Music Quest (Opcode) 8PortSE

The 8PortSE is a MIDI interface designed for Windows that uses parallel port for communication with the computer.  It is a versatile MIDI Patchbay/SMPTE sync device that supports 8 MIDI Ports (both In and Out).

It is renowned for low jitter and low latency and through the extraordinary work of developers such as Earth Vega Connection, drivers are available that work for all versions of windows up to Windows 10.  Not bad for a device that was originally designed for DOS and Windows 3.1.

Below are all drivers I have been able to find for this device, going back to the original floppy that shipped with the unit, through Windows NT, XP, 7 and 10, as well as the original manual.

The latest driver is the Windows 7 driver created by Earth Vega Connection and is confirmed to work in Windows 7, 8 and 10 with driver signing enforcement disabled. While we looked at recertifying this driver, it's not feasible for me to do so, so I'm providing the original with default user registration. A thread discussing this is here

This has not been tested by us for Windows 11, but if you have success, please Contact Us and we'll update the description here.

We thank Earth Vega Connection for permission to republish their driver and make it available to the public. 

All other drivers and manuals are provided free of charge
