The occurring problem::
Midi on Windows Vista and Windows 7
Vista and W7 are often a 64-bit version and Midi seems to not want to work with that before.
Some importers still write good drivers for a Midi device on earlier 64bit computers, but without updates this is often an extra challenge.
Here are a few testimonials from fellow Midi users..
The experiences of others:
ESI MidiMate eX USB 2.0 (1 midi-in and 1 midi-out) is a USB-Midi interface
This is already for sale around 25 euros.
Below you will find a number of information sources:
The latest updates of Windows 7 are quite good. Everything works "Plug and Play" and there are few problems.
Windows 10 works very well. Of course there are still challenges, but most of the time you can find the right drivers.
