I've read the manual and tried this a few times and can't figure out what I should be doing. I'd like to record a chord progression onto the sequencer. Here's the order I'm pressing buttons:RecordPress the first chordHold the chord while pressing Destination/tie to make it longerLet go of the first chordPress the second chordHold the chord while pressing Destination/tieLet go of the second chordPress the Record to stopUpon playing it back, I only hear the first chord, then a rest for the space the second chord should be in. What am I doing wrong?
