The song I just finished in HMB was a track I've already worked a lot in live since ages.
I rendered the tracks individually thru the master (24bits 44khz), because I had some sidechain compression here and there, automations of filters, volumes, and so on. (well, writing this, I realise that I didn't need to render thru the master, did I ??

)
I just tweaked the faders so as to have wavs not going above -6db for peaks, just my sub bass track was rendered at much higher volume than the others so as to be able to adjust it at will in HMB (the sub in that song was not really present)
I did NO automation in HMB (but it seems relatively easy, for the console parts)
I guess in some future I may use automations in HMB, but I'll keep on building nearly finished mixdowns in live first, because I'm used to Live, I love live, I have a good workflow within live, and also because I'm not at all used to ARDOUR...
It is then quick and easy to finish it in HMB, and have that GREAT WARM SPACEY sound.
believe me, just using HMB faders, EQs, one or two mixbusses with little tape saturation, even not touching the pan pots... you clearly feel something HUGE.
Already in love
