MTRX Studio Connection Matrix Problem with Bass Management

[ric982]

Hi,
I have a new MTRX Studio on v5.5.0 DADman (arrived about mid-april). I'm working on a 9.2.4 setup, but having a problem with the connection matrix misbehaving.

Short Problem description: Initially, I can create and remove connections from sources to the 9.2.4 output. But once I've turned on Bass Management, the connections in the connection matrix disappear. If I remove the bass management, the connections comeback, but cannot be altered and new sources added afterwards cannot be connected to these outputs. The connections whether shown or not are working.

Details:
What I originally tried to create was:
1- 9.1.4 source (Dante 1-14)
1 -9.1.4 source (AD 1-14)
1 -7.1 source (Dante 56-64)
1 - 9.2.4 (DA 3-17)

During the 1st creation of this, I started with 'default group' formats, later changed to customer group formats (SMPTE order at least up through 7.1 channels), and later changed the order to move Lw / Rw before Ltf Rtf Ltr Rtr.
The 9.1.4 final is L/R/C/LFE/Ls/Rs/Lrs/Rrs/Lw/Rw/Ltf/Rtf/Ltr/Rtr
The 9.2.4 final is L/R/C/Sub1/Ls/Rs/Lrs/Rrs/Lw/Rw/Ltf/Rtf/Ltr/Rtr/Sub2
Bass management is default with all channels sent to both subs and LFE sent +10 dB to both.

I tried to recreate this monitor profile two more times . On the 2nd try I tried importing some of the info from the first profile. On the 3rd try, I created the custom groups first and then the sources and output (no importing) with same results. Seems OK until the first time I turn on bass management. The MTRX Studio is behaving correctly for the connections that were created. Bass Management is going to both SUBs correctly.

I've created another monitor profile to simply and trouble shoot and its down to this:

1) One Stereo input (ADAT 1 Inputs 3/4).
2) One 2.1 output (DA Outputs 3/4/6) (L/R/Sub1 of the original 9.2.4)

All OK until I turn on Bass Management and again the two connections disappear when BM on and show when off but cannot be altered. New sources added cannot be connected to this output. Bass management is working to the one sub.

I created one more monitor profile where I configured two stereo sources to the one 2.1 output. Again this is working as expected, but once I turn on bass management, the connection section locks up on these outputs. I can switch between the two inputs or Sum them and that all works as expected with bass management going to the sub.

Another symptom. If I close the profile, the connection section is still there and the (9.1.4, 7.1, and 9.2.4) channel labels I added in the original profile are still showing on the source side and the output side and the outputs have light blue dots on DA 5, 7, 8, and 9 (C, Ls, Rs, Lrs ,Rrs). Even through there is no monitor profile and no connections.

So problem doesn't appear to be related to 2 subwoofers. Possible confused things by changing definition of customer groups when used by existing source/output?

AVID problem was opened but they have not responded for the last 7 days. So I"m asking here.

Anyone got some suggestions? Reset to Factory Default maybe?
