System 7.5 sound in options for Roland MT32

Hello,

i have a roland MT32 sound device for the sierra on line games which was connected to my Macintosh Performa 6116 (Mac OS 7.6, Mac OS 8,1, Mac OS 8.6). In order to hear the sound i have to go to sound panel, sound in options, choose the mic option and then the listen box. My roland MT32 is now connected to my Macintosh LC475 with system 7.5. The device is connected correctly (exactly the same connection like macintosh performa 6116), the midi messages work great but i cannot hear the sound because at the 'sound in' options there is nothing to choose (av connector, mic, cd). Why there are not these options at the sound in (built in) panel? What can i do? As i wrote above at my mac performa when i wanted to hear sound from the cd (for instance a game that has music from cd or a music cd) i was checking the cd option. When i wanted to hear sound from the roland mt32 for some sierra on line games that support them, i was checking the 'mic" option and the 'listen' box. Now these options do not exist at all.

Regards

Dimitris

Hi Dimitris1980,

Is there some drivers which comes with your sound device ? If so, I suppose they must be installed in your LC 475 to work properly with it... If not, may be u need to upgrade your machine to 7.6 if there is a compatibility issue.

The sierra on line games have the drivers inside their games folder and you can play them also at system 6. Everything is ok, the roland plays ok, midi msg show up on the screen but no sound. At the macintosh performa i had to go to "sound in" panel, choose the mic option (one cable is connected to two jacks of the roland and the other edge to microphone port of the computer) and check the "listen" box. Then you hear sound. If the "sound in" panel is at "av connector" or "cd" you cannot hear the sound. But at system 7.5 when i go to "sound in" panel there are not any of these options (av connector, mic, cd).

Shouldn't be a "mic" option at the sound in panel? I connected the apple microphone and i am trying to record an "alert" sound but nothing.

It could be the motherboard needs to be re-capped.

Did you install 7.5.5 from scratch on the 475? Could also be some drivers are missing.

I installed a 4.5gb hard drive in my macintosh performa 6116 in order to make two partitions and install System 7.5 for the LC475 and Mac OS 8.1 in order to be able (due to format) to copy lots of games and programs to system 7.5 folder. Then i took the hard drive and placed it inside the LC475. I did all this process because i do not have a cd rom drive for the LC475.

Also the 6116 is a PPC the 475 is not. So I'm not surprised you are having issues.
If the floppies are an issue. You can delete the 7.5 System folder and use the single file 7.5.3 installer and the single file 7.5.5 updater.

7.5.0? 7.5.3? 7.5.5?
I'm not sure that works.
I would download and build a set of 7.5.0 floppies. Download #11.

Also download the 7.5.3 and 7.5.5 sets which include a single file "network" installer.

If you still have issues I think the motherboard might need to be recapped.

I would also point out that Quicktime Musical Instruments is based on the Roland Sound Canvas GM (General Midi) sample set.

I did the installation using a cd from macintosh garden with lots of system/mac os inside (apple legacy recover cd i think) but i did it with my performa 6116 because i do not have a cd rom drive for my LC475. I believe that you are right, maybe this is the problem. I will try when i find time to do the installation directly to the LC using floppies or maybe to find an external scsi cd rom drive.
