If you are not using the connection between the P-250 and your computer, you must disconnect the cable from the [TO HOST] or [USB] connector. If the cable is connected, the P250 may not function properly. The connectors that can be used depend on the setting of the [HOST SELECT] switch.
[HOST SELECT] Switch Setting
The P-250 will begin transmission soon after the USB connection is made.
When using a USB cable to connect the P-250 to your computer, make the connection directly without passing through a USB hub.
Usable connectors MIDI [IN], [OUT], [THRU] connectors [TO HOST] [USB]

MIDI PC-2, Mac USB

Depending on the state of your computer, the operations of the P-250 may become unstable. Do not use your computer in a way that causes it to become unstable.
Different computers require different connections, as follows.
If you turn the power of the P-250 on or off, or connect or disconnect the USB cable in the following states, problems will occur in the computer system, possibly causing it to freeze (hang up), or causing the P-250 to stop functioning: While installing the driver While starting or shutting down the operating system While the computer is in Save Energy (Sleep) mode While a MIDI application program is starting up.
Setting the [HOST SELECT] switch
Set the [HOST SELECT] switch according to the type of connected computer: Macintosh: Mac (data transfer rate: 31,250bps, 1MHz clock) Windows: PC-2 (data transfer rate: 38,400bps)
Performing the following actions may cause your computer to hang up or cause the P-250 to stop functioning: Turning the power on or off, or connecting or disconnecting the cable too often Shifting to power-conservation (sleep) mode while MIDI data is being transferred, or returning from sleep mode Disconnecting or connecting the cable while the P-250 is on Turning the power to the P-250 on or off, starting up your computer, or installing the driver while a large amount of data is being transferred

Local On/Off when a computer is connected
If the P-250 is connected to a computer, keyboard performance data is generally sent to the computer, then returned from the computer to trigger the P-250 internal tone generator. If the Local Switch is set to on, the P-250 will play the song in unison, since the internal tone generator is receiving performance data from both the keyboard and the computer. Use the following setting as a guideline; specic instructions may differ depending on your computer and the software used.
