Does support even read these forums? I've had  no response so far, Ive written to the email support twice. Not even an acknowledgment that they received the mail.
Anyway I think now that the latency issue  is mostly caused by the selection of the submix in the GUI. If a submix selection CC is sent for each change in value of a particular fader then the GUI does it's submix selection routine 128 times for a full fader movement. If two faders are moved at once it would be 256 times etc. Presumably each selection involves bidirectional communication on the firewire buss which would add further to the latency and load on the system.
So to solve the problem would probably be to have an option to disallow the change of focus in the GUI for midi selection of the submix bus, though I imagine the target for incoming CC's is determined by the GUI focus.
The option of not having to change GUI focus would also make sense for remote mixing even from a single remote user. I mean if you are not looking at the screen it wouldn't matter. The GUI could be updated only when the focus is changed by the mouse or there could be an option for either mouse or midi.

Yes that's right I'm thinking something with the functionality of an Aviom system. It could be done with just a simple midi controller, part of the idea that I had was that using a $50 or less midi controller (korg nano) would enable something similar to an Aviom at a far cheaper cost $3000 for a 6 way setup versus $300 and a 6 way headphone amp, ah yes and of course you would need usb over cat 5 extenders which are only about $10 each on ebay and a USB hub. This would be good for a studio, maybe a band would want to go wireless with Ipads. Actually Ipads or any wireless laptop functioning as a midi controller would mean less cables to lay out for each player.

Hi Daniel,

thanks for the reply.
It wasn't really whether or not one or to or more controllers were controlling TM that mattered, it was the ability to simultaneously adjust two different submixes. I guess that would mean either having a different CC for each fader and pan in every submix. Maybe there isn't enough CC's to control a every fader in a 64 channel TM setup, but if it was just say 64 inputs to 32 stereo pairs or better still they were assignable until you ran out of CC's it would be great.
I can see you might not be able to put that into the firmware for stand alone operation but surely in TM software it could be done?
The other option would be have it so the midi selection of the submix doesn't change the GUI submix focus, assuming that's what causes the latency problems when sending submix selection CC's along with each change in value of a given faders CC's.
I know the scope fusion platform offers midi learn of all mixer functions (dam why did I sell my creamware card) and the old yamaha DSP factory cards did it to.
With the price of an Aviom system my money goes to the first interface I can find that is as good as RME but enables more complete midi control.
