Good luck
Man you dont have a lot to work with. the bathroom usually has some acoustics to it, but you seem like you have enough echo already. I really would suggest if you plan on doing this again, invest in a tape recorder that is designed for that. Even then the only tape recoders I know...
I got the vs 890 also
I'm not to sure what it is you did wrong. I could not see the problem in your steps. I do know there are more than just one way to record. here is the way I do it.
first: Press any status track 1-8 and press "Clear" at the same time.- this will clear any assigned tracks...
