I'm in the same position. I have the full app and prefer it. They released the effects pack for Amplitube BEFORE they added ACP though to VocLlive, so for a while there it was the only way to get the vocal effects in Amplitube. I sort of got used tot he limitations. I'm looking forward to them being on the bus either way.
I know that SampleTank is another priority as well as the instrument apps and that we should have all of them on the table, but I'll be sure to vocalize (yes, pun intended) the number of requests to also push VocaLive on the bus (not in front of it or behind it).
so, no stereo yet. understandable.
