Im not getting the fader thing happening on my PC with Live9 ??
with the channels its fine, theyre treated as stereo channels in Live...
so master in Spark is channel one (or the channel youve loaded the VST into, of course you could also route this out too)
then channel 2 on Spark = 1/2 in Live
channel 3 = 3/4
channel 4 = 5/6
