Hey there,
I generally erase the whole tape after a backup, but this time I would like to erase 3min lenght (too long for lift), is there a fast way to do it ?
THank you 
cut it up into less than 90 second pieces and lift
I’ve got a max lift of 22sec 
I’ve done this way, but is this the only way ?
90 secs i think is for single tape tracks. 22 sec is for all 4 at once.
a couple quick ideas,
in the box u could record the section u want to keep onto album, erase entire tape, then record back onto tape. not a great one b/c u lose your track separation. unless u recorded each track separately onto album, but that might be a pain to re-align when going back to tape?
if u use a computer and the usb disk thing, u could edit your tape files there to keep what u want then reload them maybe too.
You’re right @docshermsticks, I’m a bit tired 
Don’t you think that editing tape files with a third party software could corrupt them ?
Someone suggested deleting long Lifts,travelling from end of tape to beginning .It’s faster.
I’ve done like that yes
I was wondering why the lift button is labellized “Lift/Erase”
