Hi Sherry
Good to hear from you on this awfully quiet forum,everybody just busy minding his own bussiness ,I guess.
I havenīt heard of Transkriber although Reed Kottler is well known to me because of a cute little device (LBR 100 ) which lets you filter out all voices except the bass part ( if you want to),great for copying bass parts in those days.
You may want to check out
www.renegademinds.com if you are looking for a free ( donation support )and simple slowing -down machines.
I have tried the Guitar and Drum trainer 2 version which proved to be sufficient for my demands.
Hope this will help you
Keep on grooving ( besides taking care of husband,kids and labs, wallers,constructors.... ).
Cheers
Djim
