, the Graphite 25 features a MIDI OUT jack. The USB communication proto-
col supports four virtual USB In ports and four virtual USB Out ports. MIDI messages from the
keyboard set to Port 1–4 are transmitted via the USB Out. Messages sent to Port 1 and Port 2 are
also transmitted through the MIDI Out terminal if the Local switch is set to On. This is the default
setting. Messages sent to Port 3 and Port 4 will not be transmitted through the MIDI Out terminal.
Messages received from external device or computer software through the USB In Port A will be
transferred to the MIDI Out terminal. The USB Out Port 5 and In Port B are used for the remote
control only.
The diagram below shows the configuration of the MIDI Chain.
