Most significantly monitoring make sure it’s set so that all 8 input channels are monitored then you will hear what’s being sent in. The balance between monitoring what’s coming in and what’s going out from the pc should also be set.
Pro tools does not seem to work comfortably with the behringer 1810 in particular it miss identifies the output ports. This may be rectifiable (will explore). Have explored – reset audio io to default worked but should be checked as it may revert.
In order to send audio to the tchelicon my solution is to sync protocols and Ableton – protocols sends the audio via the um 202. Ableton can capture the resulting helicon processed audio. Either protocols or Ableton can send the midi. Is there a better way of doing this and sending the audio to be processed by the Tc helicon from Ableton but excluding it from the mix (will have to figure this out). I don’t think there is as I think it results in a a feedback loop with audio out signal intended for the helicon coming back in after processing to Ableton.
The tc helicon resets if you send it certain commands. I have now set it to filter them out but this may not work.
For convenience audio from the CD player, record deck, cassette player, K6 and DEC TALK can be passed from the Mackie via sends into channel 1&2 of the Behringer. Obviously this extends the signal path but maybe useful. I can continue to use the Mackie as an all round mixer for playing records and things.
Don’t forget you may have turned the volume of the Mu10 down to exclude it from the mix but it should be possible to exclude it using the DAW.
The MU 15 is internally the same as the MU 10 and could replace it.
The XG 1000 Card has the extra sounds and could use PCDIF to send into UM 1820 if 32 channels or extra instruments are required
