I don't know the specific models but briefly owned a Tascam 4-track and have worked with a Fostex unit. They often have two speeds, a pitch wheel and, in Tascam's case, lots of little switches to route the signal. Transports are quite good, using what we used to call electronic controls; i.e., not mechanical piano keys. -- "Americans must know the basic architecture of programs designed to protect them."(Senator Franken.)
