Depends what kind of MIDI cables and joysticks you already have.
I have to assume your MIDI adapter does not have joystick pass-through and you are trying to connect MIDI adapter to other port and single joystick to another? This won't work - you'd have to connect the MIDI adapter to primary joystick port (that can be used to connect 4-axix/4-button/special joysticks) because the secondary joystick connector does not have MIDI pins and with MIDI adapter on primary you can only connect a standard 2-axis/2-button joystick for player 2, and even then it is required not to use the pin 8 for power. If you manage to find a joystick that works on secondary port, even then the primary joystick for player 1 must be a standard 2-axis/2-button as well or the two joysticks will conflict with each other.
If your MIDI adaptor has a pass-through connection for joysticks, it may or may not remove the MIDI pins from the joystick and put power pins there instead, so there is a chance that any joystick can be used with it. Either a single special joystick, or by using the Y cable you posted, two standard 2-axis/2-button joysticks.
So from the looks of it, you'd have better luck with MIDI + joysticks if you bought a MIDI adaptor that has joystick pass-through connection. These usually don't come with Y cable feature built-in so if you want to connect more than one joystick then you need an Y cable as well.
