Why Can't I Hear My Dx7 On My Sequencers?, DX7: MIDI and Audio SETUP for Sequencers Options

Hello,

I've got the following equipments:
- an imac with Pro Tools Free and Logic AUdio running under OS 9.2.2,
-a Yamaha DX7,
- a Midisport UNO 1*1 Midi Interface
- OMS 2.3.8

The Midi IN/OUT are OK but the issue is that I can't hear the DX7 on the Mac eventhought I connected its audio output to the audio input of the Mac?

The audio output of the DX7 works perfectly when I connect it to my stereo so the problem must be related to the configuration of the sequencers (which is not so well explained in the manuals...).

Thank in advance for your help!

Bye,

John

Ok, now I know I'm sounding redundant but... While you were looking in your sound control panel, are you sure that the box next to the "Play sound through output device" is checked.

If it is, does the jack going into your computer look exactly like a headphone jack? Are you positive that the cable is not defective?

If all of the above is done, and you still can't hear your sound on your computer, then there is the posibility that the input jack on the computer itself is defective. In that case you will need an external sound card. I'd sugest a firewire audio interface, but if money is an issue, go for a USB one. Be aware that the USB audio interface will have more latancy than the firewire one. I'm not sure if you can use a extagy USB esternal sound card will work on a mac or not, but you might look into it. It is definatly not the best, but it should do.

Now then onto the question of how I procede exactly.....
I have every thing running into a Behringer 20 channel mixer. The sound out of the mixer into the iMac sound input. I'm using a midiman2x2 midi USB interface for sequencing. As far as listining to what I'm doing, I have one of the head phone jacks running to a stereo, the other has head phones connected to it. So I'm not using the speakers of the mac, but could. Some times I take the sound running to the stereo, and run it back into the mixer for mastering. In this case I uncheck the play through device command to keep from having a loop which causes really bad feedback!
