Greetings Kevin,
Welcome to the confusing world of MIDI. MIDI is a very flexible standard and can be used in many ways. It is not surprising that different instruments respond differently. In addition to the various standards and instrument sets, there are also system exclusive messages that can be impossible to understand without the manufacturer's documentation.
Conversion from one format to another may be simple or it may require a bunch of reading of manuals and lots of fiddling. If you have the documentation for your instruments you may be able to find a way to insert a patch or bank select message to select the right voices. Some instruments such as the Disklavier will play anything on channels 1 and 2 as piano as Carol said. Usually, they will respond to other channels with the appropriate instrument as long as the instrument banks of the recording and playback instrument are the same. If they are not, it may only be necessary to find similar instruments and to send messages to select those instrument for each channel on which there is a different instrument. Once you figure this out it may be worth the effort to write a program to modify the files, if you have or will have a lot of them.
I wrote a program that sends patch and bank select messages to a MIDI device but I never figured out if it really works correctly. If you can connect a computer to your MIDI instrument and send messages from a windows program, this might be useful to figure out what is needed. Still, it will be very helpful to have the manufacturer's manuals as there are too many combinations of bank and patch to try to find the right ones by trial and error. Let me know if you want to try the patch and bank sending program. I would like to know if it does work on anything other than the synth I tested it with.
