the passport midi interfaces were not top tier (my opinion)
as they were software developers they made available interfaces for a bunch of different computer platforms
probably all using the same box/packing materials but labeled for which platform version: ie commodore 64

they probably made versions for other common 80s computer platforms such as the Apple II etc
in the photo you can see the passport interface is more of a "game-cart" type format with midi wire leads coming out the back of it, the passport midi interface (1985ish) definately predates the v4001 (1988)
heres a link to an article on muzines
http://www.muzines.co.uk/articles/passport-midi-4-software/7991
looks like they had a number of products, most likely the hardware was needed/provided to support master tracks pro software on many different computer platforms + different levels of features/cost; models included the MIDI/4, MIDI/8 Plus etc heres the ibm version discussed in an article in (1990) (probably DOS baseD?)
http://www.muzines.co.uk/articles/passport-mastertracks-pro/423
actually it looks like midi/4 + midi/8 were actually software packages

then it was ported to Windows 3.1 in (1992) :

hers a look at the original contents/ packing materials for the c64 version

here the back of the box detailing the different versions/platforms
this box must have been prior to 1990 as it doesnt mention the IBM/DOS or IBM/Windows versions

looks like they started out with only apple IIe -- C64/128 -- and the MacPlus/SE/IIs -- and then added drum/tape sync versions for both C64 + AppleIIe, i wonder if they did an amiga version
