As we have just been talking about, to send sysex you need to use the .tx command
.tx $F0 43 45 val $F7
for example, but we have also discovered that the BC can't react to these messages coming back (as far as we know - feel free to experiment)

Not too sure about the leading 00 ?
F0 01 20 01 01 P LSN(val1) MSN(val2) F7
val0.3 low nibble
val4.7 high nibble
.tx $F0 $01 $20 $01 $01 P val0.3 val4.7 $F7
Just in case this is really a 14bit number divided into two 7bit numbers you should use
val0.6 low byte
val7.13 high byte

No, sorry, as the BC doesn't respond to sysex to reset its controllers value
To do this you would need a program inbetween the BC and the evolver and the BC would just use CC messages, the program converts to sysex and sends it to the synth and handles the MIDI back the other way.
Best of luck
