That is the main purpose of the MIDI System Exclusive messages, precisely.
Almost all manufacturers of hardware MIDI synthesizers provide sysex messages
in order to store and retrieve sound configurations (programs) or modify
single parameters of the programs. The format of the messages is free, and as
long as you need.

Here is a general description, if you need it:

The MMA requires that you use a registered manufacturer ID, but only for
commercial products. There is a special ID = 0x7D that is intended for
educational or development use only, and should never appear in a commercial
design.
