2nd OT I just bought, this is MK1, (just put in the latest firmware 1.40 yesterday) I had a MK2 w/similar problems— could never get live sampling to work…
Recording from a mixer out into AB, I see the signal green/red light in Record AB, the little tape is moving and I assume recording, and I playback with a trig initiated, I literally watched the freakin video 10 times. I rebooted to factory setting etc., my head is gonna explode.
Something with the sampling/loop/edit menu no doubt. o assignment of the sample.
