I have connected my roland mt-32 via macman midiman interface on my performa 6116 and i have copied the necessary files to the extensions folder. When i run sierra games (like King's Quest, Freddy Pharkas etc.) using the roland mt32 driver it seems that it works. The lcd screen of roland is showing various messages while the game is running. The problem is that i do not hear any sound. I did something like that: I bought a cable almost like this http://www.proaudiosuppliers.com/hosa-cmp-159.html. The difference is that all the edges are 3,5mm so i also bought two adaptor converters from 1/4" to 1/8". I connected these adaptors in the two jacks (L & R) of roland mt-32,then i connected the two edges of the 3,5mm cable in the adaptors and the other edge (the third) i connected it to the 'mic' jack of my mac. I don't hear a thing. What do i have to do? The roland all the time is showing midi messages (various titles of the music that plays) while the games are running. It seems that it is working.
