I'm trying to set up Loopback in Mainstage 2 to do live looping without syncing to a tempo. I have sync disabled, fine, I have a FCB1010 with the UnO chip programmed and stomp boxes mapped to the Play, Stop and Rec transport buttons, and all that is working. I start playing my instrument then when I'm in the groove I hit the record footswitch and Loopback starts recording. Except, it doesn't start right away. The delay might be small or quite significant but other than looking at the waveform display, there's no indication that it isn't recording yet. So it doesn't "keep up" with what I'm playing because it doesn't start when I hit the record foot switch. by the way, the panel indicator lights as soon as I press the footswitch. I have a MBP 2.53 GHz which is almost brand new so lot's of disk space. I'm using a Echo Audio AudioFire4 with a 128 sample buffer for 11.9ms latency. This delay is way more than 11.9ms. I have even tried playing against the click and it's not me, it's the machine. Anyone run into this?
