Connecting External Equipment
Connecting to a Computer or Mobile Device
You can transmit and receive audio and MIDI data by connecting a USB cable from your computer or mobile device
(smartphone or tablet) to the SP-404MKⅡ.
You donʼt need to install a device driver on your computer or other device to do this (the SP-404MKⅡ supports USB
Audio Device Class 2.0 specs).
Connecting the SP-404MKⅡ to your computer or mobile device lets you transmit/receive audio output and MIDI
data to and from your computer or mobile device and the SP-404MKⅡ.
Note that data cannot be directly transmitted/received between the SP-404MKⅡ and your computer or mobile
device if youʼre connecting through a USB hub.
Do not use a USB cable that is designed only for charging a device. Charge-only cables cannot transmit data.
We cannot guarantee the correct functionality of all apps.
Android devices are not guaranteed to work with this unit.
