I don't know what you mean by 'Programs 102, 103, etc'.
The numbers 102 etc look like they could be Midi Controllers, these specific numbers are listed as 'undefined' which means that they exist, but are not normally used. This means that they are available for a manufacturer to use for their own purposes. Such as muting. A controller is usually a three byte series. The first byte would be (in hex) Bc where the B represents 'Control Change' and the c would be the Channel 0 - F. The second byte would be the Controller Number, i.e. 66 (102 in decimal). The third byte would be a number, and exactly how this might be used I don't know. 0 might be off, 1 might be on, or if there's a degree of mute then this value might be 0 to 7F. Does the manual offer any examples.
The other device then would need to be told of the three values to be sent,, and when, i.e. there is a key to press which sent the controller codes to be received by the other device.
Does this make any sense to you?
