ADAT problem (Motu Ultralite Mk5)

[repeatle]

Is anyone here running Push 3 standalone with Motu Ultralite Mk5?
The ADAT works fine for the inputs of Push 2 (I can record several external sources at once) but I cannot get the separate outputs to work.

I assume there's a setting on the Motu that I'm missing?

Will try to connect the Push to my other ADAT-compatible interfaces (Ferrofish 16 and Presonus Quantum 2626) when I'm in the studio next week.
(Never mind that the signal is hot in the pic )

You do have TWO Toslink cables connected (one in, one out)?

I also have a mk5 which I bought recently for expanding my Push 3 - but I've not hooked it all up yet.

Try the outputs starting at 9/10.
I haven't been able to route 5/6 or 7/8 yet.

Yes, I've got two cables connected (in and out).

Managed to get it working today!

Starting at 9/10 (thank you, James!) and from there I went into CueMix (the mixer / routing system for the Motu) and adjusted which ADAT channels should be routed to which analog outputs of the Ultralite. I understood something was odd when any ADAT channel would only be sent to the main out of the Ultralite so I understood that the problem must be in CueMix.

Push 3 Standalone works perfect with Motu Ultralite Mk5 here now. Both multiple ins and out.

Thank you!

The whole 9/10 thing is puzzling to me. Why, when the P3 only has two ins and two outs, do the additional channels start at 9 & 10???

On the inputs, the listed channels start at 1/2 then jump to 9/10. Why are they shown even when no external I/O is connected? Why no 3 to 8?

Then on the outs, there's no jump from 1/2 to 9/10. Instead it also shows 3 to 8. Again, all shown regardless of physical I/O connection.

Confusing.

I think it does something like this:

1/2 - Main out from Push
3/4 - Can be assigned to headphones (not sure)
5/6 - This is the Pedal/CV output 1 of Push
7/8 - This is the Pedal/CV output 2 of Push

And then 9/10 etc is the ADAT out. Funny thing - I tried to send audio thru the Pedal/CV outputs (5/6 and 7/8) and it worked! Sounded very lofi and loud though. I'm sure some producer will like this "instant bit crush" thingy

[repeatle]

Ok here it is:

1/2 - Main out from Push
3/4 - Can be assigned to headphones out
5/6 - This is the Pedal/CV output 1 of Push
7/8 - This is the Pedal/CV output 2 of Push
9/10 - ADAT out 1/2
11/12 ADAT out 3/4
13/14 - ADAT out 5/6
15/16 - ADAT out 7/8

OK thanks, so I guess due to the ADAT outputs starting at 9/10, it kinda makes sense for the inputs to start there too (despite the gap).

Reading up on the the Pedal/CV sockets, there's mention of them being 12 bit, which could explain the crunchiness. Still a bit odd that they're listed as audio outputs if they're not intended as such.

Thinking out loud here, it might be nice to have little icons/text next to each in/out to show what they're for or what they're set to (perhaps M for master, H for headphones, CV for CV and an A for ADAT?).

That's a nice idea. If you're on the Push beta program on Centercode, you could make a Suggestion for this.

Done!

I've setup MOTU Ultralite mk5 to work with Push 3, works fine appart from MOTUs output ports 7/8.

When I send audio to Abletons outputs 13/14, which is mapped to MOTUs outputs 7/8, I get a clean audio signal coming out of 7/8, but there is a weird bleed into almost all the other MOTUs input channels. And the bleed is the orginal audio signal, but with some crazy heavy high frequency distortion.

This does not happen when I connect the Ultralite directly to my computer through USB, all the output channels work flawlessly, and no bleed on output 7/8.

I've set up both Ableton and the MOTU to work on 48kHz, on MOTU the clock source is Optical, in Cuemix I've routed the corresponding ADAT channels to the right Line Mixes. Shouldn't be a problem with my settings I assume.

Anyone else experience this?

A non-Motu experience: I do get noise distortion from time to time from the Push built in DAC. Sometimes I've made the distortion go away by changing the kHz setting to something else and then back again.

Thanks, but I've tried that. Now the behaviour has changed, the bleed is gone, but the 7/8 output just doesn't work. But it still works when using the MOTU as a standalone interface.

I am getting noise and distortion issues with the MOTU Ultralite MK5. I have even returned mine for a replacement, but still have these problems. Tried with different ADAT cables as well.

The current weird behaviour is this:

- Everything works fine initially.
- I tweak the filter on one of the connected synths. Once I get to a certain point when the resonance starts to self oscillate, the distortion starts, on every connected channel, not only in the one with incoming audio. It doesn't matter how low the level is of the incoming signal, this noise will start no matter what.

Tried changing to different audio rates, sample rates, but the issue remained the same. I am now using the MOTU directly connected to my computer, however, I will probably return it and try a different audio interface.
