And now for the performa 6116. I have connected midiman macman midi interface to the computer with a serial adb cable. Then i connected a 5-pin midi cable. The one edge to the midiman at midi out port and the other edge to roland mt-32 at midi in port. The midiman macman has only the power light turned on and not the other lights( midi in and out). I have copied the midi manager to extension folder but when i try to run some sierra games that support roland a message comes out that 'cannot find any midi clients or midi ports' What should i do?
