Just using a mouse. I really wish I had a control surface sometimes. More than that, a nice big console. I actually really like the look of the Audient ASP 2802, which may be my next goal.
I still have to figure out automation in Ardour as well as a couple of routing things. I just loaded mixbus onto my iMac, which gives me right click functionality. Pretty essential in Mixbus. It won't recognize a control click on my laptop. Got the chance to just load up my jack/logic/mixbus 40 channel mixer template, and the CPU load was just over 20%, so I shouldn't hit the wall on these mixes. I still think I'll be transferring the files over to Ardour for final mix down.
Hope I can get some good results!
