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

Do you virtually route the DX7 audio to the audio track on OMS or do you mean that I just have to create an audio track on which I can record the DX7 audio?

That. What you said. Yes, create an audio track, and make its source the audio input of your iMac--which is what the audio output of your DX-7 is *supposed* to be coming in through. Then put that track in "Record" mode and hit the darn Record button. Whatever is on the MIDI track (that is assigned to go out to the DX-7 on the correct channel) should then cause the DX-7 to commence music-making, the audio output of which should then start recording into the audio track you have in "Record" mode (with the iMac audio input as source).

Stop it when you've had all you can take.

Could you please tell me how to turn off the playback of the Midi track?

One word: Mute.

So if I add effects on the audio track, can they be directly affected to the midi track too (and vice-versa)?

One word: No.

They are two completely different classifications of data. MIDI information is essentially triggering information for modules that have an internal way of generating sounds, telling them what sounds to start generating, for how long, etc. (There is other information MIDI can carry, but that's another course.) MIDI contains no sound, just instructions.

Audio files are digital recordings of sound.

They are worlds apart, and the software audio effects you can add to a track (VST, etc.) are for affecting those digital recordings of sound (or live audio coming in), not MIDI.

When you are satisfied with the results, which track do you usually keep, midi or audio?

Depends on what your application is. Some people don't record audio of their MIDI tracks at all, like with a multi-timbral synth playing different sounds on different channels, or several different MIDI sound devices playing together. They just record strictly unMIDIable stuff (vocals, guitar, sackbutt, daltry, whatever they choose), setting the mixes and effects they want on their synths/samplers that are playing back from the MIDI tracks, and then only record the output of the MIDI devices in the final mix, mixing it with the audio tracks then. (Same might go for a software synth/sampler in the session.)

I generally record everything that's MIDIed down to audio (once I'm happy with the MIDI stuff), then delete all the MIDI tracks and save AS a new session number. If I want to change something later, I can always go back to a version of the session that had the MIDI in it and pull a MIDI track in to further edit: lather, rinse, repeat.
