Yes, probably…
Depends what tracks you recorded onto, a normal cassette is 4 tracks, 2 on one side and 2 on the other
A 4 track like the 246 is 4 tracks all going the same way i.e. on one side.
So if for instance you had all four tracks recorded from the 246, when played back in a normal cassette you’d be able to play 2 tracks back at half speed the correct direction and turn the cassette over and get the other two tracks back but backwards!
So depending, you could transfer the audio over and double the speed and/or reverse the results accordingly.
