The External Instrument's audio is coming up on another channel?

OK,

I have a MOTU 128 MIDI interface and MOTU 828 mk3 audio interface.

I have checked numerous times that my 3 keyboards are routed correctly.

...all the MIDI ins/outs are correct and the keyboards audio routed to the mk3 is correct.


Now, in Logic I want to use each keyboard as an external instrument (EI).

When I create a new (EI) lets says my Alesis micron, its input is 1-2.

Next (EI), Juno-D. Its channel is 3-4.

If I play something and make a little loop on the Alesis' channel I can hear what I did...so thats good.

But if I mute that track (the Alesis), I still can hear what I just recorded.

Well,..the audio is coming in on the Juno-d's channel 3-4.


Its the same for when I create my next (EI). The motif. Its channel is 5-6.

If I play something from the Juno-d, record and loop. I can hear it...but if I mute Juno-d's channel, its coming in on Motifs 5-6.

Something in Logic is routing an EI instrument into the next ascending channel

Whats wrong?

Thanks

Each keyboard is routed L and R into the MOTU mk3 interface.

So ex: the Motif is routed into the channels 5-6.

In the MIx window of the MOTU, I did have the imputs of each keyboard set as stereo (thats how it was by default).

I deselected the stereo button via MOTU mix window, and changed each keyboard to mono.

This still didnt work.


I created an EI, and set the imputs to 5-6 for the Motif and I see nothing coming in on its channel via Logic. (And the Universal track mode is turned on BTW)

Just to try something, I changed the input of the motif to 7-8 from the EI window....then I see something coming in on the channel strip in Logic.


Again, its probably something small that I cant see right now.

But help me out in regards to the Motu mix wiondow.

Is that where this problem is starting?

Thanks

Another thing I would like to add, is my spoeakers are routed to the Main Outs of the MOTU.

However, in the MOTU Audio set up, the "Main Out Assign" is set to "Analog 1-2"

thats the only way I can hear anything.


I just dont see why "main out assign" wouldnt be signed to non-other than "Main Out".

I dunno...please help.

thanks

I'll try and help but it's a little tricky without actually being there and seeing how you have everything setup.


So lets get some basic info first...


First go to the Motu Audio Setup utility and take a screenshot of the 828 Tab in that utility. You will see in there how you assign the various outputs as defaults for Stereo Out and Main Outs...


Mine are setup as follows (bearing in mind I am using an Ultralite and not a 828 but the basics should be the same)


Default Stereo Input = Analog 1-2

Default Stereo Output = Main Out 1-2

Phones Assign = Main Out 1-2

Main Outs Volume = Main Outs


I have also unchecked the 'Enable Core Audio Vol Controls '


Now run CueMix and again please take a screenshot of the main Cuemix screen


Mine is set up as follows


Main Output is set to Main Out 1-2


Mix is set to Bus 1

Mar 31, 2013 11:07 PM in response to The Art Of Sound

OK, so I did all of this...

Default Stereo Input = Analog 1-2

Default Stereo Output = Main Out 1-2

Phones Assign = Main Out 1-2

Main Outs Volume = Main Outs


But now I cant hear the software instruments from Logic.

I can hear the External Instruments but thats because the local control from whichever keyboard Im triggering is still on.

If I switch the Main Out 1-2 to Analog 1-2 (from MOTU Audio setup) ...then I can hear the software instruments from Logic and I can turn of the local control from the EI and also hear that as well, but I dont get any input signal for the EI from its assigned channel via Logic.


I even played a video from youtube to see where the audio is coming out and I only get audio when the Main Outs is selected (from the MOTU Audio setup window),...as Main Outs 1-2, not Analog 1-2.

In Logic's Preferences... What have you selected under the Audio Settings?


For example, under I/O Assigments do you have the Stereo Output set to Output 1-2 (Stereo Output)?


and...


Do you have Software Montioring checked under the Devices's Core Audio Tab?


Next...


When you create a new Software Instrument track, are you selecting Output 1-2 for the Output?


Finally...


