Hi I am new to this board and I have just recently obtained a x-34. This came as a result of my tascam porta 7 dying on me after many years of faithful recording. My question comes after my attempt at solving this problem through reading the manual has failed. Unless I am missing something here, which I hope I am, I may not be very happy with the x-34. On my porta 7 when I had recorded a track or two I could listen to those tracks while hearing myself practicing the part I was going to laydown next through the monitors. On the x-34 once I have a track laid down if I push the play button to hear the track I can find no way to also here lets say a guitar part that I am working out to record. The only way I can hear that new part I want to record and the parts already recorded is to actually press the record button on the tape controls. I imagine that if I have to do this several times till I get the part right eventually the tape quality on that track will decrease. Like I said I hope I am missing something that will allow me to hear the recorded track and my-self working out the new part without recording to do so. Hehe reading this message again I hope it makes sense and I thank you in advance for your time.
