Dear Customer ! Here is some important information you need to know to install Cubase properly. Before you start you have to decide whether you want to use the MIDI drivers which come with Windows 3.1 and/or from the vendor of your MIDI interface or alternatively the drivers which come with Cubase. 1) Using Cubase with MME drivers In this case you have to run the MIDI Setup program which comes with Cubase and activate Multimedia MIDI. Please disable all other interfaces. You should then use the Control Panel, found in the Main Group, for setting up drivers which are a part of Windows. Here you have to install the MIDI driver according to the instructions which come with your MIDI interface. 2) Using Cubase with it own drivers In this case you should run the MIDI setup and activate the driver for your interface. If you select the interface option you will see some optional fields which have to be filled according to the instructions of your MIDI interface. Please make sure that all other drivers are disabled. After quitting the program with OK you should start the Window`s Control Panel for setting up drivers and make sure that there is no driver installed which talks to the same interface as Cubase. This can lead to strange behaviour and you should therefore remove the relevant driver. Cubase needs the Windows Timer driver in order to run. Please make sure that the Timer driver is installed in Windows. It can be found in the driver Control Panel in Windows. Additional Information: Commonly in PC compatible computers certain IRQ and Base Addresses may be used internally for the Monitor and Printer Port. If you have a situation where the Set Up program and the physical setting on the card match but nothing works, try another IRQ and Base Address pair. If you get the situation where Cubase can transmit data out of your interface but fails to see any MIDI input, you have almost certainly got the Base Address correct but the IRQ wrong.
