Geoff,
You should be able to send it with Bome's SendSX:
The MIDI file would essentially just contain sysex data, and SendSX should be able to open it, then send it.? Synths are normally able to accept sysex at any time - you shouldn't need to do anything special to make it ready to accept it.
Scala might have an option to save as sysex too - I've never tried it.
SendSX is nice and simple to use, and is free to use for non commercial purposes - you're supposed to send Mr Bome a postcard, to register it, after a couple of weeks :)
Mostly, you'd just need to load the file, specify the MIDI Out port to use (if not already set), then press Send.
I use it for patch saving, mostly - almost any synth with MIDI can dump its edit buffer, or a specified patch, e.g. manually from a menu, or by sending a dump request to it (also from SendSX).? You can then save the receive window in SendSX, as a file.? Sending it back again loads it back into the synth, to the same location it came from.