As for Clockworks.. Well, hang off a bit about all that... Let's get your Audio side worked out first....

Yes everything you just mentioned I have done.

What about if you go to (In Logic)

Options>Audio>IO Labels.

The column under "channel" output 1-2 and column under "provided by driver" Analog 1-2 is deselected.

I cant click the row.

Its as if Logic only read the output as analog 1-2...not "Main Out 1-2"


What in Audio MIDI setup.

How should that be setup?

When I clicked "Main Out" and clicked one of the speakers to test it...its LOUD STATIC...

If I select Analog 1-2 and click to test the speakers....nothing happens..

Apr 1, 2013 4:36 PM in response to SIMOOL

Bearing in mind I have Ultralites here.. so things may be slightly different...


In the Audio Midi Setup...


Audio Window..


Clock Source - Internal


Under Output Tab


Main Out

Source: Default

Format 44100.0Hz 2ch-24bit Integer


Master

1: Main Out 1

2: Main Out 2

3: Analog 1

4: Analog 2

5: Analog 3

...and so on until

11: S/PDIF 1

12: S/PDIF 2

13: Phones 1

14: Phones 2


(when Main Out is selected in the drop down menu higher up, then 1: Main Out 1 and 2: Main Out 2 are highlighted in Blue)


Now for the settings under the Input Tab


Master

1: Analog 1

2: Analog 2

3: Analog 3

...and so on until

9: S/PDIF 1

10: S/PDIF 2

11: Mix 1 Return 1

12: Mix 1 Return 2


For both Input and Output settings all Values and, dbs boxes are blank/empty and all Mute and Thru check boxes are unchecked.

For mine.. I have the following


Under Channel is Output 1-2


Under Provided by Driver is Main Out 1-2

Under User is a circle with a small dot in it

Under both Long and Short is Stereo Output

That line is greyed out and i cannot change any of the settings for that line.


All the other lines are not greyed out and settings can be changed.

All other lines are checked in the first column under the Channel heading and there is nothing under either the Long or Short column headers..

Ok I had a EUREKA! Moment..

Heres what I did.

Remember how when I would create an EI for lets say the Alesis.

Which is patched into the patchbay at inputs 1-2 and that was routed to inputs 1-2 into the 828 mk3.

But no signal would come in logic under inputs 1-2...only 3-4.

Well, I shifted each instrument over to the next input on the patchbay.

This time routing the alesis instead at inputs 1-2, to 3-4...but the alesis is still routed from patchbay 3-4 into inputs 1-2 at the 828 mk3.


I created an EI from Logic assigned the inputs of the alesis to 3-4 and I got signal into the channel.

I think what is happening here is that analog inputs 1-2 is also the mic/line inputs, and the mk3 wants to shift them over to the next channel...sounds confusing but you follow?


The other thing I did was assign the Main outs 1-2 back to Analog 1-2, and I can hear the software instruments from Logic as well as the EI's.


Now my only problem now is, When I play the EI, the notes a sustaining. Like mild playing....and the notes are sticking.

Whats going on now..lol.

Thanks for your help BTW.

Cool!


So.. next thing is.. if the External Instrument has an internal sound engine.. (Like the Motif for example) is Local set to Off in that keyboard's settings?


Also, check for any possible Midi feedback loops.. by unplugging ALL midi cables going FROM the external Instruments to the Midi Interface..... and use the built in Internal Caps Lock keyboard in Logic to play the External Instruments and see if you still get stuck notes etc...

Apr 1, 2013 8:23 PM in response to The Art Of Sound

Yes Local control is off.

Opened up CAPS LOCK and played EI from that, no sustain notes occured.

Its like if I play to fast or hard from the actual keyboard, then it sticks like crazy.

How about the "returned assigned" in MOTU Audio Setup? Whats that supposed to be.


And in the Audio MIDI Setup, I have each Keyboard routed to its designated port of the MOTU MIDI interface, but nothing is routed to the Audio Interface. I didnt think anything had to be routed to it, but just throwing everything out there.

The External Instrument's audio is coming up on another channel?
