I've had my 2488neo for about a year now, but only recently started working with it in earnest - and ran into a strange issue. My intent was to record vocals on track 1 via microphone (plugged into the first xlr jack) and guitar on track 2 - plugged into H - but routed to track 2. However, on playback, what I get is everything on track 1, combined - even though I see VU level movement on track 2 - the track2 fader does nothing - If I only play back track 2, I get nothing - even though I see the VU meter moving - and it's got a pretty good sigtnal. I t hink somehow I must have told it to combine the two onto track 1 (by accident) - but I thought I should be able to hear the channels separately. This has happened on occasion with other tracks, so I'm thinking I must be doing something wrong with the track assignment / record buttons. Note - sometimes when I press input a (until it blinks) and then press the track I want to assign it to (say #1) - #2 gets activated at the same time - very confusing. Same thing happens when I go through the sequence of Selecting input A - asign to track 1 - then select input H and assign to track 2 - both 1 & 2 light up (apparently assigned to input H - which I think is how my situation occurred. I've looked at the manual - but it's basically walking through assigning a single input to a single track - doesn't cover multiple inputs and multiple tracks & how to make sure they are separated,. Thanks in advance for any input to this,.
