2. - Can you send sine waves from a source track, and record to a  new track and compare the zero crossing positions? One sample off could be a rounding issue because there is a portion of a sample involved on the AD side. If it is more than 2 samples discrepancy then something else is going on. 

Let me know

1. alright, do you know the rme totalmix software. it allows individual phase switching on of every channel and ms decoding of stereo channels (you can have a mid side mic setup and in the totalmix software (which has no dsp power as far as i know)  it is possible to encode that to a true stereo signal.. 

it is just routing and one track must be phase inverted, no real processing of the signal..

 so sadly no ms decoding??

so would it be possible to add phase invert button for every channel? (then i can perhaps build up my own ms matrix)

2. i will look into that on tuesday. but paul, perhaps you can try it too.. should not be different in your setup,... unless aurora has used different converters in different serialnumbers..

 

why would be an inverted phase button per channel so important?

when working in a professional mac environment (but without a mixer desk) i wanna overdub tracks within a project in realtime (with no latency) 

direct monitoring does not exist on the mac platform, but it is always possible to open the track within the lynx mixer application. (great!!)

when i work as a producer and want to record some multimiced sources, i need to monitor those in summation to check phasing issues. therefore it would be a great addition to the mixer to be able to switch the phase from channel to channel to identify phasing problems.. 

when this will be not provided by a professional recording solution, the drawback is really tremendous. 

for the recording engineer point of view it doesnt matter if the phase inverted signal is recorded or the real input signal (you can always invert the phase within the recording software).. but for monitoring purpose it is a must have.

thx for your effort!

greets. re

So I'm afraid a phase switch is not part of the Lynx Mixer feature set. Your request is noted and will be added to the wish list. Your points make good sense for in-the-box operation. 

As to testing the loop test alignment, this has been tested here. The question would be if there is some factor in your system that is impacting that. 

i will try the loopback again tomorrow.. 

so my daw is: cubase 6.0.7

dsub25 vovox ins and outs

and a great signex pst96 d25p patchbay which is half normalized on the aurora channels.. 

so which factors do you think of?

i wonder cause with the rme fireface the same loopback test is working with complete phase cancellation.

so at the end of the day the only difference was the audio interface.. 

greets.

however, is a phase invers button possible for a further software update within the aurora mixer? thx sw
